Entropic Uncertainty Principle and Information Exclusion Principle for multiple measurements in the presence of quantum memory
Jun Zhang, Yang Zhang, Chang-shui Yu
The Heisenberg uncertainty principle shows that no one can specify the values of the non-commuting canonically conjugated variables simultaneously. However, the uncertainty relatio…
Weak measurement with a coherent state pointer and its implementation in optomechanical system
Gang Li, Ming-Yong Ye, Xiu-Min Lin +1
Weak measurement with a coherent state pointer and in combination with an orthogonal postselection can lead to a surprising amplification effect, and we give a fire-new physical me…
Precision metrology of weak measurement with thermal state pointer
Gang Li, Li-Bo Chen, Tao Wang +2
Quantum metrology is being gradually studied for weak measurement systems. For weak measurement systems with thermal state pointer, we find that in the displacement space correspon…
Controlling photon transport in the single-photon weak-coupling regime of cavity optomechanics
Wen-Zhao Zhang, Jiong Cheng, Jing-Yi Liu +1
We study the photon statistics properties of few-photon transport in an optomechanical system where an optomechanical cavity couples to two empty cavities. By analytically deriving…
Robust state transfer with high fidelity in spin-1/2 chains by Lyapunov control
Z. C. Shi, X. L. Zhao, X. X. Yi
Based on the Lyapunov control, we present a scheme to realize state transfer with high fidelity by only modulating the boundary spins in a quantum spin-1/2 chain. Recall that the c…
Scalable quantum information transfer between nitrogen-vacancy-center ensembles
Feng-Yang Zhang, Chui-Ping Yang, He-Shan Song
We propose an architecture for realizing quantum information transfer (QIT). In this architecture, a LC circuit is used to induce the necessary interaction between flux qubits, eac…
