Results in brief
Quantum Information in Quantum Imaging
The principles of quantum mechanics are being used to achieve a new paradigm in metrology, the science of measurement. This *quantum metrology* increases precision which in turn (i) reveals foundational insight in quantum information theory and (ii) promises the next evolution in sensors. Single parameter estimation (e.g. interferometry) is widely investigated and the optimal resources and classes of measurements are identified. This maturity now allows application of the rigour of quantum metrology to other fields, such as quantum imaging — including imaging without detection techniques — and quantum process tomography. The challenge is to extend the quantum metrology framework to multiple parameter estimation, requiring theoretical and experimental effort to explore and identify the optimal resources and classes of measurements. I propose a novel scheme for full quantum process tomography, using multi-parameter quantum metrology combined with the imaging without detection technique. This unites previously disparate fields to achieve a new paradigm of quantum measurement physics and precision sensing technology. I will adapt and modify ghost-imaging schemes for simultaneous object estimation, investigate the role of nonclassical correlations to deepen understanding of quantum measurements and its information extracting capabilities. This project accelerates standard quantum metrology that until now has focused on single parameters and single objects. The use of free-space quantum optics for proof-of principle experiments and integrated silicon quantum photonics will allow us to reach higher levels of complexity and capability.
