Our take
As quantum computing shifts from the realm of theory to that of reality, Quandela is here to facilitate its accelerated uptake. The company supplies access to Quantum Processing Units via the "Quandela Cloud", and is also developing photonic quantum computers to sell to industrial customers.
Through its cloud gateway, users can submit jobs to Quandela's quantum computers and monitor them from an online interface, helping to make quantum computing more widely accessible. The company also runs a computing platform called MosaiQ, through which new quantum computing algorithms and protocols can be prototyped, developed, and implemented.
Having already made strides in the sector, Quandela's latest focus is the delivery of its commercial quantum computers, the first of which was bought and hosted by cloud provider OVHcloud in an industry-first transaction. Funding will support the expansion of this side of the business and otherwise support the company's as-yet-confidential roadmap.
