Abstract:

The idea of the design is proposed for the photonic quantum gates PG with their inputoutput properties based on nonlinear optical dynamics of 2D arrays of two-level systems TLS in the resonance field of coherent optical pulses. As a particular example of the 2D medium with functions of the PG we consider the GaAsAlGaAs-based 2D excitonic structures. By methods of femtosecond chronopolarimetry of delayed photoreflection. we have studied the energy and phase relaxation rates and the biexciton binding energy in these structures and have shown that the GaAsAlGaAs MQW can serve as a good basis for building the PG.
