Bipartite entanglement in a nuclear spin register mediated by a quasi-free electron spin [PDF]
Nature CommunicationsQuantum networks will rely on photons entangled to robust, local quantum registers for computation and error correction. We demonstrate control of and entanglement in a fully connected three-qubit 13C nuclear spin register in diamond.

Nature, 2017 Advanced photonic nanostructures are currently revolutionizing the optics and photonics that underpin applications ranging from light technology to quantum-information processing. The strong light confinement in these structures can lock the local polarization of the light to its propagation direction, leading to propagation-direction-dependent ...

Optical driving, spin initialization and readout of single SiV− centers in a Fabry-Perot resonator
Communications Physics, 2023 Large-scale quantum communication networks require quantum repeaters due to the signal attenuation in optical fibers. Ideal quantum repeater nodes efficiently link a quantum memory with photons serving as flying qubits.

Continuous entanglement distribution over a transnational 248 km fiber link
Nature Communications, 2022 Fibre-based entanglement distribution represents a key primitive for quantum applications such as QKD. Here, the authors demonstrate it across 248 km of deployed fiber, observing stable detected pair rates of 9 Hz for 110 h.

High-performance cavity-enhanced quantum memory with warm atomic cell
Nature Communications, 2022 Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and ...

Quantum optics with quantum gases [PDF]
Laser Physics, 2009 Quantum optics with quantum gases represents a new field, where the quantum nature of both light and ultracold matter plays equally important role. Only very recently this ultimate quantum limit of light-matter interaction became feasible experimentally.

Quantum Teleportation of Optical Quantum Gates [PDF]
Physical Review Letters, 2003 We show that a universal set of gates for quantum computation with optics can be quantum teleported through the use of EPR entangled states, homodyne detection, and linear optics and squeezing operations conditioned on measurement outcomes. This scheme may be used for fault-tolerant quantum computation in any optical scheme (qubit or continuous ...
