Summary
QDV makes standardised auxiliary electronic equipment that allows quantum computing (QC) R&D to control qubits at millikelvin (mK) temperatures in a dilution refrigerator (DR) and reduces noise and interference in the experiment.
QDV electronics produce and send low-frequency signals through 48 channels, filters noise from signal channels, and holds the qubit sample inside the DR at 10mK. QDV technology lets researchers focus on qubit characterisation, and far less time and funding resources on constructing complex and expensive arrays of control electronics needed for qubit experimentation.
The main bottleneck in QC is the technology used to characterise qubits. It is not upscaling with the number of qubits that can be integrated into a processor – up to 70. A single qubit may need up to 20 signal channels. Current options offer no more than 8 channels. The extra channels add unwanted thermal and electronic noise to the experimental system which undoes qubit superpositional states.
QDV and its QCAUX electronics address this bottleneck directly. QDV will use Accelerator funding to improve the functionality of our QCAUX beta electronics, and add the features and functionalities indicated by the beta end users and the findings of the Phase I Feasibility Study.
The outcomes will be a digital-analogue converter with up to 240 signal channels which transmit at up to 4.2GHz, an automated breakout box, an RF/RC filter with 100 channels, a new filter for superconductor qubit R&D, and a modular sample holder with mother and daughterboards that transmit signals up to 42GHz.
End users can improve and upscale their R&D by using a standardised chain of electronic devices with up to 240 signal channels, and deploy staff time in quantum research and away from configuring in-house electronics. QCAUX will cost €68k, equivalent to what QC R&D teams spend per year on in-house electronics for a single DR.
