Superdense coding: how to send two bits using one qubit | Quantum computing for the determined

Name: Superdense coding: how to send two bits using one qubit | Quantum computing for the determined
Uploaded: 2010-11-24
Description: Two classical bits using one transmitted qubit sounds like a loophole. Michael Nielsen introduces superdense coding and the resources behind the headline. Watch this as part of the communication sequence, with pre-shared entanglement included in the accounting rather than treating the transmitted qubit as the entire protocol.
