Bound-state-mediated remote charging of a quantum battery
Jian-Jian Cheng, Hai-Bo Qiu, Lin Zhang +1
Remote charging of a quantum battery (QB) is hindered by radiative leakage of the excitation into the photonic environment that acts as a mediator for energy transfer. We consider…
Evolution-Level Quantum Optimal Control of Single-Qubit Gates with Physics-Informed Neural Networks
Yao Du, Jian-Jian Cheng, Lin Zhang +2
Quantum gate design is often represented as pulse optimization, although the physical object that implements a gate is the full controlled evolution generated by the pulse. Here we…
Diversity of Superradiant Phase Transitions in the Bose-Fermi System under Tight-Binding Model in the Weak-Coupling Regime
Xing Su, Jian-Jian Cheng, Lin Zhang
We present a comprehensive analysis of the dynamic diversity associated with superradiant phase transitions within a one-dimensional tight-binding electronic chain that is intrinsi…
Implementing conventional and unconventional nonadiabatic geometric quantum gates via SU(2) transformations
Jian-jian Cheng, Lin Zhang
We propose a simple but versatile protocol to engineer time-dependent Hamiltonians inversely for geometric quantum computation. By utilizing SU(2) transformation, a speedup goal on…
