Thermodynamics and Fluctuations in Quantum Heat Engines under Reservoir Squeezing
Yang Xiao, Dehua Liu, Jizhou He +3
We investigate the thermodynamics and fluctuations of a finite-time quantum Otto engine alternatively driven by a hot squeezed and a cold thermal reservoir. We show that reservoir…
Bounded light cone and robust topological order out of equilibrium
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +3
The ground state degeneracy of topologically ordered gapped Hamiltonians is the bedrock for self-correcting quantum memories, which are unfortunately not stable away from equilibri…
Protecting topological order by dynamical localization
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +3
As a prototype model of topological quantum memory, two-dimensional toric code is genuinely immune to generic local static perturbations, but fragile at finite temperature and also…
Super-additivity of quantum-correlating power
Xueyuan Hu, Heng Fan, D. L. Zhou +1
We prove that, when two local quantum channels are used paralleled, the quantum-correlating power (QCP) of the composed channel is no less than the sum of QCP of the two channels.…
Quantum-correlating power of local quantum channels
Xueyuan Hu, Heng Fan, D. L. Zhou +1
Quantum correlation can be created by local operations from a classically correlated state. We define quantum-correlating power (QCP) of a local quantum channel as the maximum amou…
Necessary and sufficient conditions for local creation of quantum correlation
Xueyuan Hu, Heng Fan, D. L. Zhou +1
Quantum correlation can be created by a local operation from some initially classical states. We prove that the necessary and sufficient condition for a local trace-preserving chan…
Conditions on local operations to create quantum correlation
Xueyuan Hu, Heng Fan, Duan-Lu Zhou +1
We prove the condition for local trace-preserving channels to create quantum correlation from initially classical states. For two-qubit states, the necessary and sufficient conditi…
Quantum correlations in spin models
Guo-Feng Zhang, Heng Fan, Ai-Ling Ji +3
Bell nonlocality, entanglement and nonclassical correlations are different aspects of quantum correlations for a given state. There are many methods to measure nonclassical correla…
Maximally entangled state can be a mixed state
Zong-Guo Li, Ming-Jing Zhao, Shao-Ming Fei +2
We find that the mixed maximally entangled states exist and prove that the form of the mixed maximally entangled states is unique in terms of the entanglement of formation. Moreove…
