BECOME A LEADER IN QUANTUM BY SCALING BEYOND WITH VIO

Contralto-A is a first step on your roadmap. It is engineered to enable cost-efficient upgrading to larger QPUs powered by VIO, QuantWare’s proprietary scaling platform.

system requirements

Contralto-A is delivered fully packaged and is compatible with Ardent connectors. Magnetic shielding is available as an option.

For optimal operation, each qubit requires a RF AWG for driving and RF readout module for the readout. Each qubit and each tunable coupler require a DC source and AWG for flux biasing. Readout is optimised in combination with a Crescendo-S TWPA for each of the three feedlines.
