Light-Matter Interaction in dispersive Superconducting Circuit QED
Harsh Arora, Jay Deshmukh, Ansh Das +2
It is well known that superconducting waveguides strongly attenuate the propagation of electromagnetic waves with frequencies beyond the superconducting gap. In circuit QED, the in…

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…
