Microsoft says it's made a major breakthrough in quantum computing capabilities with Majorana 1, its first quantum chip, and the first of its kind to be powered by what are called topological qubits. Here's what that means for quantum computing.

Amazon has unveiled its first quantum computing chip today, after four years in the making. Dubbed Ocelot, it uses 'cat qubits' for improved error correction, and could lead to cheaper practical quantum computing in the years to come.

In a proposal that reads more like the script to a new sci-fi movie, researchers are suggesting a unique way to tackle one of the core problems of quantum computing. If deployed, it would redefine how we think of "cloud computing."

Practical quantum computers may be another step closer to reality, thanks again to graphene. The bits of information in quantum computers (qubits) can exist in two states at once, and now researchers have managed to record just how long that superposition state can last in a qubit made of graphene.
