Storing quantum coherence in a quantum dot nuclear spin ensemble for over 100 milliseconds Harry E. Dyte, Santanu Manna, Saimon F. Covre da Silva, Armando Rastelli, Evgeny A. Chekhovich Nature Communications, 2026 States with long coherence are a crucial requirement for qubits and quantum memories. Nuclear spins in epitaxial GaAs/AlGaAs quantum dots are a great candidate, offering excellent isolation from external environments and on-demand coupling to optical flying qubits. However, coherence times are limited to ≲ 1 ms by the dipole-dipole interactions between the nuclei and by the nuclear quadrupolar coupling to inhomogeneous crystal strain. Here, we combine strain engineering of the nuclear spin ensemble and tailored dynamical decoupling sequences to achieve nuclear spin coherence times exceeding 100 ms. Recently, a reversible transfer of quantum information into nuclear spin ensembles has been demonstrated in quantum dots: our results provide a path to develop this concept into a functioning solid-state quantum memory suitable for quantum repeaters in optical quantum communication networks.
Cascaded Metasurface Interferometer for Multipath Interference with Classical and Quantum Light Rebecca Aschwanden, Nicolás Claro-Rodríguez, Ruizhe Zhao, Patricia Kallert, Tobias Krieger, Quirin Buchinger, Saimon F. Covre da Silva, Sandra Stroj, Michele Rota, Sven Höfling, Tobias Huber-Loyola, Armando Rastelli, Rinaldo Trotta, Lingling Huang, Tim Bartley, Klaus D. Jöns, Thomas Zentgraf ACS Photonics, 2026 Beamsplitters represent fundamental components in both classical and quantum optical systems, enabling the distribution of light, as well as the generation of interference, superposition, and entanglement. However, optical networks constructed from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues, as the number of required beamsplitters scales quadratically with the number of optical modes for a fully connected network. Metasurfaces offer a promising route to overcome these constraints. By manipulating light at the wavelength scale, compact optical components with advanced functionalities can be constructed, which address several modes simultaneously. In this work, we design and experimentally utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a multimode interferometer composed of two cascaded metasurfaces. We characterize the individual and cascaded metasurfaces by using classical light, showing controllable splitting ratios through tunable phase relations. We then expand the approach to quantum light, employing single photons to demonstrate second- and third-order photon correlations as well as single photon interference across multiple spatial paths. These results establish metasurface-based multiport beamsplitters as a scalable and reconfigurable platform bridging classical and quantum photonics.
Low-Density InGaAs/AlGaAs Quantum Dots in Droplet-Etched Nanoholes Saimon F. Covre Da Silva, Ailton J. Garcia, Maximilian Aigner, Christian Weidinger, Tobias M. Krieger, Gabriel Undeutsch, Christoph Deneke, Ishrat Bashir, Santanu Manna, Melina Peter, Ievgen Brytavskyi, Johannes Aberl, Armando Rastelli Nano Letters, 2026 High Resolution Image Download MS PowerPoint Slide Over the past two decades, epitaxial semiconductor quantum dots (QDs) have demonstrated very promising properties as sources of single and entangled photons on-demand. Among different growth methods, droplet etching epitaxy has allowed the growth of almost strain-free QDs, with low and controllable surface densities, small excitonic fine structure splitting (FSS), and fast radiative decays. Here, we extend the technique to In(Ga)As QDs in AlGaAs, thereby increasing the achievable emission wavelength range beyond that accessible to GaAs/AlGaAs QDs while preserving some of the key advantages of this growth method. We observe QD densities of ∼0.25 μm –2, FSS values as small as 3 μeV, and short radiative lifetimes of ∼300 ps, while extending the achievable emission wavelength to ∼900 nm at cryogenic temperatures. We envision these QDs to be particularly suitable for integrated quantum photonics applications.
Experimental Measurement of the Reappearance of Rabi Rotations in Semiconductor Quantum Dots Lukas Hanschke, Thomas K. Bracht, Eva Schöll, David Bauch, Eva Berger, Patricia Kallert, Melina Peter, Ailton J. Garcia, Saimon F. Covre da Silva, Santanu Manna, Armando Rastelli, Stefan Schumacher, Doris E. Reiter, Klaus D. Jöns Physical Review Letters, 2025 Phonons in solid-state quantum emitters play a crucial role in their performance as photon sources in quantum technology. For resonant driving, phonons dampen the Rabi oscillations, resulting in reduced state-preparation fidelities. The phonon spectral density, which quantifies the strength of the carrier-phonon interaction, is nonmonotonic as a function of energy. As one of the most prominent consequences, this should lead to the reappearance of Rabi rotations for increasing pulse power, according to the theoretical predictions in Vagov et al. [Phys. Rev. Lett. 98, 227403 (2007)PRLTAO0031-900710.1103/PhysRevLett.98.227403]. In this Letter, we present the experimental demonstration of the reappearance of Rabi rotations for a resonantly driven quantum dot.
