Quantum memory can operate not only as a write-in/readout device  for quantum light pulses and non-classical states generation  device but also as a quantum states of light transformer. Here the addressable parallel quantum memory  possibilities for this type of transformation are researched. Quantum memory operates as a conventional N-port interferometer with N equals to the number of the involved spin waves. As example we consider the ability to transform quantum states of two light pulses – in this case the quantum memory works as a mirror with a controlled transmission factor.
Key words: quantum optics / quantum information / quantum memory / squeezed and entangled states / spin waves
