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.
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.
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.
Wanna see what a super-futuristic quantum computer lab looks like? Press play and sit back.
Someday, somehow, quantum computing is going to change the world as we know it. Even the lamest quantum computer is orders of magnitude more powerful than anything we could ever make today. But figuring out how to program one is ridiculously hard.
What's better than a quantum computer? A quantum computer in a diamond, duh. And if you're asking why we need a quantum computer inside a diamond, well, may god have mercy on your joyless soul.
It's completely counterintuitive, but scientists at the Niels Bohr Institute have succeeded in cooling a semiconductor membrane to −452.2°F, almost seven degrees above absolute zero, using a powerful laser we usually think of as only being able to burn.
The core advantage of quantum computing — the ability to compute for many possible outcomes at the same time and therefore crunch data much more quickly than classical computers — also creates a problem for data security.
The uncertainty principle is at the foundation of quantum mechanics: You can measure a particle's position or its velocity, but not both. Now it seems that quantum computer memory could let us violate this rule.
A new device uses optical fibers to measure light from individual ions. Since these charged atoms store quantum information, this ion trap could allow us to build practical quantum computers and to link light and matter at the quantum level.
One big problem holding up the development of quantum computing is building materials. But there might be a solution, and it awesomely involves nitrogen-infused diamond nanocrystals.
Ah, quantum computing. When will all your magical, paradigm-shifting awesomeness arrive and save us all from the ubiquitous 1's and 0's that define our computing day? What's this? A "Mainz interface?" What's that?
It only measures seven atoms but, according to project lead scientist Michelle Simmons, computers made with this transistor—the smallest ever made—will "solve problems that would take longer than the life of the universe with a classical computer."
The quantum computer that many—us included—doubted would ever materialize showed up yesterday. However, I think it's fair to say that we're a little disappointed with what actually materialized. Sure, the hack thing to do is to praise its ability to solve Sudoku puzzles, but to me there's quite a difference between…
You know what today is? Well, allegedly, it's quantum computer unveiling day! ABC has a story reminding us that today is the day that that Canadian company is supposed to unveil the world's first quantum computer and peppers it with all sorts of "how will this change your life?" scenarios.
