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…
