High-threshold magic state distillation with quantum quadratic residue codes
Michael Zurel, Santanil Jana, Nadish de Silva
We present applications of quantum quadratic residue codes in magic state distillation. This includes showing that existing codes which are known to distill magic states, like the…

A Classification Program for Nonlocality Paradoxes of Three Qubits
Nadish de Silva, Santanil Jana, Ming Yin
Nonlocality is a quintessential signature of nonclassical behaviour and a resource for quantum advantages in communication and computation. The paradoxical correlations witnessed b…

Matchgate hierarchy: A Clifford-like hierarchy for deterministic gate teleportation in matchgate circuits
Angelos Bampounis, Rui Soares Barbosa, Nadish de Silva
The Clifford hierarchy, introduced by Gottesman and Chuang in 1999, is an increasing sequence of sets of quantum gates crucial to the gate teleportation model for fault-tolerant qu…
