The generalised semi-Clifford conjecture is false
Nadish de Silva, Oscar Lautsch
The Clifford hierarchy is a nested sequence of sets of quantum gates that can be fault-tolerantly performed using gate teleportation within standard quantum error correction scheme…
Three-qubit nonlocality paradoxes: beyond GHZ
Nadish de Silva, Santanil Jana, Ming Yin
Quantum nonlocality paradoxes, such as that of GHZ, provide maximally sharp logical obstructions to classical probabilistic models of quantum correlations. They are key resources i…
Bases for optimising stabiliser decompositions of quantum states
Nadish de Silva, Ming Yin, Sergii Strelchuk
Stabiliser states play a central role in the theory of quantum computation. For example, they are used to encode computational basis states in the most common quantum error correct…
Fast algorithms for classical specifications of stabiliser states and Clifford gates
Nadish de Silva, Wilfred Salmon, Ming Yin
The stabiliser formalism plays a central role in quantum computing, error correction, and fault tolerance. Conversions between and verifications of different specifications of stab…
Characterising semi-Clifford gates using algebraic sets
Imin Chen, Nadish de Silva
Motivated by their central role in fault-tolerant quantum computation, we study the sets of gates of the third-level of the Clifford hierarchy and their distinguished subsets of `n…
