Universal Hamiltonian control in a planar trimon circuit
Vivek Maurya, Daria Kowsari, Kumar Saurav +4
Multimode circuits provide an avenue for flexible control of single and multi-qubit gates. In this work we implement a multimode circuit known as a trimon integrated in a planar ge…

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…
