Multipartite Einstein-Podolsky-Rosen steering and genuine tripartite entanglement with optical networks
Seiji Armstrong, Meng Wang, Run Yan Teh +6
The Einstein-Podolsky-Rosen (EPR) paradox established a link between entanglement and nonlocality in quantum mechanics. EPR steering is the nonlocality associated with the EPR para…
Experimental entanglement-assisted quantum delayed-choice experiment
Tao Xin, Hang Li, Bi-Xue Wang +1
The puzzling properties of quantum mechanics, wave-particle duality, entanglement and superposition, were dissected experimentally at past decades. However, hidden-variable (HV) mo…
Experimental Estimation of Average Fidelity of a Clifford Gate on a 7-qubit Quantum Processor
Dawei Lu, Hang Li, Denis-Alexandre Trottier +8
Quantum gates in experiment are inherently prone to errors that need to be characterized before they can be corrected. Full characterization via quantum process tomography is impra…
Classical-driving-assisted quantum speed-up
Ying-Jie Zhang, Wei Han, Yun-Jie Xia +2
We propose a method of accelerating the speed of evolution of an open system by an external classical driving field for a qubit in a zero-temperature structured reservoir. It is sh…
Entropic uncertainty relations for multiple measurements
Shang Liu, Liang-Zhu Mu, Heng Fan
We present the entropic uncertainty relations for multiple measurement settings in quantum mechanics. Those uncertainty relations are obtained for both cases with and without the p…
Operation triggered quantum clock synchronization
Jie-Dong Yue, Yu-Ran Zhang, Heng Fan
We present a novel quantum clock synchronization(QCS) scheme of multiple parties which uses operation as the trigger to start the evolution of the initial state, where existing QCS…
Optimal limits of cavity optomechanical cooling in the strong coupling regime
Yong-Chun Liu, Yu-Feng Shen, Qihuang Gong +1
Laser cooling of mesoscopic mechanical resonators is of great interest for both fundamental studies and practical applications. We provide a general framework to describe the cavit…
The Fidelity and Trace Norm Distances for Quantifying Coherence
Lian-He Shao, Zhengjun Xi, Heng Fan +1
We investigate the coherence measures induced by fidelity and trace norm, based on the recent proposed coherence quantification in [Phys. Rev. Lett. 113, 140401, 2014]. We show tha…
One-Way Deficit of Two Qubit X States
Yao-Kun Wang, Naihuan Jing, Shao-Ming Fei +3
Quantum deficit originates in questions regarding work extraction from quantum systems coupled to a heat bath [Phys. Rev. Lett. 89, 180402 (2002)]. It links quantum correlations wi…
Secure continuous variable quantum teleportation and Einstein-Podolsky-Rosen steering
Qiongyi He, Laura Rosales-Zarate, Gerardo Adesso +1
We investigate the resources needed for secure teleportation of coherent states. We extend continuous variable teleportation to include quantum tele-amplification protocols, that a…
