Why Did NASA and Others Spend Millions on This Quantum Computer?

Quantum computers are probably the most misunderstood of nascent technologies, which makes sense, because their very basics rely on the hardest-to-grasp concepts of physics. That’s led to people making some ridiculous claims, like that they give you “god-like powers” and that they’re an “imminent threat.” Read More >>

Why Experts Are Sceptical of IBM’s New Commercial Quantum Computer

IBM has announced the release of Q System One, or as the IBM team described it, “the world’s first fully integrated universal quantum computing system designed for scientific and commercial use.” Read More >>

US Passes Bill to Inject £950 Million Into the Quantum Tech Race

Earlier this month, American president Donald Trump signed a bill providing over a billion dollars in funding to quantum research. Read More >>

It’s Time to Plan for How Quantum Computing Could Go Wrong, Say Entrepreneurs and Physicists

Quantum computers that can crack our strongest encryption methods might be decades away – but a group of entrepreneurs and researchers think we better start talking ethics now. Read More >>

We Must Prepare Now for Quantum Attacks, National Academy of Sciences Warns

The road ahead is rocky for those hoping to build quantum computers, according to a new report from the National Academy of Sciences. But as these computers become possible, the government should prioritize preparing for the potential consequences, which could be dire for cybersecurity. Read More >>

Scientists Worldwide Are Getting Serious About Quantum Internet

It takes little more than logging on to see the flaws in today’s internet—mainly, how easy it is to steal or intercept data. One future solution for these problems could be an upgrade that relies on the latest advances in the science of subatomic particles: a quantum internet. Read More >>

There’s Now a Proven Way for Quantum Computers to Beat Classical Computers – With a Catch

Entrepreneurs and physicists are pursuing a new kind of computer—one based on the physics of the subatomic particles—that promises to revolutionise various fields. Presumably, such a quantum computer should offer some advantage over the classical computers we already use, right? The trouble is, it’s unclear what tasks quantum computers can definitively perform better than regular computers. Read More >>

How Quantum Memory Could Change Computing

In a hot tub in 2012, physicist Seth Lloyd pitched a quantum internet application to Google’s Sergey Brin and Larry Page. He called it Quoogle: a search engine that, using mathematics based on the physics of subatomic particles, returns results without ever actually knowing the query. Such an advance would require an entirely new kind of memory, called qRAM, or quantum random access memory. Read More >>

Google’s New Cirq Project Aims to Make Quantum Computers Actually Useful

Early this year, we reported that a new era of quantum computing is upon us: the NISQ, or Noisy Intermediate Scale Quantum era, in which quantum computers are still small and error prone, but they actually do something valuable. That second part is still somewhat aspirational, though, so companies like Google are offering frameworks so the public can develop useful algorithms for quantum computers. Read More >>

New Quantum Computer Milestone Would Make Richard Feynman Very Happy

A commercially available “quantum computer” has been on the market since 2011, but it’s controversial. The D-Wave machine is nothing like other quantum computers, and until recently, scientists have doubted that it was even truly quantum at all. But the company has released an important new result, one that in part realises Richard Feynman’s initial dreams for a quantum computer. Read More >>

IBM Is Teaming Up With a Bunch of Quantum Computing Startups

Quantum computers are currently best at doing a subset of tasks that regular computers can also do, except in a more expensive, esoteric, and inaccurate way. But this won’t be the case for much longer, as the field of quantum computing continues to hit new milestones. And a new partnerships between IBM and some promising startups could help quantum computers reach their full potential sooner. Read More >>

How Will Microsoft’s Wild Electron-Splitting ‘Topological’ Quantum Computer Actually Work?

Microsoft recently announced a quantum-computing advancement: a measurement that looks like an electron split in half in a piece of wire. It will be of central importance if the company hopes to create a working quantum computer. Read More >>

Google Unveils Largest Quantum Computer Yet, but So What?

Google announced its newest 72-qubit quantum computer, called Bristlecone, at a conference and in a blog post yesterday. That’s a big step over the competition—but how big a deal is it? Read More >>

What’s With All The Dental Floss in IBM’s Quantum Computers?

On a large plot of land beneath circling turkey vultures an hour north of New York City sits a crescent-shaped building. Inside of it are some of the world’s most cutting-edge quantum computers, stored in dilution refrigerators about the right size to hold an adult human. And beside one of those setups, atop a large plastic roller, was REACH dental floss—a crucial scientific tool. Read More >>
