Verification of a resetting protocol for an uncontrolled superconducting qubit
Ming Gong, Feihu Xu, Zheng-Da Li +20
Quantum resetting protocols allow a quantum system to be sent to a state in the past by making it interact with quantum probes when neither the free evolution of the system nor the…
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…
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…
