Can differently prepared mixed states be distinguished ?
A measurement has been proposed by B. d'Espagnat that would distinguish ensembles described by the same density matrix. This proposal is made precise and shown why it does not work in cases analogous to the EPR experiment .
متن کاملWhat Can Be Computed Locally?
1 Summary The paper [1] deals with locality on several levels: It introduces a model for distributed computations and the notion of locally checkable labelings (LCLs). It proves properties about algorithms for locally checkable labeling problems. Two algorithms are analyzed in detail: One for the Weak Coloring problem and one for the Formal Dining Philosophers problem. The paper shows fundament...
متن کاملWhat Can Be Verified Locally?
We are considering distributed network computing, in which computing entities are connected by a network modeled as a connected graph. These entities are located at the nodes of the graph, and they exchange information by message-passing along its edges. In this context, we are adopting the classical framework for local distributed decision, in which nodes must collectively decide whether their...
متن کاملWhat Can be Sampled Locally?
The local computation of Linial [FOCS’87] and Naor and Stockmeyer [STOC’93] concerns with the question of whether a locally definable distributed computing problem can be solved locally: more specifically, for a given local CSP whether a CSP solution can be constructed by a distributed algorithm using local information. In this paper, we consider the problem of sampling a uniform CSP solution b...
