Can quantum-mechanical description of physical reality be considered incomplete?

Gilles Brassard, Andre Allan Methot

In loving memory of Asher Peres, we discuss a most important and influential paper written in 1935 by his thesis supervisor and mentor Nathan Rosen, together with Albert Einstein a…

A father protocol for quantum broadcast channels

Frédéric Dupuis, Patrick Hayden, Ke Li

A new protocol for quantum broadcast channels based on the fully quantum Slepian-Wolf protocol is presented. The protocol yields an achievable rate region for entanglement-assisted…

Local Distinguishability of Any Three Quantum States

Somshubhro Bandyopadhyay, Jonathan Walgate

We prove that any three linearly independent pure quantum states can always be locally distinguished with nonzero probability regardless of their dimension, entanglement, or multip…

Simulation of bipartite qudit correlations

Julien Degorre, Sophie Laplante, Jérémie Roland

We present a protocol to simulate the quantum correlations of an arbitrary bipartite state, when the parties perform a measurement according to two traceless binary observables. We…

POVMs and Naimark's theorem without sums

Bob Coecke, Eric Oliver Paquette

We provide a definition of POVM in terms of abstract tensor structure only. It is justified in two distinct manners. i. At this abstract level we are still able to prove Naimark's…

Manipulating time-bin qubits with fiber optics components

Felix Bussieres, Yasaman Soudagar, Guido Berlin +2

We propose two experimental schemes to implement arbitrary unitary single qubit operations on single photons encoded in time-bin qubits. Both schemes require fiber optics component…

Decoy state quantum key distribution with two-way classical post-processing

Xiongfeng Ma, Chi-Hang Fred Fung, Frédéric Dupuis +3

Decoy states have recently been proposed as a useful method for substantially improving the performance of quantum key distribution protocols when a coherent state source is used.…

Brief History of Quantum Cryptography: A Personal Perspective

Gilles Brassard

Quantum cryptography is the only approach to privacy ever proposed that allows two parties (who do not share a long secret key ahead of time) to communicate with provably perfect s…

Inseparability of Quantum Parameters

Indranil Chakrabarty, S. Adhikari, Prashant +1

In this work, we show that 'splitting of quantum information' [6] is an impossible task from three different but consistent principles of unitarity of Quantum Mechanics, no-signall…
