No-faster-than-light-signaling implies linear evolutions. A re-derivation

Angelo Bassi, Kasra Hejazi

There is a growing interest, both from the theoretical as well as experimental side, to test the validity of the quantum superposition principle, and of theories which explicitly v…

A Proof for Poisson Bracket in Non-commutative Algebra of Quantum Mechanics

Sina Khorasani

The widely accepted approach to the foundation of quantum mechanics is that the Poisson bracket, governing the non-commutative algebra of operators, is taken as a postulate with no…

Entanglement from dissipative dynamics into overlapping environments

Riccardo Mengoni, Laleh Memarzadeh, Stefano Mancini

We consider two ensembles of qubit dissipating into two overlapping environments, that is with a certain number of qubit in common that dissipate into both environments. We then st…

Monotone Measures for Non-Local Correlations

Salman Beigi, Amin Gohari

Non-locality is the phenomenon of observing strong correlations among the outcomes of local measurements of a multipartite physical system. No-signaling boxes are the abstract obje…

Quantum Metrology: Extended Convexity of Quantum Fisher Information

S. Alipour, A. T. Rezakhani

We prove an extended convexity for quantum Fisher information of a mixed state with a given convex decomposition. This convexity introduces a bound which has two parts: i. classica…

Scheme for measurement-based quantum computation on projected entangled-pair states

Mear M. R. Koochakie

Recently it has been shown that projected entangled-pair states can be considered as a (physically motivated) resource state for measurement-based quantum computation. Here we elab…
