Feedback Ansatz for Adaptive-Feedback Quantum Metrology Training with Machine Learning
Yi Peng, Heng Fan
It is challenging to construct metrology schemes which harness quantum features such as entanglement and coherence to surpass the standard quantum limit. We propose an ansatz for d…
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…
A Universal Quantum Computing Virtual Machine
Qian-Tan Hong, Zi-Yong Ge, Wen Wang +8
A medium-scale quantum computer with full universal quantum computing capability is necessary for various practical aims and testing applications. Here we report a 34-qubit quantum…
Demonstration of irreversibility and dissipation relation of thermodynamics with a superconducting qubit
Xue-Yi Guo, Yi Peng, Changnan Peng +6
We investigate experimentally the relation between thermodynamical irreversibility and dissipation on a superconducting Xmon qubit. This relation also implies the second law and th…
