(a) Schematics of hybrid teleportation from an unknown superconducting state in A to a CV cavity field in C. The states of A and M are superconducting qubits in orange lines while that of B and C are cavity fields in red lines. The transmon qubit M is used for preparation of a ECS and decoupled enough cavity C from B. The part of implementing the BSM scheme has been demonstrated very recently in80. (b) Circuit diagram for creating and verifying an ECS61.
is a conditional displacement with 2α while D−α does unconditional one with −α.
makes a π-flip operation of the qubit M at a vacuum state in modes B and C. DB and DC indicate detectors for cavity states. The final detection schemes are explained in the section of the verification scheme for ECSs.
