I’m thrilled to congratulate PsiQuantum—the company focused on delivering the world’s first fault tolerant quantum computer with one million physical qubits—on their successful Series D round.
We first invested in PsiQuantum during their Series C fundraise announced in April 2020 and our conviction is steadfast: PsiQuantum has a plausible vision and execution plan to achieve a universal, fault tolerant quantum computer on a realistic time horizon and within sensible cost projections. The advent of a useful number of logical qubits in a fault tolerant quantum processor holds the potential to accelerate important discoveries in materials science and chemistry, opening the door to commercial breakthroughs like much more efficient batteries, improved fertilizers for agriculture, or catalysts for carbon sequestration.
From the outset, PsiQuantum has remained heads-down and focused on their long-term mission to build a commercially viable quantum computer, and the team remains committed to achieving their goal via a disciplined engineering execution plan. They are not reliant on achieving new fundamental scientific breakthroughs to realize this ambition. However, tackling several hard engineering problems is par for the course when the agenda is as ambitious as changing the paradigm of computing! Challenges include designing and implementing quantum system engineering methodologies at an unprecedented level of scale and precision; and advancing the state of the art in performance of silicon photonics manufacturing processes, packaging, and assembly—all while continuing to refine a quantum computer architecture that is ideally suited for photonic qubits.
