This skill introduces quantum-inspired methods, that is algorithms and heuristics that execute on conventional computing systems, while drawing on concepts, mathematical structures or problem formulations originating in quantum computing and quantum physics.
Learners develop a structured overview of major families of quantum-inspired approaches, including tensor-network techniques exploiting limited entanglement or low-rank structure, dequantised classical counterparts of selected quantum linear-algebra and sampling primitives, and optimisation heuristics based on Quadratic Unconstrained Binary Optimisation (QUBO) formulations, which encode optimisation problems as energy-minimisation tasks, or their equivalent Ising-model representations, motivated by annealing-style approaches. Emphasis is placed on understanding why such methods can be effective on classical hardware, the structural assumptions they rely upon, and how to evaluate them rigorously against strong classical baselines in realistic High-Performance Computing environments.
The focus is on conceptual understanding, structural analysis and critical performance evaluation rather than detailed mathematical derivation or low-level optimisation.
