Mutual information across the commensurate--incommensurate crossover and near the Kosterlitz--Thouless point of the spin- -- Heisenberg chain
Wuttichai Pankeaw, Pruet Kalasuwan
What quantum mutual information adds to conventional correlation functions is often unclear. We study the spin-1/2 - Heisenberg chain, using DMRG on infinite chains and p…
Three-Photon and Hybrid Coherent-Fock Interference in a Two-Phase Six-Port Mach-Zehnder Interferometer
P. O. Amadi, P. Pewkhom, N. Sitpathom +5
We present a unified theoretical analysis of three-photon quantum interference in a Six-Port Mach-Zehnder Interferometer (6p-MZI) constructed from two cascaded tritters, with two i…
Hardware-Free Polarization Stabilization for Measurement-Device-Independent Quantum Key Distribution via Correlated Twirling
Papon Pewkhom, Nattee Jeennugool, Norshamsuri Ali +3
Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) provides unconditional security against detector vulnerabilities, but its practical deployment is severely hindere…
Entanglement signature of fully and partially dimerized phases in frustrated spin chains
Wuttichai Pankeaw, Teparksorn Pengpan, Pruet Kalasuwan
The von Neumann entanglement entropy of exact valence-bond ground states is studied in two frustrated one-dimensional spin chains: the spin-1/2 Majumdar-Ghosh (MG) model and the sp…
Fisher Information Measures under Lattice Combined Paul Trap
Precious Ogbonda Amadi, Paphon Pewkhom, Pruet Kalasuwan +3
We examine how the informational properties of a confined single ion response in a Paul trap modified by optical-lattice. We focus on the ground and first excited motional states a…
Quantum Phase Estimation Algorithm for Finding Polynomial Roots
Theerapat Tansuwannont, Surachate Limkumnerd, Sujin Suwanna +1
Quantum algorithm is an algorithm for solving mathematical problems using quantum systems encoded as information, which is found to outperform classical algorithms in some specific…
Calculating Unknown Eigenvalues with a Quantum Algorithm
Xiao-Qi Zhou, Pruet Kalasuwan, Timothy C. Ralph +1
Quantum algorithms are able to solve particular problems exponentially faster than conventional algorithms, when implemented on a quantum computer. However, all demonstrations to d…
Adding control to arbitrary unknown quantum operations
Xiao-Qi Zhou, Timothy C. Ralph, Pruet Kalasuwan +4
While quantum computers promise significant advantages, the complexity of quantum algorithms remains a major technological obstacle. We have developed and demonstrated an architect…
A simple scheme for expanding photonic cluster states for quantum information
Pruet Kalasuwan, Gabriel Mendoza, Anthony Laing +6
We show how an entangled cluster state encoded in the polarization of single photons can be straightforwardly expanded by deterministically entangling additional qubits encoded in…
