Malaney works on quantum communications with an emphasis on the satellite channel: continuous- and discrete-variable QKD through atmospheric turbulence, entanglement distribution from space, and the use of Gaussian and squeezed states as the carriers. A distinct thread is quantum-enhanced sensing and localisation — quantum illumination and quantum radar — where entangled probe states are used to detect weakly-reflecting targets in noisy backgrounds. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his work belongs to the nonclassical-light arm of the search: it addresses whether squeezing and entanglement can be preserved through a lossy channel well enough to deliver a real metrological advantage, which is the practical question that determines whether quantum-enhanced sensing can ever beat a well-engineered shot-noise-limited pT/sqrt(Hz) device. Largely theory/simulation with some experimental collaboration.
