We’re thrilled to report some exciting results from our superconducting dual resonator qubit systems.

First, we achieved a State Preparation and Measurement (SPAM) error of 0.003%.  This equates to a SPAM quality of 99.997%.

Second, we measured single qubit gate fidelities of 0.084% using the same system.

With a system in which erasure errors are the dominant sources of loss, wherein bit and phase flip error rates are exceedingly low, we plan to continue down the path toward scalable and fault-tolerant quantum error correction.
