The receiver securely pre-prepares a set of qubits randomly from the BB84 states and sends them to the commiter.
The receiver securely pre-prepares a set of qubits randomly chosen from the BB84 states and sends them to the commiter.
To commit to the bit 0, the commiter measures the received qubits in the standard basis and in Hadamard basis to commit to 1.
To commit to the bit 0, the commiter measures the received qubits in the standard basis and in Hadamard basis to commit to 1.
The commiter then sends the outcomes to their agents over secure classical channels.

The receiver's agents then check if the outcomes they have received are the same and consistent with the states sent to the commiter.
The receiver's agents then check if the outcomes they have received are the same and consistent with the states sent to the commiter.
If the check passes, the receiver accepts the commitment.
