Summary on Grant Application Form
Quantum technology initiative is focused on bringing quantum sensors and quantum devices to market and end users. Quantum Sensors offer unquestioned performance advantages in sensitivity and some steps have been made at making more compact systems. But for genuine and widespread applications substantial improvements need to be made in size, weight and power ('SWAP') and ruggedness of these systems. A stable laser is the bedrock for quantum quantum sensors for timing, gravity and magnetic field. They are also the key to secure communication, quantum computation and quantum imaging. In addition to SWAP, such systems need to encompass the wavelength ranges, which are not so easily accessible today. In this project, we aim to develop a laser platform matching the optical performance of current commercial lasers (e.g. Ti:S laser from M2 and Coherent) in a footprint but with a price point comparable to the external-cavity diode laser (ECDL). We plan to demonstrate that such a platform can operate on many otherwise difficult-to-access but crucial lines. Such a development will be a critical step on the road to the translation of QT from the research community to the defence, space and consumer market. In the short term, economic opportunity will arise from the supply chain building activities, delivering novel world leading underpinning technologies. The aimed laser platform will leap frog us in the exploitation of global QT research. The research groups world wide often dream of having turn-key systems. In the medium term, the UK will become the supplier of choice for early low-volume, high-value applications of QT (finance, space) and in the long- term we will be ideally placed to exploit the inevitable transition of QT to the consumer market. The work done in the project will also have a tangle impact on the space sector. In brief, this project will bring reduction in volume, power, size and cost by over an order of magnitude and this will done without losing their performance and robustness. These components are enormously critical, thereby leap frogging the UK QT development and commercialisation.
