Genuine 12-qubit entanglement on a superconducting quantum processor
Ming Gong, Ming-Cheng Chen, Yarui Zheng +20
We report the preparation and verification of a genuine 12-qubit entanglement in a superconducting processor. The processor that we designed and fabricated has qubits lying on a 1D…
Dephasing-insensitive quantum information storage and processing with superconducting qubits
Qiujiang Guo, Shi-Biao Zheng, Jianwen Wang +11
A central task towards building a practical quantum computer is to protect individual qubits from decoherence while retaining the ability to perform high-fidelity entangling gates…
Observation of dynamical quantum phase transition by a superconducting qubit simulation
Xue-Yi Guo, Chao Yang, Yu Zeng +7
A dynamical quantum phase transition can occur during time evolution of sudden quenched quantum systems across a phase transition. It corresponds to the nonanalytic behavior at a c…
Experimental Realization of Nonadiabatic Shortcut to Non-Abelian Geometric Gates
Tongxing Yan, Bao-Jie Liu, Kai Xu +10
When a quantum system is driven adiabatically through a parametric cycle in a degenerate Hilbert space, the state would acquire a non-Abelian geometric phase, which is stable and f…
