Quantum speedup dynamics process in Schwarzschild space-time
Kai Xu, Han-Jie Zhu, Guo-Feng Zhang +2
Quantum speed limit time (QSLT) can be used to characterize the intrinsic minimal time interval for a quantum system evolving from an initial state to a target state. We investigat…
Vortex-Meissner phase transition induced by two-tone-drive-engineered artificial gauge potential in the fermionic ladder constructed by superconducting qubit circuits
Yan-Jun Zhao, Xun-Wei Xu, Hui Wang +2
We propose to periodically modulate the onsite energy via two-tone drives, which can be furthermore used to engineer artificial gauge potential. As an example, we show that the fer…
Synthesizing three-body interaction of spin chirality with superconducting qubits
Wuxin Liu, Wei Feng, Wenhui Ren +2
Superconducting qubits provide a competitive platform for quantum simulation of complex dynamics that lies at the heart of quantum many-body systems, because of the flexibility and…
Probing the dynamical phase transition with a superconducting quantum simulator
Kai Xu, Zheng-Hang Sun, Wuxin Liu +9
Non-equilibrium quantum many-body systems, which are difficult to study via classical computation, have attracted wide interest. Quantum simulation can provide insights into these…
Generation and controllable switching of superradiant and subradiant states in a 10-qubit superconducting circuit
Zhen Wang, Hekang Li, Wei Feng +9
Superradiance and subradiance concerning enhanced and inhibited collective radiation of an ensemble of atoms have been a central topic in quantum optics. However, precise generatio…
Quantum dynamical speedup in correlated noisy channels
Kai Xu, Guo-Feng Zhang, Wu-Ming Liu
The maximal evolution speed of a quantum system can be represented by quantum speed limit time (QSLT).We investigate QSLT of a two-qubit system passing through a correlated channel…
