Blockchain is meant to be secure—but a new paper from quantum computing scientists warns that quickly advancing quantum technology poses a vulnerability for the much-hyped blockchain.
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.
Entrepreneurs and physicists are pursuing a new kind of computer—one based on the physics of the subatomic particles—that promises to revolutionize 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…
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…
The House of Representatives passed the National Quantum Initiative Act yesterday. When signed into law, the bill will outline a 10-year plan to push forward applications using the counterintuitive science of subatomic particles.
Last 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…
If you’ve read anything about quantum computers, you may have encountered the statement, “It’s like computing with zero and one at the same time.” That’s sort of true, but what makes quantum computers exciting is something spookier: entanglement.
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…
Your data may be safe from a quantum attack... for now. When quantum computers develop the ability to crack present-day encryption mechanisms, will you be ready?
Quantum computing might be nascent, but recent advancements have brought us into a new age. And every new era needs a name. So when future computing historians look back on the era starting around 2017, they’ll have a word to describe it: the NISQ era.
MOUNTAIN VIEW, CA—Earlier this week, representatives from automotive and airline companies, big banks, software companies, and the military met to learn the basics of quantum mechanics at NASA. And that was only a small part of it.
IBM has announced two powerful new quantum computer processors, one client-ready and another in the works.
They will never sit on your desk, and they will most certainly never fit in your pocket. Today, they’re fragile, and need to be kept at temperatures close to absolute zero. Quantum computers aren’t much like the desktop PCs we’re all so familiar with—they’re a whole new kind of machine, capable of calculations so…
For decades, quantum computing has been the preserve of research labs. But now IBM has made its working prototype quantum computer accessible via the internet—and literally anyone can use it.
Quantum computing could make complex calculations trivial—but it’s currently fraught with problems. Now, though, IBM has solved one of the biggest, allowing it to detect the internal errors that could otherwise render quantum calculation useless.
A new study claims that the D-Wave quantum computer is no faster than the PC on your desk, leading many to proclaim the technology as overhyped. Trouble is, the performance tests were too easy and not a true measure of what these machines are capable of doing.
Like graphene, quantum computing is an exciting but endlessly elusive technological promise. One of the reasons—among many—that quantum computers aren't exactly a reality yet is that we haven't been able to effectively spot errors in quantum computations. Not until now, anyway.
Earlier this year, NASA, in partnership with Google, acquired the world's largest quantum computer. But just what does the space agency plan to do with a device with such revolutionary potential? We talked to one of their lead researchers to find out.
An international team of scientists have just held a qubit's memory state for 39 minutes. That might not sound like much, but it's 100 times longer than the previous record. It's a groundbreaking achievement that could pave the way to freakishly fast computers.
