Six-State QKD: Three-Basis Eavesdropping Detection

Interactive quantum key distribution simulator: stream qubits from Alice to Bob, add a third measurement basis (six-state) or keep BB84's two, then switch on an intercept-resend eavesdropper and watch the QBER rise from a theoretical 25% to 33% in real time.

This simulation demonstrates the principles of quantum cryptography, specifically quantum key distribution (QKD), and how quantum mechanics can be used to create secure communication channels. A stream of qubits flies from Alice to Bob, each prepared in a randomly chosen basis and bit; toggle between BB84's two measurement bases and the six-state protocol's three, then switch on an intercept-resend eavesdropper to watch the sifted key rate and quantum bit error rate (QBER) shift in real time between the two protocols' theoretical values — 25% under BB84 versus 33% under six-state, the exact number that makes the third basis worth the lower sifting efficiency.
