Observation of Non-Markovian Evolution of Tripartite Quantum Steering
Yan Wang, Shao-qi Lin, Rui-qi Shen +6
The memory effects in open quantum systems can induce information backflow and revive quantum correlations, thereby providing a powerful way to protect and recover useful quantum r…
Observation of feedback-directed quantum dynamics in large-scale quantum processors
Ruizhe Shen, Ching Hua Lee
Programmable quantum hardware provides an emerging platform for exploring and controlling non-unitary quantum dynamics through measurement-based operations. In this work, we introd…
Digital Simulation of Non-Hermitian Knotted Bands on Quantum Hardware
Truman Yu Ng, Yuzhu Wang, Wei Jie Chan +3
Knots and links represent a fundamental motif of non-local connectivity that permeates the physical sciences from string theory to protein folds. While spectral braiding has been e…
Benchmarking Quantum Solvers in Noisy Digital Simulations for Financial Portfolio Optimization
Ruizhe Shen, Zichang Hao, Ching Hua Lee
In this work, we benchmark two prominent quantum algorithms: Quantum Imaginary-Time Evolution (QITE) and the Quantum Approximate Optimization Algorithm (QAOA) for obtaining the gro…
Circuit structure-preserving error mitigation for High-Fidelity Quantum Simulations
Ruizhe Shen, Tianqi Chen, Ching Hua Lee
Developing methods to accurately characterize and mitigate the impact of noise is crucial for enhancing the fidelity of quantum simulations on Noisy Intermediate-Scale Quantum (NIS…
Robust Simulations of Many-Body Symmetry-Protected Topological Phase Transitions on a Quantum Processor
Ruizhe Shen, Tianqi Chen, Bo Yang +2
Topology and symmetry play critical roles in characterizing quantum phases of matter. Recent advancements have unveiled symmetry-protected topological (SPT) phases in many-body sys…
