Editing Quantum Bit Commitment (section)

==Protocol Description==
[https://github.com/quantumprotocolzoo/protocols/tree/master/QuantumBitCommitment <u>Click here for Python code</u>]</br>
The committer and the receiver agree on the space-time origin point P and two light-like separated points where the two agents of each party will be stationed.

===Commitment Phase===

''Receiver''
# Prepare a set of <math>N</math> qubits <math>|\psi_i\rangle_{i=1}^N</math> chosen independently and randomly from the BB84 states - <math>\{|0\rangle, |1\rangle, |+\rangle, |-\rangle\}</math>.
# Send the qubits to the commiter at point P.

''Commiter''
# To commit to 0, measure in the <math>\{|0\rangle, |1\rangle\}</math> basis.
# To commit to 1, measure in the <math>\{|+\rangle, |-\rangle\}</math> basis.
# Send the measurement outcomes to the agents <math>Q_0</math> and <math>Q_1</math> via the secure classical channels.

===Unveiling Phase===    

''Committer''
# The committer's agents reveal the measurement outcomes to the receiver's agents <math>Q'_0</math> and <math>Q'_1</math>.

''Receiver''
# Check if the revealed outcomes of both the agents are same, if not, then abort.
# Check if the revealed outcomes are consistent with the sent states, if not, then abort.
# If the checks pass, accept the commitment.
