Quantum versus Classical Regime in Circuit Quantum Acoustodynamics
Gang-hui Zeng, Yang Zhang, Aleksey N. Bolgar +8
We experimentally study a circuit quantum acoustodynamics system, which consists of a superconducting artificial atom, coupled to both a two-dimensional surface acoustic wave reson…
Entanglement of Two Jaynes-Cummings Atoms In Single Excitation Space
Ya Yang, Yan Liu, Jing Lu +1
We study the entanglement dynamics of two atoms coupled to their own Jaynes-Cummings cavities in single-excitation space. Here we use the concurrence to measure the atomic entangle…
Measurement-device-independent quantum key distribution of multiple degrees of freedom of a single photon
Yu-Fei Yan, Lan Zhou, Wei Zhong +1
Measurement-device-independent quantum key distribution (MDI-QKD) provides us a powerful approach to resist all attacks at detection side. Besides the unconditional security, peopl…
Ancilla-assisted frequency estimation under phase covariant noises with Greenberger-Horne-Zeilinger states
Rui-Jie Cai, Wei Zhong, Lan Zhou +1
It has been demonstrated that the optimal sensitivity achievable with Greenberger-Horne-Zeilinger states is the same as that with uncorrelated probes in the frequency estimation in…
Quantum-enhanced interferometry with asymmetric beam splitters
Wei Zhong, Fan Wang, Lan Zhou +2
In this paper, we investigate the phase sensitivities in two-path optical interferometry with asymmetric beam splitters. Here, we present the optimal conditions for the transmissio…
Double-port measurements for robust quantum optical metrology
Wei Zhong, Lan Zhou, Yu-Bo Sheng
It has been proposed and demonstrated that path-entangled Fock states (PEFSs) are robust against photon loss over NOON states [S. D. Huver \emph{et al.}, Phys. Rev. A \textbf{78},…
