We demonstrate a modular solid state architecture with deterministic inter-module coupling between four physically separate, interchangeable superconducting qubit integrated circuits.
Learn MoreFor superconducting qubits, uncontrolled variation of nominal performance makes obtaining such resolution challenging. We approach this problem by investigating specific combinations of previously reported fabrication techniques on the quality of 242 thin film superconducting resonators and qubits.
Read MoreWe experimentally validate the existence of this AC sweet spot and demonstrate its dependence on white noise power from room temperature electronics.
Read MoreWe 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 transmon.
Read MoreWe find that simple filtering of the flux control signal allows for entangling gates to operate in a novel sweet-spot for dephasing under flux modulation.
Read MoreWe show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors.
Read MoreWe describe a microfabrication process for superconducting through-silicon vias appropriate for use in superconducting qubit quantum processors.
Read MoreWe report on the fabrication and metrology of superconducting caps for qubit circuits.
Read MoreWe propose a flux-tunable superconducting qubit that minimizes the dephasing due to magnetic flux noise by engineering controllable flux “sweet spots” at frequencies of interest.
Read MoreWe focus on superconducting quantum processors based on transmons for which full numerical simulations are already challenging at the level of qubytes.
Read MoreWe describe such a functional architecture, based on a planar lattice of transmon and fluxonium qubits, parametric amplifiers, and a novel fast DC controlled two-qubit gate.
Read MoreWe introduce an abstract machine architecture for classical/quantum computations.
