Quantum Control Design by Lyapunov Trajectory Tracking and Optimal Control

open access: yesEntropy
In this paper, we investigate a Lyapunov trajectory tracking design method that incorporates a Schrödinger equation with a dipole subterm and polarizability.

Equivalent circuit and numerical analyses of an inductively coupled plasma torch with a tapped induction coil

open access: yesAIP Advances, 2018
Equivalent circuit and numerical analyses of an Ar-N2 inductively coupled plasma (ICP) were conducted in order to clarify the effect of the induction coil with a grounded tap on the electrical characteristics of an ICP torch system.

A topological nonlinear parametric amplifier

open access: yesNature Communications, 2022
Here the authors report the development of a topological nonlinear parametric amplification in a dimerized, Su-Schrieffer-Heeger waveguide. Kerr-induced chiral symmetry breaking is demonstrated, showcasing how nonlinearities may control transitions of ...

Quantum Knots and Mosaics

open access: yes, 2008
In this paper, we give a precise and workable definition of a quantum knot system, the states of which are called quantum knots. This definition can be viewed as a blueprint for the construction of an actual physical quantum system.

Detection of biological signals from a live mammalian muscle using an early stage diamond quantum sensor

open access: yesScientific Reports, 2021
The ability to perform noninvasive and non-contact measurements of electric signals produced by action potentials is essential in biomedicine. A key method to do this is to remotely sense signals by the magnetic field they induce.

Process tomography via sequential measurements on a single quantum system [PDF]

open access: yes, 2015
We utilize a discrete (sequential) measurement protocol to investigate quantum process tomography of a single two-level quantum system, with an unknown initial state, undergoing Rabi oscillations. The ignorance of the dynamical parameters is encoded into

Neutronic analysis of effects of inboard materials on the size of a tokamak fusion reactor

open access: yesNuclear Materials and Energy, 2021
The effects of inboard materials on the size of a tokamak fusion reactor were studied based on reactor system parameters determined through a coupled analysis of tokamak systems and neutron transport. With an inboard blanket, the shielding capability was

The solution of the quantum $A_1$ T-system for arbitrary boundary

open access: yes, 2011
We solve the quantum version of the $A_1$ $T$-system by use of quantum networks. The system is interpreted as a particular set of mutations of a suitable (infinite-rank) quantum cluster algebra, and Laurent positivity follows from our solution.

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Quantum simulation of thermodynamics in an integrated quantum photonic processor

open access: yesNature Communications, 2023
One of the core questions of quantum physics is how to reconcile the unitary evolution of quantum states, which is information-preserving and time-reversible, with evolution following the second law of thermodynamics, which, in general, is neither.
