Key Rate Analysis of a 3-State Twin-Field Quantum Key Distribution Protocol in the Finite-key Regime. (arXiv:2305.18006v2 [quant-ph] UPDATED)

When analysing Quantum Key Distribution (QKD) protocols several metrics can
be determined, but one of the most important is the Secret Key Rate. The Secret
Key Rate is the number of bits per transmission that result in being part of a
Secret Key between two parties. There are equations that give the Secret Key
Rate, for example, for the BB84 protocol, equation 52 from [1, p.1032] gives
the Secret Key Rate for a given Quantum Bit Error Rate (QBER). However, …
