Setup requirements
For optimal operation, each qubit will require a DC source and AWG for flux biasing, RF AWG for driving and RF readout module for the readout. Readout is optimised in combination with a Crescendo-S TWPA for each of the four feedlines.
QuantWare’s Contralto-D QPU and Crescendo TWPA, with their high qubit coherence and effective circuit design in terms of qubit frequencies, coupling parameters, and connectivity, were essential in enabling us to accelerate both hardware and software development, significantly advancing our universal fault-tolerant quantum computing research.
