| Abstract: | The paper investigates an odd particle composite quantum state combined with W-state and Bell-state. It is shown that this composite quantum state can be used to prefect teleportation of arbitrary single and two qubit, and also can be commendably utilized for superdense coding and quantum state sharing. The paper presents the measurement basis of sender and unity operations of receiver for teleportation protocol. It is found that five classical bits can be sent by conveying only three quantum bits for superdense coding. |
