Our take
Quantum computing will change the world more than any other imminent technological development, and PsiQuantum sits at the forefront of the charge to build the first quantum computer that will actually work.
The company is unique for the scale of their ambitions. Rather than focusing on what they term “intermediate milestones” like building smaller proof of concept systems, PsiQuantum builds the first large-scale, error-corrected computer, using photonics to deliver over 1,000,000 qubits (current quantum machines have yet to cross the 1,000 qubit mark).
There are plenty of companies building quantum computers, including the likes of IBM and Google, but these prototypical machines lack the size to correct errors, making them exponentially less useful than what PsiQuantum aims for. While other companies operate in the same sphere, PsiQuantum is unequivocally a leader in its field, founded by world-class academics and recently securing $1B in funding, making it the largest funding round for a quantum computing startup.
