Randomness can be certified in energy-constrained semi-device-independent scenarios
Shashank Kumar Ranu, Lewis Wooltorton, Alastair A. Abbott +1
The prepare-and-measure framework based on energy constraints offers a practical middle ground between fully device-dependent and device-independent quantum cryptography. The only…
Chain rules for conditional entropies in quantum cryptography: limitations and improvements
Lewis Wooltorton, Peter Brown, Omar Fawzi
Security proofs in quantum cryptography rely on conditional entropies. In a many-round protocol, their estimation is a challenging task; one must account for the most general attac…
Quantum Nonlocality and Device-Independent Randomness are Robust to Noisy Signaling Channels
Kuntal Sengupta, Lewis Wooltorton
Given a pair of isolated devices that accept random binary inputs and return binary outputs, a user can deduce from the observed data alone if the underlying mechanism can be expla…
Numerical security framework for quantum key distribution with bypass channels
Lewis Wooltorton, Twesh Upadhyaya, Mohsen Razavi
Satellite based quantum key distribution (QKD) aims to establish secure key exchange over long distances despite significant technological challenges. To alleviate some of these ch…
