Quantum computing startup PsiQuantum has landed a $450 million series-D investment putting them at a $3.15 billion valuation. They plan to build its machine using photons, or particles of light, as qubits. One of the advantages of this method is that it could help the machine perform reliable calculations without errors. One of the challenges that they will need to overcome is that it will need to introduce new, higher-performance components into its existing manufacturing process. One example of such a component is a more efficient waveguide, which is used to route photons inside the chip. To this end, they struck a deal with GlobalFoundries, announced in May, to build its quantum chips at GlobalFoundries’ manufacturing facilities.

PsiQuantum’s semiconductor engineering talent was one of the main motivations for investing in the startup, Mr. Kumar said. “They have advanced to the state of being an engineering-driven company. This is not a science project,” Mr. Kumar said.
