Finite-Key Analysis of Quantum Key Distribution with Characterized Devices Using Entropy Accumulation
Ian George, Jie Lin, Thomas van Himbeeck +2
The Entropy Accumulation Theorem (EAT) was introduced to significantly improve the finite-size rates for device-independent quantum information processing tasks such as device-inde…

Improving device-independent weak coin flipping protocols
Atul Singh Arora, Jamie Sikora, Thomas Van Himbeeck
Weak coin flipping is the cryptographic task where Alice and Bob remotely flip a coin but want opposite outcomes. This work studies this task in the device-independent regime where…
