Quantum networks generation based on four-wave mixing
Yin Cai, Jingliang Feng, Hailong Wang +4
We present a scheme to realize versatile quantum networks by cascading several four-wave mixing (FWM) processes in warm rubidium vapors. FWM is an efficient nonlinear pro…
Atomic quantum memory for multimode frequency combs
Z. Zheng, O. Mishina, N. Treps +1
We propose a Raman quantum memory scheme that uses several atomic ensembles to store and retrieve the multimode highly entangled state of an optical quantum frequency comb, such as…
Past quantum state analysis of the photon number evolution in a cavity
Théo Rybarczyk, Stefan Gerlich, Bruno Peaudecerf +8
A quantum system can be monitored through repeated interactions with meters, followed by their detection. The state of the system at time t is thus conditioned on the information o…
Full multipartite entanglement of frequency comb Gaussian states
S. Gerke, J. Sperling, W. Vogel +4
An analysis is conducted of the multipartite entanglement for Gaussian states generated by the parametric down-conversion of a femtosecond frequency comb. Using a recently introduc…
Optimization of networks for measurement-based quantum computation
G. Ferrini, J. Roslund, F. Arzani +3
This work introduces optimization strategies to continuous variable measurement based quantum computation (MBQC) at different levels. We provide a recipe for mitigating the effects…
Witnessing single-photon entanglement with local homodyne measurements: analytical bounds and robustness to losses
Melvyn Ho, Olivier Morin, Jean-Daniel Bancal +3
Single-photon entanglement is one of the primary resources for quantum networks, including quantum repeater architectures. Such entanglement can be revealed with only local homodyn…
