Counterexamples to additivity of minimum output -Rényi entropy of quantum channels for and
Debbie Leung, Benjamin Lovitz, Peixue Wu
The authors construct explicit finite‑dimensional quantum channels that violate additivity of the minimum output p‑Rényi entropy for all Rényi orders p > 3/4 and 0 ≤ p < 1/4, narro…
On Error Thresholds for Pauli Channels: Some answers with many more questions
Avantika Agarwal, Alan Bu, Amolak Ratan Kalra +3
This paper focuses on error thresholds for Pauli channels. We numerically compute lower bounds for the thresholds using the analytic framework of coset weight enumerators pioneered…
Conditional disclosure of secrets with quantum resources
Vahid R. Asadi, Kohdai Kuroiwa, Debbie Leung +3
The conditional disclosure of secrets (CDS) primitive is among the simplest cryptographic settings in which to study the relationship between communication, randomness, and securit…
Quantum Reverse Shannon Theorem Revisited
Zahra Baghali Khanian, Debbie Leung
Reverse Shannon theorems concern the use of noiseless channels to simulate noisy ones. This is dual to the usual noisy channel coding problem, where a noisy (classical or quantum)…
