Efficient contextual ontological model of $n$-qubit stabilizer quantum mechanics

Quantum Physics 2022-09-26 v2

Abstract

The most well-known tool for studying contextuality in quantum computation is the n-qubit stabilizer state tableau representation. We provide an extension that describes not only the quantum state, but is also outcome deterministic. The extension enables a value assignment to exponentially many Pauli observables, yet remains quadratic in both memory and computational complexity. Furthermore, we show that the mechanisms employed for contextuality and measurement disturbance are wholly separate. The model will be useful for investigating the role of contextuality in nn-qubit quantum computation.

Comments

Minor grammatical corrections. Added a table comparing our model to existing models. Expanded somewhat on the discussion in Conclusions. Added a link to a Python implementation of our model. 6 pages, 1 figure, 1 table
