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…
Observation of energy resolved many-body localization
Qiujiang Guo, Chen Cheng, Zheng-Hang Sun +10
Many-body localization (MBL) describes a quantum phase where an isolated interacting system subject to sufficient disorder displays non-ergodic behavior, evading thermal equilibriu…
Experimental demonstration of entanglement-enabled universal quantum cloning in a circuit
Zhen-Biao Yang, Pei-Rong Han, Xin-Jie Huang +6
No-cloning theorem forbids perfect cloning of an unknown quantum state. A universal quantum cloning machine (UQCM), capable of producing two copies of any input qubit with the opti…
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…
Observation of multi-component atomic Schrödinger cat states of up to 20 qubits
Chao Song, Kai Xu, Hekang Li +13
We report on deterministic generation of 18-qubit genuinely entangled Greenberger-Horne-Zeilinger (GHZ) state and multi-component atomic Schrödinger cat states of up to 20 qubits o…
Deterministic entanglement swapping in a superconducting circuit
Wen Ning, Xin-Jie Huang, Pei-Rong Han +8
Entanglement swapping, the process to entangle two particles without coupling them in any way, is one of the most striking manifestations of the quantum-mechanical nonlocal charact…
