IBM’s latest quantum computer is a 20-qubit work of art

Visions of an American quantum computing initiative are close to becoming a practical reality. The House of Representatives has passed its version of a bill that would establish a National Quantum Initiative Program and speed up the development of n...
Quantum computers need memory to perform tasks like their conventional counterparts, but it's hard to create that memory when it only takes nearby vibrating atoms to lose all their data. Scientists may have a clever solution, though: tune diamond li...
From afar, it looks like a steampunk chandelier. Or an intricate collection of tubes and wires that culminate in a small steel cylinder at the bottom. It is, in fact, one of the most sophisticated quantum computers ever built. The processor inside ha...
It's been almost three months since Intel announced a 17-qubit superconducting chip, meant to pave the way for a future powered by quantum computers. Today at CES, Intel CEO Brian Krzanich showed off its latest superconducting test chip, the 49-qubit...
One of the greatest challenges in quantum computing is... well, making the computers. You may need exotic manufacturing techniques just to handle the very exacting requirements, such as positioning the atoms in quantum bits in exact positions at clo...
Whether or not you believe Google has honest-to-goodness quantum computers, the bigger problem is their limited access: they're largely off-limits outside of the company itself. That could change sooner than you think, though. Bloomberg sources under...
Scientists already believe that diamonds could be a solid foundation for practical quantum computers. You can use atom-scale defects in diamond to store quantum bits that hold contradictory data (say, both on and off) in a way that lets you read the...
Companies can technically buy a quantum computer right now, but it's not really the same as a general-purpose computer. Even if you don't question whether or not it is quantum computing, it really amounts to specialized hardware. However, IBM hopes...
For the first time ever, two quantum computers have faced off against each other in a series of experiments to determine which technology reigns supreme. A team of researchers from the University of Maryland have pitted their own quantum computer aga...
