Usually, the quantum optical phase-space displacement operator D(α)=exp(αâdagger−α*â) is used to describe the displacements in Alice's measurement basis and Bob's correction operation for continuous-variable quantum teleportation. Here, we prefer to stick to the WH group elements, where Z(v)X(u) differs from D(α) only by a global phase with α=u+iv. Alice's measurement basis is then described by [Z(v)X(u) big dot times 1]integral dx∣x›∣x›√π. Bob's correction operation would be Z(v)X(u) in this case. In a communication rather than computation scenario where Alice and Bob are spatially separated, of course, Alice needs to send the results u and v to Bob via a classical channel.
