   Keynote: Quantum Technologies for Long-term Data Security

   Presenter: Gregoire Ribordy, ID Quantique

    Presentation Details  Add to Schedule

   Quantum computing poses a major threat to the most commonly deployed public key cryptography algorithms, which are key building blocks of our information security infrastructure. With advances in the field of quantum computing, it becomes important to upgrade this infrastructure to use approaches with a resistant to this threat. One approach is to use quantum technologies, such as quantum key distribution and quantum random number generation, in combination with traditional cryptographic techniques in order to enhance their resilience. In this presentation, we will review the current state of the art of practical quantum key distribution and quantum random number generators and discuss current areas of research. We will also present examples of applications and use cases.

   Sensing with Diamond NV Centers: the Double-edged Sword of Sensitivity

   Presenter: Ania Bleszynski Jayich, University of California Santa Barbara

    Presentation Details  Add to Schedule

   
   Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale imaging of condensed matter and biological systems with sensitivity to single nuclear spins. Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems, where we have imaged current flow patterns in graphene as well as skyrmions, nanoscale spin textures. A grand challenge to improving the spatial resolution and magnetic sensitivity of the NV is mitigating surface-induced quantum decoherence, which I will discuss in the second part of this talk. Decoherence at interfaces is a universal problem that affects many quantum technologies, but the microscopic origins are as yet unclear. Our studies guide the ongoing development of quantum control and materials control, pushing towards the ultimate goal of NV-based single nuclear spin imaging.
