Google’s 49-qubit chip will allow them to develop a 49-qubit quantum system that can solve problems that are far beyond the capacity of ordinary computers: Google calls this goal quantum supremacy. The 20-qubit system that the Google quantum computing team is now working on currently boasts a “two-qubit fidelity” of 99.5 percent. The higher the rating, the fewer errors the system makes. Quantum supremacy demands not only a 49-qubit system, but also sufficient accuracy to achieve a two-qubit fidelity of at least 99.7 percent—which Google is on track to deliver by the end of 2017.

QUANTUM COMPUTING, QUANTUM SPEED

Google isn’t alone in their quest for advancing quantum computing. In 2016, IBM was running a 5 qubit computer, but by May 2017, it was offering beta access to its 16 qubit platform to the public for testing purposes. Furthermore, qubits alone aren’t the only consideration for actually achieving working quantum computers; error correction and scaling will also be critical to quantum systems. However, if Google does achieve quantum supremacy, it will be a major step forward.
