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…
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…
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 inte…
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…
Atomic electron transitions of hydrogen-like atoms induced by gravitational waves
Bo-Hung Chen, Dah-Wei Chiou
As a realistic model of a quantum system of matter, this paper investigates the gravitational-wave effects on a hydrogen-like atom. By formulating the tetrad formalism of linearize…
Response of the Unruh-DeWitt detector in a gravitational wave background
Bo-Hung Chen, Dah-Wei Chiou
Applying the techniques of light-front quantization to quantize a scalar field in a monochromatic gravitational wave background, we manage to investigate the response of the Unruh-…
A unified view of curvature and torsion in metric-affine gauge theory of gravity through affine-vector bundles
Bo-Hung Chen, Dah-Wei Chiou
One of the most appealing results of metric-affine gauge theory of gravity is a close parallel between the Riemann curvature two-form and the Cartan torsion two-form: While the for…
Black holes in Einstein-Gauss-Bonnet gravity with a background of modified Chaplygin gas
Xiang-Qian Li, Bo Chen, Li-Li Xing
Supposing the existence of modified Chaplygin gas with the equation of state as a cosmic background, we obtain a static spherically-symmetric solution to the Einstein-…
Two-path interference of single-particle pulses measured by the Unruh-DeWitt-type quantum detector
Bo-Hung Chen, Tsung-Wei Chen, Dah-Wei Chiou
We study the two-path interference of single-particle pulses measured by the Unruh-DeWitt-type quantum detector, which itself is a quantum state as well as the incoming pulse, and…
Charged Lovelock black holes in the presence of dark fluid with a nonlinear equation of state
Xiang-Qian Li, Bo Chen, Li-li Xing
We consider a model that charged static spherically-symmetric black hole is surrounded by dark fluid with nonlinear equation of state . We find that the energy density…
An elementary proof and detailed investigation of the bulk-boundary correspondence in the generic two-band model of Chern insulators
Bo-Hung Chen, Dah-Wei Chiou
With the inclusion of arbitrary long-range hopping and (pseudo)spin-orbit coupling amplitudes, we formulate a generic model that can describe any two-dimensional two-band bulk insu…
An elementary rigorous proof of bulk-boundary correspondence in the generalized Su-Schrieffer-Heeger model
Bo-Hung Chen, Dah-Wei Chiou
We generalize the Su-Schrieffer-Heeger (SSH) model with the inclusion of arbitrary long-range hopping amplitudes, providing a simple framework to investigate arbitrary adiabatic de…
