Abstracts: 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.
Key words: optical quantum computation, universal quantum computer, optical CNOT gate, quantum memory, quantum shutter, interaction-free measurement, quantum interrogation
