New Canadian quantum computer called twice as powerful as last one, but what does that mean?
From CBC
There's a new quantum computer from Canadian company D-Wave on the market — one that is said to be twice as powerful as D-Wave's previous model.Read the rest of the full article here: http://www.cbc.ca/news/technology/dwave-new-quantum-computer-twice-as-fast-so-what-1.3949886The processor in D-Wave's new computer boasts 2,000 quantum bits, or qubits — the unit used to gauge a quantum computer's power — while its previous version only had 1,000. But what, exactly, does that mean?
In short: with more qubits, researchers can solve certain problems more efficiently, and in some cases, faster. Basically, it's an improvement on what D-Wave already sells.
But a universal quantum computer, one that can solve a wider range of problems, is still a way off.
"They have remained with the same architecture, but what they've done is they've increased its capacity for computation," explained Amr Helmy, a professor of electrical and computer engineering of the University of Toronto. he is also director of the university's Centre for Quantum Information and Quantum Control.
