A new wave of confidence — and capital — is sweeping through the quantum computing industry.
The governments of Australia and the state of Queensland this week committed A$940mn (US$620mn) between them to back the construction of a full-scale quantum computer near Brisbane by US start-up PSI Quantum. The deal was just the latest sign that a decades-old dream of a new form of computing that takes advantage of the unusual properties of quantum mechanics may finally be coming to fruition.
The system in Australia will be “the first machine that crosses over the threshold into [being a] really useful computer — the first quantum system in the world that will be commercially useful”, claimed Pete Shadbolt, PSI’s chief scientific officer.
