We propose a potentially practical scheme for realization of two-mode squeezed state with respect to two distant nitrogen-vacancy center ensembles coupled to two interconnected mec…
The transport character of quantum state in one-dimensional coupled-cavity-arrays: effect of the number of photons and entanglement degree
Shao-Qiang Ma, Guo-Feng Zhang
The transport properties of the photons injected into one-dimensional coupled-cavity-arrays (CCAs) are studied. It is found that the number of photons cannot change the evolution c…
Non-Markovian coherent feedback control of quantum dot systems

We propose to demonstrate nonreciprocal conversion between microwave and optical photons in an electro-optomechanical system where a microwave mode and an optical mode are coupled…
Loss-tolerant measurement-device-independent quantum random number generation
Zhu Cao, Hongyi Zhou, Xiongfeng Ma
Quantum random number generators (QRNGs) output genuine random numbers based upon the uncertainty principle. A QRNG contains two parts in general --- a randomness source and a read…
