Resumen del contexto y de los objetivos generales del proyecto

Quantum computers (QCs) use the quantum states of subatomic particles embedded in the architecture of a processor to perform complex mathematical operations that classical computers cannot do. QCs use qubits as their basic unit of information. The challenge for QC is getting enough qubits into superposition and sustaining them there for long enough to perform meaningful computations. Qubits are very sensitive to any external interference. Qubits must be physically connected to the outside world by signal channels to electronic instruments that measure their behaviour. Signal channels cause interference which disrupts qubit quantum states and stops any computational processes.
The beneficiary of this Phase I proposal (‘QDV’) manufactures auxiliary electronics (‘QCAux’) which link quantum processors to the external operator. QDV has a beta version of QCAux used by QC R&D enterprises and institutions, with positive results and with important constructive feedback as to how QCAux can be improved. End users want standardised equipment with greater practical functionality that allows users to upscale their R&D by testing more qubits in each experiment, but without the extra signal channels that cause signal interference.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

The Feasibility Study investigated the QC R&D auxiliary electronics market: its size, growth trends 2018-2025, the type of end users, competitor enterprises and their technology, and how their technology compares to QCAux. The Feasibility Study examined the modifications that QDV can make to QCAux to better align it with end user feedback: how to add experimental capacity to QCAux without adding noise to the experiment. This was turned into tasks which would be the basis of future QCAux technology maturation. The Feasibility Study also looked at how QCAux can be commercialised, the third parties needed to reach market, and the economic returns for QDV.

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

The Feasibility Study confirmed that QDV and QCAux enjoy a major technical advantage over competitors. We operate in a market that will grow at >30% per year from now to 2025. We can add practical value and experimental capacity to QCAux with incremental design changes to each device in the QCAux system, which will have the sum effect of increasing the test capacity and practical value of QCAux in a QC R&D setting.
