Deterministic bidirectional quantum-controlled teleportation with six-qubit maximally entangled state

Abstract

A theoretical scheme for bidirectional swapping quantum controlled teleportation is presented using the entanglement property of maximally entangled five-qubit state, i.e., Alice wants to transmit a entangled state of particle a to Bob and Bob wants to transmit a entangled state of particle bto Alice via the control of the supervisor Charlie.

Off-axis digital holography based on the Sagnac interferometer

“…When an aerosol and paramecium are measured by this device, the results are not affected by humidity and temperature. Now, some researchers want to combine quantum technology [23,24] with DH [25,26] to improve the resolution of holography and detect single photons [27]. This expands the application of off-axis DH.…”

Cyclic deterministic bidirectional quantum controlled teleportation with maximally seven-qubit entangled state

“…Any one of the three parties can be the controller, and BQCT can be realized between the other two parties. To date, a number of articles have studied the BQCT scheme based on the principle of entanglement swapping [28][29][30][31][32][33][34][35]. However, none have achieved the role transition between controller and receiver in such a complex seven-qubit entangled state.…”
