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…
