Google recently announced a major breakthrough in quantum computing when its Willow processor solved an equation that would take a conventional computer practically forever. But PsiQuantum, the company planning to build in Chicago one of the world’s first commercially viable quantum computers, is taking a different path. Instead of building a small-scale quantum computer designed primarily for testing and public demonstrations, PsiQuantum is shooting for the moon with a 1 million-quantum-bit machine capable of tackling practical, real-world applications. It’s a future that even leading scientists aren’t sure is possible.
