Min-entropy uncertainty relation for finite-size cryptography
Min-entropy uncertainty relation for finite-size cryptography
Apart from their foundational significance, entropic uncertainty relations play a central role in proving the security of quantum cryptographic protocols. Of particular interest are therefore relations in terms of the smooth min-entropy for Bennett-Brassard 1984 (BB84) and six-state encodings. The smooth min-entropy ${H}_{\mathrm{min}}^{\ensuremath{\epsilon}}(X/B)$ quantifies the negative logarithm of the probability …
