Hamiltonian of a flux qubit-LC oscillator circuit in the deep–strong-coupling regime

open access: yesScientific Reports, 2022
We derive the Hamiltonian of a superconducting circuit that comprises a single-Josephson-junction flux qubit inductively coupled to an LC oscillator, and we compare the derived circuit Hamiltonian with the quantum Rabi Hamiltonian, which describes a two ...

Lissajous curves and semiclassical theory: The two-dimensional harmonic oscillator [PDF]

open access: yes, 2006
The semiclassical treatment of the two-dimensional harmonic oscillator provides an instructive example of the relation between classical motion and the quantum mechanical energy spectrum.

Quantum harmonic oscillator with time-dependent mass [PDF]

open access: yesModern physics letters B, 2017
We use the Fourier operator to transform a time-dependent mass quantum harmonic oscillator into a frequency-dependent one. Then we use Lewis–Ermakov invariants to solve the Schrödinger equation by using squeeze operators. Finally, we give two examples of

Information-Theoretic Models for Physical Observables

open access: yesEntropy, 2023
This work addresses J.A. Wheeler’s critical idea that all things physical are information-theoretic in origin. In this paper, we introduce a novel mathematical framework based on information geometry, using the Fisher information metric as a particular ...

Finite quantum kinematics of the harmonic oscillator [PDF]

open access: yesJournal of Mathematical Physics, 2006
Arbitrarily small changes in the commutation relations suffice to transform the usual singular quantum theories into regular quantum theories. This process is an extension of canonical quantization that we call general quantization. Here we apply general quantization to the time-independent linear harmonic oscillator.

Quadratic open quantum harmonic oscillator [PDF]

open access: yesLetters in Mathematical Physics, 2020
We study the quantum open system evolution described by a Gorini-Kossakowski-Sudarshan-Lindblad generator with creation and annihilation operators arising in Fock representations of the $sl_2$ Lie algebra. We show that any initial density matrix evolves to a fully supported density matrix and converges towards a unique equilibrium state.

Density Profiles, Energy, and Oscillation Strength of a Quantum Dot in Two Dimensions with a Harmonic Oscillator External Potential using an Orbital-free Energy Functional Based on Thomas–Fermi Theory

open access: yesMakara Journal of Science, 2016
This research aims i) to determine the density profile and calculate the ground state energy of a quantum dot in two dimensions (2D) with a harmonic oscillator potential using orbital-free density functional theory, and ii) to understand the effect of ...

High-fidelity quantum information transmission using a room-temperature nonrefrigerated lossy microwave waveguide

open access: yesScientific Reports, 2022
Quantum microwave transmission is key to realizing modular superconducting quantum computers and distributed quantum networks. A large number of incoherent photons are thermally generated within the microwave frequency spectrum.
