Generation of pulsed bipartite entanglement using four-wave mixing
Quentin Glorieux, Jeremy B. Clark, Neil V. Corzo +1
Using four-wave mixing in a hot atomic vapor, we generate a pair of entangled twin beams in the microsecond pulsed regime near the D1 line of Rb, making it compatible with c…
Efficient single-spatial-mode periodically-poled KTiOPO_4 waveguide source for high-dimensional entanglement-based quantum key distribution
Tian Zhong, Franco N. C. Wong, Alessandro Restelli +1
We demonstrate generation of high-purity photon pairs at 1560 nm in a single spatial mode from a periodically-poled KTiOPO_4 (PPKTP) waveguide. With nearly lossless spectral filter…
Deterministic Photon Pairs via Coherent Optical Control of a Single Quantum Dot
Harishankar Jayakumar, Ana Predojević, Tobias Huber +3
The strong confinement of semiconductor excitons in a quantum dot gives rise to atom-like behavior. The full benefit of such a structure is best observed in resonant excitation whe…
Gradient echo memory in an ultra-high optical depth cold atomic ensemble
B. M. Sparkes, J. Bernu, M. Hosseini +6
Quantum memories are an integral component of quantum repeaters - devices that will allow the extension of quantum key distribution to communication ranges beyond that permissible…
Efficiency vs. multi-photon contribution test for quantum dots
Ana Predojevic, Miroslav Jezek, Tobias Huber +5
The development of linear quantum computing within integrated circuits demands high quality semiconductor single photon sources. In particular, for a reliable single photon source…
Emergence and Frustration of Magnetic Order with Variable-Range Interactions in a Trapped Ion Quantum Simulator
R. Islam, C. Senko, W. C. Campbell +7
Frustration, or the competition between interacting components of a network, is often responsible for the complexity of many body systems, from social and neural networks to protei…
