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…

Composable framework for device-independent state certification
Rutvij Bhavsar, Lewis Wooltorton, Joonwoo Bae
Certifying a quantum state in a device-independent (DI) manner, in which no trust is placed on the internal workings of any physical components, is a fundamental task bearing vario…

Genuine multipartite entanglement is not necessary for standard device-independent conference key agreement
Lewis Wooltorton, Peter Brown, Roger Colbeck
Conference key agreement aims to establish shared, private randomness among many separated parties in a network. Device-independent conference key agreement (DICKA) is a variant in…
