Path Integral for Quantum Operations
Vasily E. Tarasov
In this paper we consider a phase space path integral for general time-dependent quantum operations, not necessarily unitary. We obtain the path integral for a completely positive…

Quantum Computer with Mixed States and Four-Valued Logic
Vasily E. Tarasov
In this paper we discuss a model of quantum computer in which a state is an operator of density matrix and gates are general quantum operations, not necessarily unitary. A mixed st…
