Nonorthogonal-state erasure as the resource behind apparent second-law violations
Xinshu Xia, Hui Hui Qin, Yu-Han Ma +2
Perfect deterministic distinguishing of nonorthogonal quantum states is forbidden by the linear and unitary structure of quantum mechanics. It has often been assumed that, if such…
Minimal Energy Cost to Initialize a Quantum Bit with Tolerable Error
Yu-Han Ma, Jin-Fu Chen, C. P. Sun +1
Landauer's principle imposes a fundamental limit on the energy cost to perfectly initialize a classical bit, which is only reached under the ideal operation with infinite-long time…
Self-consistency of optimizing finite-time Carnot engines with the low-dissipation model
Yu-Han Ma, C. P. Sun, Hui Dong
The efficiency at the maximum power (EMP) for finite-time Carnot engines established with the low-dissipation model, relies significantly on the assumption of the inverse proportio…
Directional quantum random walk induced by coherence
Jin-Fu Chen, Yu-Han Ma, Chang-Pu Sun
Quantum walk (QW), which is considered as the quantum counterpart of the classical random walk (CRW), is actually the quantum extension of CRW from the single-coin interpretation.…
Optimal operating protocol to achieve efficiency at maximum power of heat engines
Yu-Han Ma, Dazhi Xu, Hui Dong +1
The efficiency at maximum power has been investigated extensively, yet the practical control scheme to achieve it remains elusive. We fill such gap with a stepwise Carnot-like cycl…
Universal constraint for efficiency and power of a low-dissipation heat engine
Yu-Han Ma, Dazhi Xu, Hui Dong +1
The constraint relation for efficiency and power is crucial to design optimal heat engines operating within finite time. We find a universal constraint between efficiency and outpu…
Non-thermal radiation of black hole off canonical typicality
Yu-Han Ma, Qing-Yu Cai, Hui Dong +1
We study the Hawking radiation of black holes by considering the canonical typicality. For the universe consisting of black holes and their outer part, we directly obtain a non-the…
Decoherence of Macroscopic Objects from Relativistic Effect
G. H. Dong, Y. H. Ma, J. F. Chen +2
We study how the decoherence of macroscopic objects is induced intrisinically by relativistic effect. With the degree of freedom of center of mass (CM) characterizing the collectiv…
Quantum thermodynamic cycle with quantum phase transition
Yu-Han Ma, Shan-He Su, Chang-Pu Sun
With the Lipkin-Meshkov-Glick (LMG) model as an illustration, we construct a thermodynamic cycle composed of two isothermal processes and two isomagnetic field processes and study…
The heat and work of quantum thermodynamic processes with quantum coherence
Shan-He Su, Jin-Fu Chen, Yu-Han Ma +2
Energy is often partitioned into heat and work by two independent paths corresponding to the change in the eigenenergies or the probability distributions of a quantum system. The d…
Quantum sensing of rotation velocity based on transverse field Ising model
Y. H. Ma, C. P. Sun
We study a transverse-field Ising model (TFIM) in a rotational reference frame. We find that the effective Hamiltonian of the TFIM of this system depends on the system's rotation v…
