“…However, it is difficult to create a big number of indistinguishable photons. In [2], an alternative simulator of the quantum logic using nonlinear optics has been proposed.

“…Following [2], two different realizations of the multi-component vector solitons are considered. These are the solitons propagated in the multi-component Bose-Einstein condensate (self-focusing (SF) described with multi-component nonlinear Schrödinger (NLS) equation) and in media displaying the self-induced transparency (SIT) of a V-bouquet configuration of [6].…”

In a concept of simulating the quantum logic with vector solitons by the author (Janutka 2006 J. Phys. A: Math. Gen. 39 12505), the soliton polarization is thought of as a state vector of a system of cebits (classical counterparts of qubits) switched via collisions with other solitons. The advantage of this method of information processing compared to schemes using linear optics is the possibility of the determination of the information-register state in a single measurement. Minimization of the information-processing error for different optical realizations of the logical systems is studied in the framework of a quantum analysis of soliton fluctuations. The problem is considered with relevance to general difficulties of the quantum error-correction schemes for the classical analogies of the quantum-information processing.
