Bounds on Integrals of the Wigner Function
The integral of the Wigner function over a subregion of the phasespace of a quantum system may be less than zero or greater than one. It is shown that for systems with one degree of freedom, the problem of determining the best possible upper and lower bounds on such an integral, over all possible states, reduces to the problem of finding the greatest and least eigenvalues of an hermitian operat...
متن کاملQuantum Instability for Mixed States
The analysis of the time evolution of unstable states which are linear superposition of other, observable, states can, in principle, be carried out in two distinct, non-equivalent ways. One of the methods, usually employed for the neutral kaon system, combines the mixing and instability into one single step which then results into unconventional properties of the mass-eigenstates. An alternativ...
متن کاملQuantum computational logic with mixed states
Using an algebraic framework we solve a problem posed in [5] and [7] about the axiomatizability of a type quantum computational logic related to fuzzy logic. A Hilbert-style calculus is developed obtaining an algebraic strong completeness theorem.

متن کاملQuantum programming with mixed states ( extended abstract )
In this paper we offer a programming approach to quantum computation using mixed states. Mixed-state quantum systems generalise standard (pure) quantum systems by allowing the state of the system to be a probabilistic distribution of pure states. We build on previous work by Aharonov et al. and generalise their results from quantum circuits to probabilistic (and quantum) programs.
