Stretched Exponential Scaling of Parity-Restricted Energy Gaps in a Random Transverse-Field Ising Model
G. -X. Tang, J. -Z. Zhuang, L. -M. Duan +1
The success of a quantum annealing algorithm requires a polynomial scaling of the energy gap. Recently it was shown that a two-dimensional transverse-field Ising model on a square…
Hardware-efficient variational quantum algorithm in trapped-ion quantum computer
J. -Z. Zhuang, Y. -K. Wu, L. -M. Duan
We study a hardware-efficient variational quantum algorithm ansatz tailored for the trapped-ion quantum simulator, HEA-TI. We leverage programmable single-qubit rotations and globa…
Dynamical phase transitions of information flow in random quantum circuits
J. -Z. Zhuang, Y. -K. Wu, L. -M. Duan
We study how the information flows in many-body dynamics governed by random quantum circuits and discover a rich set of dynamical phase transitions in this information flow. The ph…
Phase-transition-like behavior in information retrieval of a quantum scrambled random circuit system
J. -Z. Zhuang, Y. -K. Wu, L. -M. Duan
Information in a chaotic quantum system will scramble across the system, preventing any local measurement from reconstructing it. The scrambling dynamics is key to understanding a…
