Abstract

© 2016 IOP Publishing Ltd.We have considered theoretically the feasibility of broadband quantum memory based on the resonant tripod-type atomic configuration. In this case, the writing of a signal field is carried out simultaneously into two channels, and characterized by an excitation of two spin waves of the atomic ensemble. With simultaneous read out from both channels, quantum properties of the original signal are mapped onto the retrieval pulse no worse than in the case of memory based on a Λ-type atomic configuration. At the same time new possibilities are opened up for the manipulation of quantum states associated with sequential reading out (and/or sequential writing) of signal pulses. For example, a pulse in the squeezed state is converted into two partially entangled pulses with partially squeezed quadratures. Alternatively, two independent signal pulses with orthogonally squeezed quadratures can be converted into two entangled pulses.