Passive demultiplexed two-photon state generation from a quantum dot Yusuf Karli, Iker Avila Arenas, Christian Schimpf, Ailton Jose Garcia Junior, Santanu Manna, Florian Kappe, René Schwarz, Gabriel Undeutsch, Maximilian Aigner, Melina Peter, Saimon F. Covre da Silva, Armando Rastelli, Gregor Weihs, Vikas Remesh Npj Quantum Information, 2025 High-purity multi-photon states are essential for photonic quantum computing. Among existing platforms, semiconductor quantum dots offer a promising route to scalable and deterministic multi-photon state generation. However, to fully realize their potential, we require a suitable optical excitation method. Current approaches to multi-photon generation rely on active polarization-switching elements (e.g., electro-optic modulators, EOMs) to spatio-temporally demultiplex single photons. Yet, the achievable multi-photon rate is fundamentally limited by the switching speed of the EOM. Here, we introduce a fully passive demultiplexing technique that leverages a stimulated two-photon excitation process to achieve switching rates only limited by the quantum dot lifetime. We demonstrate this method by generating two-photon states from a single quantum dot without requiring active switching elements. Our approach significantly reduces the cost of demultiplexing while shifting it to the excitation stage, enabling loss-free demultiplexing and effectively doubling the achievable multi-photon generation rate when combined with existing active demultiplexing techniques.
Quantum teleportation with dissimilar quantum dots over a hybrid quantum network Alessandro Laneve, Giuseppe Ronco, Mattia Beccaceci, Paolo Barigelli, Francesco Salusti, Nicolas Claro-Rodriguez, Giorgio De Pascalis, Alessia Suprano, Leone Chiaudano, Eva Schöll, Lukas Hanschke, Tobias M.

Rota, Francesco Basso Basset, Armando Rastelli, Fabio Sciarrino, Klaus D. Jöns, Rinaldo Trotta Nature Communications, 2025 Photonic quantum information processing in metropolitan quantum networks lays the foundation for cloud quantum computing, secure communication, and the realization of a global quantum internet. This paradigm shift requires on-demand and high-rate generation of flying qubits and their quantum state teleportation over long distances. Despite the last decade has witnessed an impressive progress in the performances of deterministic photon sources, the exploitation of distinct quantum emitters to implement a quantum relay among distant parties has remained elusive. Here, we overcome this challenge by using dissimilar quantum dots whose electronic and optical properties are engineered by light-matter interaction, multi-axial strain and magnetic fields so as to make them suitable for the teleportation of polarization qubits. This is demonstrated in a quantum network harnessing both fiber connections and a 270 m free-space optical link connecting two buildings of the Sapienza University campus in Rome. The protocol exploits GPS-assisted synchronization, ultra-fast single photon detectors as well as stabilization systems that compensate for atmospheric turbulence. The achieved teleportation state fidelity reaches up to 82 ± 1%, above the classical limit by more than 10 standard deviations. Our field demonstration of all-photonic quantum teleportation opens a new route to implement solid-state based quantum relays and builds the foundation for practical quantum networks. While several advancements have been made in the use of on-demand solid-state quantum emitters for quantum communication, using them to realise a quantum relay among remote parties had not been realised so far. Here, the authors fill this gap by realising all-photonic quantum state teleportation with photons generated by distinct remote quantum dots.
