Universal Quantum Computation with Shutter Logic

Quantum Physics 2007-05-23 v3

Abstract

We show that universal quantum logic can be achieved using only linear optics and a quantum shutter device. With these elements, we design a quantum memory for any number of qubits and a CNOT gate which are the basis of a universal quantum computer. An interaction-free model for a quantum shutter is given.
