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 ...

Explaining the Unobserved: Why Quantum Mechanics Is Not only About Information [PDF]

open access: yes, 2005
A remarkable theorem by Clifton, Bub and Halverson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be ...

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.

The Bicomplex Quantum Harmonic Oscillator

open access: yesIl Nuovo Cimento B, 2010
The problem of the quantum harmonic oscillator is investigated in the framework of bicomplex numbers, which are pairs of complex numbers making up a commutative ring with zero divisors. Starting with the commutator of the bicomplex position and momentum operators, and adapting the algebraic treatment of the standard quantum harmonic oscillator, we find

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 ...

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.

Exact diagonalization of the D-dimensional spatially confined quantum harmonic oscillator [PDF]

open access: yesKragujevac Journal of Science, 2016
In the existing literature various numerical techniques have been developed to quantize the confined harmonic oscillator in higher dimensions. In obtaining the energy eigenvalues, such methods often involve indirect approaches such as searching for the ...
