Gain on ground state of quantum system for truly symmetry
Bing-Bing Liu, Shi-Lei Su
For a truly -symmetric quantum system, the conventional non-Hermitian Hamiltonian is , where and …
Using PT-symmetric Qubits to Break the Tradeoff Between Fidelity and the Degree of Quantum Entanglement
B. -B. Liu, Shi-Lei Su, Y. -L. Zuo +4
A noteworthy discovery is that the minimal evolution time is smaller for parity-time () symmetric systems compared to Hermitian setups. Moreover, there is a significa…
Experimental Verification of Demon-Involved Fluctuation Theorems
L. -L. Yan, J. -T. Bu, Q. Zeng +8
The limit of energy saving in the control of small systems has recently attracted much interest due to the concept refinement of the Maxwell demon. Inspired by a newly proposed set…
One-step implementation of nonadiabatic geometric fSim gate in superconducting circuits
M. -R. Yun, Zheng Shan, Li-Li Sun +3
Due to its significant application in reducing algorithm depth, fSim gates have attracted a lot of attention. However, during the implementation of quantum gates, fluctuations in c…
