Oplysninger om arrangementet
Advances in experimental condensed matter physics are often driven by the developments of new materials and new measurement probes. There is an emerging interest to develop and deploy qubit-like systems to perform “quantum sensing” measurements on complex quantum materials --- ultimately probing information such as many-body quantum correlation and entanglement, that may be commonly calculated theoretically but challenging to extract with conventional experimental techniques. I will describe our recent research efforts to develop hybrid quantum material structures as an enabling platform toward this goal, by combining “sensing materials” containing qubit-like entities or building blocks (ranging from superconducting Josephson junctions to optically addressed quantum emitters) with other interesting (topological or correlated) quantum materials to be studied. For example, I will discuss how nitrogen-vacancy (NV) centers in nano-diamonds and defect/color centers in 2D material boron nitrides (h-BN) may be used to measure magnetic/electric fields and their fluctuations and probe phase transitions in magnetic quantum materials.
