Abstract
A technique relates to communication of a quantum state. Polarization hardware is configured to receive a polarization encoded qubit and split the polarization encoded qubit into two qubits. A converter is coupled to the polarization hardware, and the converter is configured to convert the two qubits into a form suitable for a CNOT gate. The CNOT gate is configured to receive the two qubits such that a measurement result of a CNOT operation of the CNOT gate determines success of the communication of the quantum state.
