Code-space recovery for sample-based quantum diagonalization beyond native symmetry constraints
Byeongyong Park, Sanha Kang, Doyeol Ahn +1
Quantum algorithms that sample basis states and diagonalize a Hamiltonian in their span depend on repairing noisy measurement outcomes, using a constraint native to the target prob…
Cluster-Adaptive Sample-Based Quantum Diagonalization for Strongly Correlated Systems
Byeongyong Park, Sanha Kang, Jongseok Seo +3
Sample-based quantum diagonalization (SQD) is a hybrid quantum-classical algorithm for estimating ground-state energies in electronic-structure calculations. It uses a quantum proc…
Reducing T-Count in quantum string matching algorithm using relative-phase Fredkin gate
Byeongyong Park, Hansol Noh, Doyeol Ahn
The string-matching problem, ubiquitous in computer science, can significantly benefit from quantum algorithms due to their potential for greater efficiency compared to classical a…
Non-Reciprocity in Photon Polarization based on direction of polarizer under Gravitational Fields
Hansol Noh, Paul M. Alsing, Warner A. Miller +1
Unification of gravity with quantum mechanics is still a terra incognita. Photon polarization measurements offer a unique window for probing the interaction between these two funda…
Non-Markovian cost function for quantum error mitigation with Dirac Gamma matrices representation
Doyeol Ahn
In this study, we explore the non-Markovian cost function for quantum error mitigation (QEM) and the representation of two-qubit operators using Dirac Gamma matrices, central to th…
