Efficient Classical Simulation of the DQC1 Circuit with Zero Discord [PDF]

open access: yesQuantum
A path for efficient classical simulation of the DQC1 circuit that estimates the trace of an implementable unitary under the zero discord condition \cite{dakic2010necessary} is presented.

Quantum discord dynamical behaviors due to initial system-cavity correlations

open access: yes, 2010
We analyze the roles of initial correlations between the two-qubit system and a dissipative cavity on quantum discord dynamics of two qubits. Considering two initial system-cavity states, we show that the initial system-cavity correlations not only can ...

Super-quantum discord in ferromagnetic and antiferromagnetic materials [PDF]

open access: yesQuantum Information Processing, 2019
Super-quantum discord is an extension of the quantum discord concept where weak measurements are made instead of projective measurements. We study the temperature behavior of the super-quantum discord for two real magnetic materials.

Quantum discord and Fisher information for two-qubit system in the presence of thermal fields

open access: yesAIP Advances, 2023
We consider a double Jaynes–Cummings model for a system of two atoms that interact with a radiation field defined in a thermal spin state. We examine the impact of the parameters of the quantum model on the temporal evolution of quantum discord, quantum ...

Super quantum discord for X-type states

open access: yes, 2014
Weak measurement is a new way to manipulate and control quantum systems. Different from projection measurement, weak measurement only makes a small change in status.

Branching States as The Emergent Structure of a Quantum Universe [PDF]

open access: yesQuantum
Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insights about the emergence of classical phenomenology, centered around quantum