Keeping the photon in the dark: Enabling quantum dot dark state control by chirped pulses and magnetic fields Florian Kappe, René Schwarz, Yusuf Karli, Thomas Bracht, Vollrath M. Axt, Saimon F. Covre da Silva, Armando Rastelli, Vikas Remesh, Doris E. Reiter, Gregor Weihs Science Advances, 2025 Dark excitons in quantum dots are not directly optically accessible, which has limited their use in practical applications. Nevertheless, they offer promising features such as substantially longer lifetimes compared to bright excitons, making them attractive candidates for quantum information processing. While previous theoretical and experimental studies have explored their potential, their full capabilities remain largely untapped. In this work, we demonstrate an all-optical storage and retrieval of the spin-forbidden dark exciton in a quantum dot from the ground state using chirped pulses and an in-plane magnetic field. Our experimental findings are in excellent agreement with theoretical predictions of the dynamics calculated using state-of-the-art product tensor methods. Our scheme enables an all-optical control of dark states without relying on any preceding decays. This opens up an unexplored dimension for optimal quantum control and time-bin entangled photon pair generation from quantum dots.
Electric-Field Control of Photon Indistinguishability in Cascaded Decays in Quantum Dots Gabriel Undeutsch, Maximilian Aigner, Ailton J Garcia, Johannes Reindl, Melina Peter, Simon Mader, Christian Weidinger, Saimon F. Covre da Silva, Santanu Manna, Eva Schöll, Armando Rastelli Nano Letters, 2025 Photon indistinguishability, entanglement, and antibunching are key ingredients in quantum optics and photonics. Decay cascades in quantum emitters offer a simple method to create entangled-photon-pairs with negligible multipair generation probability. However, the degree of indistinguishability of the photons emitted in a cascade is intrinsically limited by the lifetime ratio of the involved transitions. Here we show that, for the biexciton–exciton cascade in a quantum dot, this ratio can be widely tuned by an applied electric field. Hong-Ou-Mandel interference measurements of two subsequently emitted biexciton photons show that their indistinguishability increases with increasing field, following the theoretically predicted behavior. At the same time, the emission line width stays close to the transform-limit, favoring applications relying on the interference among photons emitted by different sources.
Tuning the Coherent Interaction of an Electron Qubit and a Nuclear Magnon Noah Shofer, Leon Zaporski, Martin Hayhurst Appel, Santanu Manna, Saimon Covre da Silva, Alexander Ghorbal, Urs Haeusler, Armando Rastelli, Claire Le Gall, Michał Gawełczyk, Mete Atatüre, Dorian A. Gangloff Physical Review X, 2025 A central spin qubit interacting coherently with an ensemble of proximal spins can be used to engineer entangled collective states or a multiqubit register. Making full use of this many-body platform requires tuning the interaction between the central spin and its spin register. GaAs quantum dots offer a model realization of the central spin system where an electron qubit interacts with multiple ensembles of ∼104 nuclear spins. In this work, we demonstrate tuning of the interaction between the electron qubit and the nuclear many-body system in a GaAs quantum dot. The homogeneity of the GaAs system allows us to perform high-precision and isotopically selective nuclear sideband spectroscopy, which reveals the single-nucleus electronic Knight field. Together with time-resolved spectroscopy of the nuclear field, this fully characterizes the electron-nuclear interaction for control. An algorithmic feedback sequence selects the nuclear polarization precisely, which adjusts the electron-nuclear exchange interaction via the electronic g-factor anisotropy. This allows us to tune directly the activation rate of a collective nuclear excitation (magnon) and the coherence time of the electron qubit. Our method is applicable to similar central-spin systems and enables the programmable tuning of coherent interactions in the many-body regime. Published by the American Physical Society 2025
Robust single-photon generation for quantum information enabled by stimulated adiabatic rapid passage Yusuf Karli, René Schwarz, Florian Kappe, Daniel A. Vajner, Ria G. Krämer, Thomas K. Bracht, Saimon F. Covre da Silva, Daniel Richter, Stefan Nolte, Armando Rastelli, Doris E. Reiter, Gregor Weihs, Tobias Heindel, Vikas Remesh Applied Physics Letters, 2024 The generation of single photons using solid-state quantum emitters is pivotal for advancing photonic quantum technologies, particularly in quantum communication. As the field continuously advances toward practical use cases and beyond shielded laboratory environments, specific demands are placed on the robustness of quantum light sources during operation. In this context, the robustness of the quantum light generation process against intrinsic and extrinsic effects is a major challenge. Here, we present a robust scheme for the coherent generation of indistinguishable single-photon states with very low photon number coherence using a three-level system in a semiconductor quantum dot. Our approach combines the advantages of adiabatic rapid passage and stimulated two-photon excitation. We demonstrate robust quantum light generation while maintaining the prime quantum-optical quality of the emitted light state. Moreover, we highlight the immediate advantages of the implementation of various quantum cryptographic protocols.
