Superconducting cavity probes sliding ferroelectricity in small-angle twisted WSe
Krishnendu Maji, Supriya Mandal, Sriram H. +8
Ferroelectricity is a property of materials that exhibit spontaneous charge polarization. Ferroelectricity in 2D materials is interesting because of their applications in memory de…
Kerr non-linearity enhances the response of a graphene Josephson bolometer
Joydip Sarkar, Krishnendu Maji, Abhishek Sunamudi +8
Highly sensitive, broadband bolometers are of great interest because of their versatile usage in wide areas starting from dark matter search, radio astronomy, material science, and…
The quantromon: A qubit-resonator system with orthogonal qubit and readout modes
Kishor V. Salunkhe, Suman Kundu, Srijita Das +3
The measurement of a superconducting qubit is implemented by coupling it to a resonator. The common choice is transverse coupling, which, in the dispersive approximation, introduce…
High-fidelity QND readout and measurement back-action in a Tantalum-based high-coherence fluxonium qubit
Gaurav Bothara, Srijita Das, Kishor V Salunkhe +4
Implementing a precise measurement of the quantum state of a qubit is very critical for building a practical quantum processor as it plays an important role in state initialization…
