Magnetic and Bolometric Sensor Embedded in a Josephson Parametric Amplifier
Abstract
Quantum sensors have the potential to bring about a revolution in sensing across disciplines of physical sciences. Particularly, single-photon detectors and magnetic sensors are at the heart of various quantum information processing in astronomy and material science. Recently, 2D van der Waals (vdW) materials have emerged as an attractive platform for bolometric applications because of their unique thermodynamic properties. To date, the widely used sensitive bolometers are transition edge sensors (TESs) and kinetic inductance detectors (KIDs) which provide a noise equivalent power (NEP) ~ 500 zW- √Hz. 2D vdW material-based bolometers have provided further improvement in NEP and response time by exploiting the material properties, however, the NEP can be further improved by improving the intrinsic noise level of the detector. Here we propose a magnetic and bolometric sensor using a graphene-based Josephson parametric amplifier (JPA). Because of the extreme sensitivity of the JPA non-linearity and quantum noise-limited operation, such bolometers have the potential to sense at individual magnon and photon levels with minimal backaction. This is contrary to other platforms, where to date quantum-limited noise performance in bolometers has not been demonstrated yet.
