On the generation of discrete unitary gates from continuous time forced Schrodinger equations
Claudio Altafini
Abstract
In all the various proposals for quantum computers, a common feature is that the quantum circuits are expected to be made of cascades of unitary transformations acting on the quantum states. A framework is proposed to express these elementary quantum gates directly in terms of the control inputs entering into the continuous time forced Schrodinger equation.
