Observation of a symmetry-protected topological time crystal with superconducting qubits
Xu Zhang, Wenjie Jiang, Jinfeng Deng +15
We report the observation of a symmetry-protected topological time crystal, which is implemented with an array of programmable superconducting qubits. Unlike the time crystals repo…

Synthesizing five-body interaction in a superconducting quantum circuit
Ke Zhang, Hekang Li, Pengfei Zhang +10
Synthesizing many-body interaction Hamiltonian is a central task in quantum simulation. However, it is challenging to synthesize interactions including more than two spins. Borrowi…

Metrological characterisation of non-Gaussian entangled states of superconducting qubits
Kai Xu, Yu-Ran Zhang, Zheng-Hang Sun +12
Multipartite entangled states are significant resources for both quantum information processing and quantum metrology. In particular, non-Gaussian entangled states are predicted to…
