Realization of two-qutrit quantum algorithms on a programmable superconducting processor

Tanay Roy, Ziqian Li, Eliot Kapit +1

Processing quantum information using quantum three-level systems or qutrits as the fundamental unit is an alternative to contemporary qubit-based architectures with the potential t…

Error-divisible two-qubit gates

David Rodriguez Perez, Paul Varosy, Ziqian Li +3

We introduce a simple, widely applicable formalism for designing "error-divisible" two qubit gates: a quantum gate set where fractional rotations have proportionally reduced error…

Tomography in the presence of stray inter-qubit coupling

Tanay Roy, Ziqian Li, Eliot Kapit +1

Tomography is an indispensable part of quantum computation as it enables diagnosis of a quantum process through state reconstruction. Existing tomographic protocols are based on de…

Universal fast flux control of a coherent, low-frequency qubit

Helin Zhang, Srivatsan Chakram, Tanay Roy +6

The \textit{heavy-fluxonium} circuit is a promising building block for superconducting quantum processors due to its long relaxation and dephasing time at the half-flux frustration…

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…
