Technology

FrostByte designs cryogenic electronics in standard commercial semiconductor processes rather than custom or lab-scale fabrication. Building on mature, high-volume process technology reduces manufacturing variability relative to bespoke approaches, gives us a direct route to volume production on existing foundry capacity as channel counts grow, and keeps component costs at a level that supports system deployment rather than one-off experiments. We characterise and qualify each design for cryogenic operation ourselves, on top of a process base that is already proven at scale.

Our team's design record spans the full signal chain for quantum device control: RF and microwave generation, precision biasing, multiplexed readout, and the digital logic that ties them together, integrated on single mixed-signal dies and verified at cryogenic temperatures. This work covers multiple qubit platforms and is documented in peer-reviewed publications in leading journals.
