Collaborate Disseminate
Dark matter may make up the vast majority of the matter in the universe, but it’s strangely shy about making its presence known. Now, physicists have designed a new test to search for signs of two candidate particles, using the quirky world of quantum … Continue reading Quantum bits recruited to detect dark matter turning into light
Traditional computers, which perform their wonderfully quick calculations using millions of simple on/off transistors organized into logic gates, spent the last half a century getting faster and faster, to the point where we could reasonably expect the… Continue reading Landmark hot qubit research promises bigger, cheaper quantum computers
“The best-kept secret in quantum computing.” That’s what Cambridge Quantum Computing (CQC) CEO Ilyas Khan called Honeywell‘s efforts in building the world’s most powerful quantum computer. In a race where most of the major players are vying for attention, Honeywell has quietly worked on its efforts for the last few years (and under strict NDA’s, […] Continue reading Honeywell says it will soon launch the world’s most powerful quantum computer
IBM has boosted its growing stable of quantum computers with a new 53-quantum bit (qubit) device, the most powerful ever offered for commercial use. Continue reading IBM’s new 53-qubit quantum ‘mainframe’ is live in the cloud
If quantum physics always sounded a little squirrelly to you, take heart. Yale researchers have announced that they can do what quantum physics claimed to be impossible: they can determine the state a quantum system will collapse to before it happens. This contradicts Schrodinger’s famous hypothetical cat that is superimposed …read more
Researchers at Delft University of Technology have created a detector that enables the detection of a single photon’s worth of radio frequency energy. The chip is only 10 mm square and the team plans to use it to explore the relationship of mass and gravity to quantum theory.
The chip …read more
Quantum computing is coming, so a lot of people are trying to articulate why we want it and how it works. Most of the explanations are either hardcore physics talking about spin and entanglement, or very breezy and handwaving which can be useful to get a little understanding but isn’t useful for applying the technology. Microsoft Research has a video that attempts to hit that spot in the middle — practical information for people who currently work with traditional computers. You can see the video below.
The video starts with basics you’d get from most videos talking about vector representation …read more
At the American Physical Society conference in early March, Google announced their Bristlecone chip was in testing. This is their latest quantum computer chip which ups the game from 9 qubits in their previous test chip to 72 — quite the leap. This also trounces IBM and Intel who have 50- and 49-qubit devices. You can read more technical details on the Google Research Blog.
It turns out that just the number of qubits isn’t the entire problem, though. Having qubits that last longer is important and low-noise qubits help because the higher the noise figure, the more likely you …read more
Although quantum computing is still in its infancy, enough progress is being made for it to look a little more promising than other “revolutionary” technologies, like fusion power or flying cars. IBM, Intel, and Google all either operate or are producing double-digit qubit computers right now, and there are plans for even larger quantum computers in the future. With this amount of inertia, our quantum computing revolution seems almost certain.
There’s still a lot of work to be done, though, before all of our encryption is rendered moot by these new devices. Since nothing is easy (or intuitive) at the …read more
Figuring out how to route information between two different types of quantum nodes has been a significant technical barrier to the quantum net. Continue reading Researchers Created the First Hybrid Link for a Quantum Internet
