That's still a long way from the 90 percent or more required for a practical quantum circuit, but it's a big step in the right direction. (sciencedaily.com)
Google had it simulate the behaviour of quantum circuits on increasingly larger grids of qubits, up to a 6 × 7 grid of 42 qubits. (newscientist.com)
The study demonstrates that complex quantum circuits can be built relatively easily out of silicon and silica — a significant milestone on the road to full - blown quantum computing. (newscientist.com)
