We’re still a long way from realising the full potential of quantum computing, but scientists are making progress all the time – and as a sign of what might be coming, IBM now says it expects to have a 1,000 qubit machine up and running by 2023.
Qubits are the quantum equivalents of classical computing bits, able to be set not just as a 1 or a 0, but as a superposition state that can represent both 1 and 0 at the same time. This deceptively simple property has the potential to revolutionise the amount of computing power at our disposal.
With the IBM Quantum Condor planned for 2023 – running 1,121 qubits, to be exact – we should start to see quantum computers start to tackle a substantial number of genuine real-world calculations, rather than being restricted to laboratory experiments.
