'Spectacular' progress has been made towards useful quantum computers

Fully practical quantum computers haven’t arrived yet, but the quantum computing industry is ending the year on an optimistic note. At the Q2B Silicon Valley conference in December, which brings together quantum business and science experts, the consensus seemed to be that the future of quantum computing is only getting brighter.

“On balance, we think it is more likely than not that someone, or maybe multiple someones, are going to be able to make a really industrially useful quantum computer, which is not something I thought I’d be concluding at the end of 2025,” said Joe Altepeter, programme manager for the US Defense Advanced Research Projects Agency’s Quantum Benchmarking Initiative (QBI) at a presentation during the conference. The goal of QBI is to determine which of the several currently competing approaches for building quantum computers can produce a useful device, which would also have to correct its own errors, or be fault-tolerant.
