Abstract:We present a novel scheme of Cyclic remote implementation of partially unknown quantum operations (CRIPUQO) via a six‐qubit entangled state as the quantum channel. Alice can remotely apply a partially unknown quantum operation Ud (d = 0,1) to Bob's qubit b, and Bob can remotely apply Ud to Charlie's site; meanwhile, Charlie can also remotely apply Ud to Alice's qubit c. It is pointed out that the CRIPUQO in the opposite direction can be perfectly achieved by changing the quantum channel. The scheme above is al… Show more
