Logical Reversibility and Physical Reversibility in Quantum Measurement
A quantum measurement is logically reversible if the premeasurement density operator of the measured system can be calculated from the postmeasurement density operator and from the outcome of the measurement. This paper analyzes why many quantum measurements are logically irreversible, shows how to make them logically reversible, and discusses reversing measurement that returns the postmeasurem...
متن کاملReversibility in Extended Measurement-Based Quantum Computation
When applied on some particular quantum entangled states, measurements are universal for quantum computing. In particular, despite the fondamental probabilistic evolution of quantum measurements, any unitary evolution can be simulated by a measurement-based quantum computer (MBQC). We consider the extended version of the MBQC where each measurement can occur not only in the (X,Y)-plane of the B...
متن کاملImportance of reversibility in the quantum formalism.
In this Letter I stress the role of causal reversibility (time symmetry), together with causality and locality, in the justification of the quantum formalism. First, in the algebraic quantum formalism, I show that the assumption of reversibility implies that the observables of a quantum theory form an abstract real C^{⋆} algebra, and can be represented as an algebra of operators on a real Hilbe...
متن کاملThe Reversibility of Interacting Fleming-Viot Processes
Fleming-Viot process is a mathematical model in population genetics. It is a probabilitymeasure-valued process describing the relative frequencies of allelic types in a large population undergoing mutation, selection and genetic drift. The interacting Fleming-Viot process describes the evolution of a collection of Fleming-Viot processes in which those Fleming-Viot processes interact with each o...
متن کاملA Reversibility Problem for Fleming-viot Processes
Fleming-Viot processes incorporating mutation and selection are considered. It is well-known that if the mutation factor is of uniform type, the process has a reversible stationary distribution, and it has been an open problem to characterize the class of the processes that have reversible stationary distributions. This paper proves that if a Fleming-Viot process has a reversible stationary dis...
