3 Coulomb Blockade Thermometry Verify and benchmark commercial electron thermometry (CBTs). Demonstrate record low electron temperatures in an on-chip, integrated device.

4 MF sensors and -wave detectors using graphene-superconductor hybrid structures Induced superconductivity in S-G-S structures Large electric-gate-tuneable supercurrent SQUIPT: superconducting quantum proximity effect transistor Magnetic field sensing for MEG Microwave single-photon sources/detectors for quantum information circuits

5 Fundamental electrical metrology: resistance and current standards Resistance standard using QHE in graphene Current standard based on single-electron pumps

6 Extreme quantum-enhanced primary thermometry Novel non-invasive thermometers for electron and phonon temperature measurement of quantum-enhanced devices. Essential enabling technology NEMS phonon thermometry Quantum dot thermometry

7 Quantum enhancement of THz technology for healthcare Development of portable THz sources and detectors Use them for coherent anti-stokes Raman spectroscopy (THz-CARS) Applications in situ diagnosis during surgery characterization of pharmaceuticals manufacturing, quality control, and process monitoring high-altitude telecommunications Working with clinicians of NHS Hospital in the North- West

8 Cryo-free ultra low temperature environment for quantum-enhanced sensors Develop a user-friendly, adjustable, portable instrument for QT sensors. Use colder dry dilution fridge technology to enable new materials and devices to be used.

9 Two more feasibility QT1.0 projects supported by IR single photon photodiodes Development of novel SPADs extending availability out across the IR spectrum Combining barrier device architectures with impact ionisation for high gain. GaSb/GaAs single photon sources GaSb/GaAs QRs hole localisation energy 600 mev Strong ensemble emission at telecoms wavelengths at RT and above Industry partners

10 QT for Information Security Quantum authentication ( atometrics ). Aim to provide keys for cryptography with the fewest resources (minimise SWaP requirements), with a system that is difficult to clone. Resonant tunnelling measurements through quantum dot diodes, and transport across 2D sheets are atomic-configuration dependent and robust. Ideal for fingerprinting applications. Post-quantum cryptography. A bioinspired algorithm is currently been tested, with implementations being developed by the industrial partners.

12 Nanofabrication facilities class 1000 and class 100 cleanrooms dedicated electron-beam writer plasma processing thin-film deposition

13 IsoLab ultra-isolated laboratory environment A visualisation of the site, and the support building surrounding (but isolated from) the pods, which houses the service equipment (pumps, instrumentation, etc) along with space for the operators running the experiments.

14 IsoLab design 1. Three concrete bunkers are sunk into the ground. 2. The inner surfaces of the bunkers are covered with electrical /anechoic shielding to minimise E- M fields and air-borne vibrations. 3. A 50 tonne concrete block is added to each volume to act as the vibrationally-isolated platforms. 4. The blocks are supported on air springs with access to experiment. 5. A modular experimental floor (in red) is added, part of which can be attached to the block for the experiment and part to the outer casing for access.
