PsiQuantum was founded in 2016 by four UK university physicists and has relocated to California where it has raised $215 million. The company's first quantum computer has been dubbed Q-1.
The company has revealed that it is using Globalfoundries wafer fabs in the US and Germany to make circuits.
"We’re now at a point where we have solved the critical roadblocks on the path to building a quantum computer with a million qubits, the scale required for all known useful commercial applications," Jeremy O’Brien, CEO of PsiQuantum, was quoted saying in a Financial Times article.
The quantum computing field is becoming crowded with as many as 200 startups eager to win a race and with multiple approaches to the quantum superpositioning that is at the heart of quantum computing efficiency.
Hermann Hauser, entrepreneur and co-founder of Amadeus Capital Partners, was quoted saying: "Jeremy and his brilliant team have their nose out in front because of their relationship with Globalfoundries and their level of funding."
It is also the case that PsiQuantum has turned to photonics, which is showing likely advantages over electron-based quantum computing.
