An efficient construction of Raz's two-source randomness extractor with improved parameters
Cameron Foreman, Lewis Wooltorton, Kevin Milner +1
Randomness extractors are algorithms that distill weak random sources into near-perfect random numbers. Two-source extractors enable this distillation process by combining two inde…

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…
