A Generalized Quantum Slepian-Wolf
In this work we consider a quantum generalization of the task considered by Slepian andWolf [1] regarding distributed source compression. In our task Alice, Bob, Charlie and Reference share a joint pure state. Alice and Bob wish to send a part of their respective systems to Charlie without collaborating with each other. We give achievability bounds for this task in the one-shot setting and prov...
متن کاملA generalized quantum microcanonical ensemble
We discuss a generalized quantum microcanonical ensemble. It describes isolated systems that are not necessarily in an eigenstate of the Hamilton operator. Statistical averages are obtained by a combination of a time average and a maximum entropy argument to resolve the lack of knowledge about initial conditions. As a result, statistical averages of linear observables coincide with values obtai...

متن کاملGeneralized Quantum Measurement
We overcome one of Bell’s objections to ‘quantum measurement’ by generalizing the definition to include systems outside the laboratory. According to this definition a generalized quantum measurement takes place when the value of a classical variable is influenced significantly by an earlier state of a quantum system. A generalized quantum measurement can then take place in equilibrium systems, ...
متن کاملGeneralized quantum potentials
We first recall that the system of fluid mechanics equations (Euler and continuity) that describes a fluid in irrotational motion subjected to a generalized quantum potential (depending on a constant which may be different from the standard quantum constant h̄) is equivalent to a generalized Schrödinger equation for a ‘wavefunction’ whose modulus squared yields the fluid density. Then we show th...
