Probing tunable Kerr nonlinearity in graphene Josephson junctions
Priyanka Samanta, Joydip Sarkar, Ashish Abhraham Samuel +4
Josephson junction (JJ) is a key nonlinear element in superconducting devices such as qubits, amplifiers, and bolometers. Recently, gate-tunable JJs based on graphene and semicondu…
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…
Long-range connectivity in a superconducting quantum processor using a ring resonator
Sumeru Hazra, Anirban Bhattacharjee, Madhavi Chand +4
Qubit coherence and gate fidelity are typically considered the two most important metrics for characterizing a quantum processor. An equally important metric is inter-qubit connect…
A programmable three-qubit superconducting processor with all-to-all connectivity
Tanay Roy, Sumeru Hazra, Suman Kundu +3
Superconducting circuits are at the forefront of quantum computing technology because of the unparalleled combination of good coherence, fast gates and flexibility in design parame…
Quantum Trajectory Distribution for Weak Measurement of a Superconducting Qubit: Experiment meets Theory
Parveen Kumar, Suman Kundu, Madhavi Chand +2
Quantum measurements are described as instantaneous projections in textbooks. They can be stretched out in time using weak measurements, whereby one can observe the evolution of a…
Multi-mode superconducting circuits for realizing strongly coupled multi-qubit processor units
Tanay Roy, Madhavi Chand, Anirban Bhattacharjee +4
Inter-qubit coupling and qubit connectivity in a processor are crucial for achieving high fidelity multi-qubit gates and efficient implementation of quantum algorithms. Typical sup…
