Engineering Cross Resonance Interaction in Multi-modal Quantum Circuits
Sumeru Hazra, Kishor V. Salunkhe, Anirban Bhattacharjee +5
Existing scalable superconducting quantum processors have only nearest-neighbor coupling. This leads to reduced circuit depth, requiring large series of gates to perform an arbitra…
Multiplexed readout of four qubits in 3D cQED architecture using broadband JPA
Suman Kundu, Nicolas Gheeraert, Sumeru Hazra +4
We propose and demonstrate a frequency-multiplexed readout scheme in 3D cQED architecture. We use four transmon qubits coupled to individual rectangular cavities which are aperture…
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…
Understanding the saturation power of Josephson Parametric Amplifiers made from SQUIDs arrays
Luca Planat, Remy Dassonneville, Javier Puertas Martinez +7
We report on the implementation and detailed modelling of a Josephson Parametric Amplifier (JPA) made from an array of eighty Superconducting QUantum Interference Devices (SQUIDs),…
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…
Implementation of pairwise longitudinal coupling in a three-qubit superconducting circuit
Tanay Roy, Suman Kundu, Madhavi Chand +7
We present the "trimon", a multi-mode superconducting circuit implementing three qubits with all-to-all longitudinal coupling. This always-on interaction enables simple implementat…
