Google’s 49 Qubit Chip
Google is maintaining its edge in the world of quantum computing. Its 20-qubit processor is currently undergoing tests, and the company appears to be on schedule to have its working 49-qubit chip ready by the end of 2017 as promised. Until it began trialing the 20-qubit chip, Google’s most powerful quantum chip was the 9-qubit effort from 2015.
Traditional computer bits are binary, only existing as either 0 or 1; they’re like light switches that are either on or off. Qubits, on the other hand, can be 0 or 1 like regular bits, but can also have quantum properties that allow them to exist in a superposition where they are both 0 and 1 simultaneously. This makes qubits potentially far more powerful, because instead of figuring something out by trying each option one by one, they can simultaneously compute more than one possibility.
