Comment on "Landau Levels and Riemann Zeros"

Mi-Ra Hwang, Eylee Jung, MuSeong Kim +1

Sierra and Townsend (ST) [1] showed that the ``absorption spectrum'' model of Connes [2] arises as the lowest-Landau-level (LLL) limit of a charged particle in crossed electric and…

Eigenvalue-by-Eigenvalue Comparison of a Sierra--Rodríguez-Laguna-Type Spectrum with the Riemann Zeros

Mi-Ra Hwang, Eylee Jung, MuSeong Kim +1

We study the self-adjoint extension of the Sierra--Rodríguez-Laguna (SR) -type Hamiltonian . Its discrete spectrum is fixed by the equation $\mathrm{Re}\!\le…

Feynman Propagator of the Arthurs-Kelly system at the Planck Scale

Mi-Ra Hwang, Eylee Jung, MuSeong Kim +1

The non-relativistic quantum mechanics with a generalized uncertainty principle (GUP) is examined in the Arthurs-Kelly system. The Feynman propagator for this system is exactly der…

A Simple Model of Superconductors: Insights from Free Fermion and Boson Gases

Mi-Ra Hwang, Eylee Jung, MuSeong Kim +1

Superconductors at temperatures below the critical temperature can be modeled as a mixture of Fermi and Bose gases, where the Fermi gas consists of conduction electrons and t…

Euclidean time method in Generalized Eigenvalue Equation

Mi-Ra Hwang, Eylee Jung, Museong Kim +1

We develop the Euclidean time method of the variational quantum eigensolver for solving the generalized eigenvalue equation , where and are h…

Average Rényi Entropy of a Subsystem in Random Pure State

MuSeong Kim, Mi-Ra Hwang, Eylee Jung +1

In this paper we examine the average Rényi entropy of a subsystem when the whole composite system is a random pure state. We assume that the Hilbert space dimensions…

Scrambling and Quantum Teleportation

MuSeong Kim, Mi-Ra Hwang, Eylee Jung +1

Scrambling is a concept introduced from information loss problem arising in black hole. In this paper we discuss the effect of scrambling from a perspective of pure quantum informa…

Tripartite entanglement and matrix inversion quantum algorithm

Mi-Ra Hwang, MuSeong Kim, Eylee Jung +2

The role of entanglement is discussed in the Harrow-Hassidim-Lloyd (HHL) algorithm. We compute all tripartite entanglement at every steps of the HHL algorithm. The tripartite entan…

Is entanglement a unique resource in quantum illumination?

MuSeong Kim, Mi-Ra Hwang, Eylee Jung +1

It is well-known that quantum illumination with a two-mode squeezed vacuum state as an initial entangled bipartite state achieves dB quantum advantage in the error probability…

Rényi and von Neumann entropies of thermal state in Generalized Uncertainty Principle-corrected harmonic oscillator

MuSeong Kim, Mi-Ra Hwang, Eylee Jung +1

The Rényi and von Neumann entropies of the thermal state in the generalized uncertainty principle (GUP)-corrected single harmonic oscillator system are explicitly computed within t…

Test of Common Sense in Quantum Copying Process

Mi-Ra Hwang, Eylee Jung, Kap Soo Jang +5

It is believed that the more we have {\it a priori} information on input states, the better we can make the quality of clones in quantum cloning machines. This common sense idea wa…

Effect of Phase Factor in the Geometric Entanglement Measure of Three-Qubit States

Sayatnova Tamaryan, Hungsoo Kim, Mu-Seong Kim +2

Any pure three-qubit state is uniquely characterized by one phase and four positive parameters. The geometric measure of entanglement as a function of state parameters can have dif…
