===== Research Areas =====


  *     Foundations of quantum mechanics, quantum measurement, the quantum to classical transition and phase space methods.
  *     Open quantum systems - especially with regard to chaotic phenomena and control
  *     Quantum circuits, particularly those based on superconducting devices
  *     Quantum Computation and Quantum Information Processing
  *     Entanglement/separability in multi-partite and open quantum systems
  *     Realisations of condensed matter & photonic systems for quantum technologies
  *     Numerical analysis of stochastic and non-linear differential equations
  *     Quantum Computing


===== Group Research Areas =====

The QSE Research Group at Loughborough brings together a unique team of leading academic from diverse backgrounds - including quantum technologists, scientists, engineers and end users - in order to develop the methodology that will become Quantum Systems Engineering. Our interest in (Quantum [Systems) Engineering] spans the engineering of quantum-systems and the systems-engineering approach to quantum technologies.

===What we do===

Currently our group is actively researching the following areas:

  *     The application of Systems Engineering Methods to accelerate Blue-Sky and low technology readiness level devices and technologies.
  *     The development of new Systems Engineering methods that will be needed in the quantum technologies industry specifically in the areas of Quantum Design for Test, Reliability, Manufacture, etc. Here, for example, we are pioneering the use of phase space methods for feedback & control and certification of quantum systems.
  *     Additive manufacture for developing quantum technologies (currently our work is focused on superconductors).
  *     Quantum reliability engineering with an aim to develop a universal analysis of failure laboratory.
  *     Development of computer aided engineering solutions for the modeling and simulation of quantum technologies.
  *     Delivery of systems engineering training and mechanisms to enhance collaboration with the sector.
