TY - JOUR ID - 806322 AU - Ziman, Mário - Rybár, Tomáš PY - 2008 TI - Repeatable quantum memory channels JF - Phys. Rev. A VL - 78 IS - 5 SP - 052114 EP - 052114 SN - 10502947 KW - Repeatable quantum memory channels UR - http://arxiv.org/abs/0808.3851 N2 - Within the framework of quantum memory channels we introduce the notion of repeatability of quantum channels. In particular, a quantum channel is called repeatable if there exist a memory device implementing the same channel on each individual input. We show that random unitary channels can be implemented in a repeatable fashion, whereas the nonunital channels cannot. ER -
