CONDITIONAL CONTROLLED PHASE SHIFT OPERATION FOR QUANTUM STATES OF ELECTROMAGNETIC FIELD
Read the full article
Abstract
A model of three qubit quantum logical gate of conditional double controlled phase shift is suggested. Quantum unit of information – qubit – is encoded by polarization state of quantum mode of optical cavity. A conditional operator which acts on a field states is obtained. It is shown that this operator works as required phase transformation under the certain conditions with high possibility.
