We develop a new method of representation of quantum states in terms of thedisplaced number states. We call it representation, where is an amplitude ofthe base displaced states. In particular, representation was obtained for setof the displaced number states with different amplitude of the displacement,two-mode squeezed vacuum (TMSV) and superposition of vacuum and single photon.The treatment is employed for building of elementary linear operators, inparticular, two-qubit control-sign gate, Hadamard matrix between twotwo-dimensional Hilbert spaces. Main idea underlying the method is extractionof the displaced number state from initial state. Coherent qubit with largeamplitude taken simultaneously two modes shifts two-mode target qubit on phaseplane and constructive interference appears after measurement of single photon.The results are exact, any approximations are not exploited. We showimplementation of the gates with almost unity fidelity of the output states ispossible in realistic scenario.
