Stochastic Qubits [PDF]

open access: yes, 2015
A new concept of qubits is given by considering entanglement of ordinary quibits with quantum measuring devices (micro-detectors). They are called stochastic qubits since they are generalized coherent states used in the stochastic (phase space) quantum ...

Quantum Error Correction with Mixed Ancilla Qubits

open access: yes, 2012
Most quantum error correcting codes are predicated on the assumption that there exists a reservoir of qubits in the state $\ket{0}$, which can be used as ancilla qubits to prepare multi-qubit logical states. In this report, we examine the consequences of

Flying qubit carrying a spin qubit [PDF]

open access: yesNature Photonics, 2013
Complete quantum control of an electron spin qubit can be achieved using a long-lived quantum-dot spin qubit coupled to a GaAs-based photonic-crystal cavity. Samuel Carter from the Naval Research Laboratory says that this system could be used as a node in a quantum network.

New Entropic Inequalities and Hidden Correlations in Quantum Suprematism Picture of Qudit States

open access: yesEntropy, 2018
We study an analog of Bayes’ formula and the nonnegativity property of mutual information for systems with one random variable. For single-qudit states, we present new entropic inequalities in the form of the subadditivity and condition ...

Quantum Computing: A Concise Introduction

open access: yesEncyclopedia
Quantum computing is an emerging field in computing technology that harnesses the principles of quantum mechanics—including superposition, entanglement, and quantum tunneling—to process information in fundamentally new ways. While classical computers use

Influence of dipole-dipole interaction and detuning on the entanglement of two qubits induced by a thermal field

open access: yesФизика волновых процессов и радиотехнические системы, 2017
In this paper we have investigated the dynamics of entanglement of two identical qubits nonresonantly interacting with one mode of a thermal electromagnetic field in lossless resonator in the presence of a direct dipole-dipole interaction.

Beyond Bits: A Review of Quantum Embedding Techniques for Efficient Information Processing

open access: yesIEEE Access
The existing body of research on quantum embedding techniques is not only confined in scope but also lacks a comprehensive understanding of the intricacies of the quantum embedding process.

Theory of solid state quantum information processing

open access: yes, 2004
Recent theoretical work on solid-state proposals for the implementation of quantum computation and quantum information processing is reviewed. The differences and similarities between microscopic and macroscopic qubits are highlighted and exemplified by ...
