Nature: D-Wave upgrade: How scientists are using the world’s most controversial quantum computer
"The company that makes the world’s only commercially available quantum computers has released its biggest machine yet — and researchers are paying close attention. Named 2000Q after the number of quantum bits, or qubits, within its processor, the machine, made by D-Wave of Burnaby, Canada, has almost twice as many qubits as its predecessor. Many researchers remain sceptical about the long-term potential of such machines, whose approach differs from that of other nascent quantum computers. But others are already booking time on D-Wave’s computers to explore challenges from machine learning to cybersecurity.
Moreover, improvements to 2000Q, the company’s fourth-generation machine, are largely a result of researchers’ feedback." Read the article at Nature.
