Title:     Quantum sensing with superconducting devices

Abstract: Superconducting devices are currently one of the main candidates for the implementation of quantum computers. These devices have features that make them interesting for quantum sensing as well. I will discuss two topics in quantum sensing based on superconducting systems. 

The first topic is the use of superconducting flux qubits as magnetometers. Detection of magnetic fields using a Ramsey protocol, similarly to atomic magnetometry, leverages the large effective magnetic moment of flux qubits, and leads to very high detection efficiency potentially exceeding that of other magnetometers.  

The second topic is quantum sensing based on superconducting levitodynamics. Levitated superconductors were shown recently to achieve very low loss rates at milliKelvin temperatures. Coupling levitated superconducting spheres to superconducting qubits and resonators enables new protocols for motion detection, which can be leveraged to develop versatile sensors for various applications. 

In the final part of my talk, I will discuss prospects for using superconducting quantum sensors for fundamental physics.
