Superconducting Through-Silicon Vias for Quantum Integrated Circuits
Mehrnoosh Vahidpour, William O'Brien, Jon Tyler Whyland +12
We describe a microfabrication process for superconducting through-silicon vias appropriate for use in superconducting qubit quantum processors. With a sloped-wall via geometry, we…
Superconducting Caps for Quantum Integrated Circuits
William O'Brien, Mehrnoosh Vahidpour, Jon Tyler Whyland +12
We report on the fabrication and metrology of superconducting caps for qubit circuits. As part of a 3D quantum integrated circuit architecture, a cap chip forms the upper half of a…
Demonstration of Universal Parametric Entangling Gates on a Multi-Qubit Lattice
M. Reagor, C. B. Osborn, N. Tezak +56
We show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors. By inducing coherent population exchange between a…
Parametrically Activated Entangling Gates Using Transmon Qubits
S. Caldwell, N. Didier, C. A. Ryan +59
We describe and implement a family of entangling gates activated by radio-frequency flux modulation applied to a tunable transmon that is statically coupled to a neighboring transm…
