Google captivated the tech world Monday with Willow, a new quantum chip that outperformed even the world’s best supercomputer on an advanced test, and experts say this week’s revelations are just the start of a new phase in cutting-edge computing. The new chip, which wowed even Tesla CEO Elon Musk, can complete in five minutes a complex computation that would take the most powerful supercomputer 10 septillion years—more than the estimated age of the universe, wrote Hartmut Neven, the founder and leader of Google Quantum AI, in a blog post. Google researchers were also able to prove for the first time that the chip’s errors did not increase proportionately as the number of qubits, the basic information processing unit in a quantum computer, rises. The qubits in quantum computing are more prone to mistakes than a regular computer because they are highly sensitive to electromagnetic and other forms of interference and can only remain in a quantum state for very brief periods of time. But in order for a quantum chip’s calculations to make sense, it needs to have a very low error rate, Javad Shabani, a physics professor and director of the Center of Quantum Information Physics at New York University, told Fortune.
