Quantum algorithms and computation is a research area focused on exploiting quantum mechanical principles—such as superposition, entanglement, and interference—to design computational models and algorithms with capabilities beyond classical computing. It encompasses the study of quantum complexity classes, algorithmic paradigms (e.g., phase estimation, amplitude amplification, variational and adiabatic methods), and architectures for quantum circuits and measurement-based computation. The field investigates provable speedups for problems like factoring, simulation of quantum systems, optimization, and sampling, along with resource requirements, error models, and fault-tolerant schemes, thereby linking theoretical computer science, quantum information theory, and physical realizations of quantum processors.
Manchester's quantum researchers are building on the Ferranti Mark I legacy, using ultra-pure silicon and single atoms to move quantum computing closer to real-world impact.
