Dynamic Distance Measure on Spaces of Isospectral Mixed Quantum States
Distance measures are used to quantify the extent to which information is preserved or altered by quantum processes, and thus are indispensable tools in quantum information and quantum computing. In this paper we propose a new distance measure for mixed quantum states, which we call the dynamic distance measure, and we show that it is a proper distance measure. The dynamic distance measure is d...
متن کاملOn Isospectral Arithmetical Spaces
We study the relationship between the arithmetic and the spectrum of the Laplacian for manifolds arising from congruent arithmetic subgroups of SL(1, D), where D is an indefinite quaternion division algebra defined over a number field F . We give new examples of isospectral but non-isometric compact, arithmetically defined varieties, generalizing the class of examples constructed by Vigneras. T...
متن کاملGeometric Measure of Quantum Entanglement for Multipartite Mixed States
The geometric measure of quantum entanglement of a pure state, defined by its distance to the set of pure separable states, is extended to multipartite mixed states. We characterize the nearest disentangled mixed state to a given mixed state with respect to the geometric measure by means of a system of equations. The entanglement eigenvalue for a mixed state is introduced. And we show that, for...
متن کاملFinite Quantum Measure Spaces
Measure and integration theory is a well established field of mathematics that is over a hundred years old. The theory possesses many deep and elegant theorems and has important applications in functional analysis, probability theory and theoretical physics. Measure theory can be applied whenever you are measuring something whether it be length, volume, probabilities, mass, energy, etc. Althoug...
متن کاملIsospectral Metrics on Weighted Projective Spaces
We construct the first examples of families of bad Riemannian orbifolds which are isospectral with respect to the Laplacian but not isometric. In our case these are particular fixed weighted projective spaces equipped with isospectral metrics obtained by a generalization of Schüth’s version of the torus method.
