We demonstrate a modular solid state architecture with deterministic inter-module coupling between four physically separate, interchangeable superconducting qubit integrated circuits.
Learn MoreWe introduce an approximate description of an N--qubit state, which contains sufficient information to estimate the expectation value of any observable with precision.

Read MoreWe highlight a certain member of the "XY-family" for which many two-qubit programs admit expression as low-depth circuits.
Read 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 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.
