Hybrid Quantum Science

Research Interests

Twamley’s theory research focuses on investigating hybrid quantum systems where one considers connecting up a variety of different types of quantum sub-systems which, when taken together, can reveal new physics or perform new functions, beyond that of the individual sub-systems. An example of an hybrid system is a design that joins together photonic, superconducting and solid-state (diamond) sub-systems, to connect up via an optical fibre, distant superconducting quantum computers. Another example it to connect up electronic and vibrational sub-systems to design one-way directional quantum wires for electrons. The field of hybrid quantum engineering covers many sub-topics including, optomechanics, superconductors, solid-state quantum devices, optimal quantum control, quantum error correction, algorithms and simulation.
