Quantum Cryptography – Equations & Interpretations

🔁 BB84 Basis Encoding#

• Z-basis: |0⟩, |1⟩
• X-basis: |+⟩ = (|0⟩ + |1⟩)/√2, |−⟩ = (|0⟩ − |1⟩)/√2

🧠 Triadic Interpretation#

• Object: Qubit
• Attribute: Basis choice
• Condition: Channel fidelity

🔐 Key Agreement Probability#

[ P_{\text{match}} = \frac{1}{2} ]

• Probability that sender and receiver chose same basis

🎭 Mythic Echo#

“The qubit does not hide—it waits to be asked correctly.”
— Nawder Loswin
