Generalized speed and cost rate in transitionless quantum driving
Zhen-Yu Xu, Wen-Long You, Yu-Li Dong +2
Transitionless quantum driving, also known as counterdiabatic driving, is a unique shortcut technique to adiabaticity, enabling a fast-forward evolution to the same target quantum…
Phase transition of light in circuit QED lattices coupled to nitrogen-vacancy centers in diamond
Jia-Bin You, W. L. Yang, Zhen-Yu Xu +2
We propose a hybrid quantum architecture for engineering a photonicMott insulator-superfluid phase transition in a two-dimensional (2D) square lattice of a superconducting transmis…
Quantum interferometry with binary-outcome measurements in the presence of phase diffusion
X. M. Feng, G. R. Jin, W. Yang
Optimal measurement scheme with an efficient data processing is important in quantum-enhanced interferometry. Here we prove that for a general binary outcome measurement, the simpl…
Quantum speedup in a memory environment
Zhen-Yu Xu, Shunlong Luo, W. L. Yang +2
Memory (non-Markovian) effect is found to be able to accelerate quantum evolution [S. Deffner and E. Lutz, Phys. Rev. Lett. 111, 010402 (2013)]. In this work, for an atom in a stru…
Quantum-memory-assisted entropic uncertainty principle under noise
Z. Y. Xu, W. L. Yang, M. Feng
The measurement outcomes of two incompatible observables on a particle can be precisely predicted when it is maximally entangled with a quantum memory, as quantified recently [Natu…
Comparison of different measures for quantum discord under non-Markovian noise
Zhenyu Xu, Wanli Yang, Xing Xiao +1
Two geometric measures for quantum discord were recently proposed by Modi et al. [Phys. Rev. Lett. 104, 080501 (2010)] and Dakic et al. [Phys. Rev. Lett. 105, 190502 (2010)]. We st…
