Universal Speed Limit in a Far-from-Equilibrium Bose Gas: Symmetry and Dynamical Decoherence
Jun-Cheng Liang, Bo Chen
Predicting universal transport coefficients in far-from-equilibrium quantum systems remains a fundamental challenge. A paradigmatic example is the non-thermal fixed point (NTFP) of…
Quantum circuit synthesis for the preparation of arbitrary and highly sparse mixed quantum states
Bo-Hung Chen, Dah-Wei Chiou, Jie-Hong Roland Jiang
This paper addresses the challenge of preparing mixed quantum states -- both arbitrary states in general and highly sparse ones in particular -- an area that has received far less…
Adiabatic Quantum Simulation of the Topological Su--Schrieffer--Heeger--Hubbard Model
Ssu-Yi Chen, Bo-Hung Chen, Dah-Wei Chiou +1
We develop an adiabatic quantum simulation framework on gate-based quantum computers to probe topological signatures of the one-dimensional fermionic Su--Schrieffer--Heeger--Hubbar…
Error-Tolerant Quantum State Discrimination: Optimization and Quantum Circuit Synthesis
Chien-Kai Ma, Bo-Hung Chen, Tian-Fu Chen +2
We develop error-tolerant quantum state discrimination(QSD) strategies that maintain reliable performance under moderate noise. Two complementary approaches are proposed: CrossQSD,…
Enhanced Quantum Circuit Cutting Framework for Sampling Overhead Reduction
Po-Hung Chen, Dah-Wei Chiou, Bo-Hung Chen +1
The recently developed quantum circuit cutting technique greatly extends the capabilities of current noisy intermediate-scale quantum (NISQ) hardware. However, it introduces substa…
Demonstration of Scully-Drühl-type quantum erasers on quantum computers
Bo-Hung Chen, Dah-Wei Chiou, Hsiu-Chuan Hsu
We present a novel quantum circuit that genuinely implements the Scully-Drühl-type delayed-choice quantum eraser, where the two recorders of the which-way information directly int…
