Observation of Two-Vertex Four-Dimensional Spin Foam Amplitudes with a 10-qubit Superconducting Quantum Processor
Pengfei Zhang, Zichang Huang, Chao Song +8
Quantum computers are an increasingly hopeful means for understanding large quantum many-body systems bearing high computational complexity. Such systems exhibit complex evolutions…
Scalable evaluation of quantum-circuit error loss using Clifford sampling
Zhen Wang, Yanzhu Chen, Zixuan Song +6
A major challenge in developing quantum computing technologies is to accomplish high precision tasks by utilizing multiplex optimization approaches, on both the physical system and…
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…
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…
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…
