A Linear Programming Method for Finding Orthocomplements in Finite Lattices
George Parfionov, Roman Zapatrin
A method of embedding partially ordered sets into linear spaces is presented. The problem of finding all orthocomplementations in a finite lattice is reduced to a linear programmin…

How `hot' are mixed quantum states?
George Parfionov, Roman R. Zapatrin
Given a mixed quantum state of a qudit, we consider any observable as a kind of `thermometer' in the following sense. Given a source which emits pure states with these or t…

`Lazy' quantum ensembles
George Parfionov, Roman Zapatrin
We compare different strategies aimed to prepare an ensemble with a given density matrix . Preparing the ensemble of eigenstates of with appropriate probabilities can be tre…
