Utility-scale quantum computers require quantum error correcting codes with large numbers of physical qubits to achieve sufficiently low logical error rates. The performance of quantum error correction (QEC) is generally predicted through large-scale numerical simulations, used to estimate thresholds, finite-size scaling, and exponential suppression of logical errors below threshold. The...

Quantum resources such as magic, quasi-probabilistic negativity and entanglement are necessary for quantum advantage. However, the presence of noise provides a mechanism for the potential decay of quantum resources and the onset of efficient classical simulability. Classical simulations of noisy quantum circuits are instrumental to our understanding of the behavior of real-world quantum...

Our work forms two connected parts. The part-1 studies a class of computational problems associated with stabilizer states. The part-2 focuses on developing new state-of-the-art classical simulation algorithms.

Part-1: Stabilizer states are ubiquitous in quantum computing because they exhibit many important quantum properties such as superposition, entanglement and contextuality whilst...
