A big step up: Two qubit computing
Step by step we’re moving closer to useful quantum computing. A big step, announced by the National Institute of Standards and Technology (NIST, USA), was the demonstration of a computing device using two qubits. Previous demonstrations by various researchers have used one qubit. In computing, two computational units are far more powerful than one. This [...]
Quantum computing and image recognition
One of the many things that’s easy for (adult) humans and very difficult for computers is image recognition. Take twenty thousand pictures of a street, half with cars and half without. A human being will separate car pictures from non-car pictures with about 100% accuracy (if not falling asleep from boredom). Not so for computers, [...]
