Google solved a complex problem in minutes with a quantum computer that would take today’s most powerful supercomputer thousands of years to crack
BERLIN — Google said on Wednesday it had achieved a breakthrough in computer research, by solving a complex problem in minutes with a so-called quantum computer that would take today’s most powerful supercomputer thousands of years to crack.
So, whereas traditional computing relies on bits, or ones and zeros, quantum computing uses quantum bits, or qubits, that can be both one and zero at the same time. CEO Sundar Pichai compared the achievement to building the first rocket to leave the Earth’s atmosphere and touch the edge of space, an advance that brought interplanetary travel into the realm of the possible.
In their experiment, the researchers were able to get 53 of the qubits — connected to each other in a lattice pattern — to interact in a so-called quantum state. HOLD ON A QUBITWhile the peer-reviewed research has drawn plaudits, with MIT’s William D. Oliver comparing its findings in Nature to the Wright brothers’ first flights, skeptics say Google is over-selling its achievement.
“Quantum computers will never reign ‘supreme’ over classical computers, but will rather work in concert with them, since each have their unique strengths,” Dario Gil, director of research at IBM, wrote in a blog.
