This advance could help in scaling up quantum computers for practical use. Although small-scale quantum computers have been demonstrated, the challenge of scaling up these computers to millions of qubits remains. This is because, for the qubits to exist in a state of quantum superposition, they need to be isolated; and at the same time they need to interact and communicate with other qubits.

14:44 Phys.orgComplexity test offers new perspective on small quantum computers

State-of-the-art quantum devices are not yet large enough to be called full-scale computers. The biggest comprise just a few dozen qubits—a meager count compared to the billions of bits in an ordinary computer's memory. But steady progress means that these machines now routinely string together 10 or 20 qubits and may soon hold sway over 100 or more.
