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…
Simultaneous excitation of two noninteracting atoms with time-frequency correlated photon pairs in a superconducting circuit
Wenhui Ren, Wuxin Liu, Chao Song +9
Here we report the first observation of simultaneous excitation of two noninteracting atoms by a pair of time-frequency correlated photons in a superconducting circuit. The strong…
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…
