Two-level approximation of transmons in quantum quench experiments
H. S. Yan, Yong-Yi Wang, S. K. Zhao +7
Quantum quench is a typical protocol in the study of nonequilibrium dynamics of quantum many-body systems. Recently, a number of experiments with superconducting transmon qubits ar…
Quantum simulation of topological zero modes on a 41-qubit superconducting processor
Yun-Hao Shi, Yu Liu, Yu-Ran Zhang +21
Quantum simulation of different exotic topological phases of quantum matter on a noisy intermediate-scale quantum (NISQ) processor is attracting growing interest. Here, we develop…
Observation of critical phase transition in a generalized Aubry-André-Harper model on a superconducting quantum processor with tunable couplers
Hao Li, Yong-Yi Wang, Yun-Hao Shi +15
Quantum simulation enables study of many-body systems in non-equilibrium by mapping to a controllable quantum system, providing a new tool for computational intractable problems. H…
Quantum simulation of Hawking radiation and curved spacetime with a superconducting on-chip black hole
Yun-Hao Shi, Run-Qiu Yang, Zhongcheng Xiang +10
Hawking radiation is one of the quantum features of a black hole that can be understood as a quantum tunneling across the event horizon of the black hole, but it is quite difficult…
Probing Operator Spreading via Floquet Engineering in a Superconducting Circuit
S. K. Zhao, Zi-Yong Ge, Zhongcheng Xiang +16
Operator spreading, often characterized by out-of-time-order correlators (OTOCs), is one of the central concepts in quantum many-body physics. However, measuring OTOCs is experimen…
Coherent population transfer between weakly-coupled states in a ladder-type superconducting qutrit
H. K. Xu, W. Y. Liu, G. M. Xue +9
Stimulated Raman adiabatic passage (STIRAP) offers significant advantages for coherent population transfer between un- or weakly-coupled states and has the potential of realizing e…
Quantum Phase Diffusion in a Small Underdamped Josephson Junction
H. F. Yu, X. B. Zhu, Z. H. Peng +8
Quantum phase diffusion in a small underdamped Nb/AlO/Nb junction ( 0.4 m) is demonstrated in a wide temperature range of 25-140 mK where macroscopic quantum tunne…
Quantum and classical resonant escapes of a strongly-driven Josephson junction
H. F. Yu, X. B. Zhu, Z. H. Peng +9
The properties of phase escape in a dc SQUID at 25 mK, which is well below quantum-to-classical crossover temperature , in the presence of strong resonant ac driving have b…
