PhD position in Quantum Computing theory at Queen Mary University of London, UK Application deadline: Wednesday, January 28, 2026Employer web page: https://www.qmul.ac.uk/spcs/phdresearch/application-process/#applyJob type: PhDPostDocTags: quantum computingquantum algorithmquantum informationquantum complexity theoryAvailable to home and outstanding international applicants. Quantum technologies are advancing rapidly, raising a central question for the field: Can quantum computers solve physically relevant problems better than classical computers? Understanding this requires overcoming theoretical challenges at the intersection of quantum information, many-body physics, and complexity theory. This PhD project aims to explore the capabilities and limitations of quantum computation and develop quantum algorithms for tackling quantum problems. You will work on a range of closely connected topics, which, for example, may include: Complexity of quantum dynamics, and its quantum simulation. Study the fundamental computational complexity involved in simulating the time evolution of many-body quantum systems. This includes exploring links with quantum thermalisation, open quantum system dynamics, and the emergence of classical behaviour. We will develop new quantum algorithms for simulating quantum processes more efficiently. Quantum algorithms We will investigate the potential for quantum computers in quantum problems. This includes finding eigenstates of many-body Hamiltonians, simulating quantum dynamics, Hamiltonian learning, quantum thermalisation, and characterising phases of matter. Insights may have implications for quantum error correction, non-Markovian behaviour, quantum memory effects, and noise-resilient quantum computation. New notions of quantum computation We will also explore quantum sensing and spectroscopy from a quantum-computational perspective. This will link concepts from quantum information with physical notions such as correlations functions, response theory and fingerprints of many-body systems. We may think about new notions of quantum computing that is beyond current ‘qubit’ and ‘qumode’ frameworks.
