At the core of quantum computing is the qubit. The best ones have a few defining traits, and scientists are looking to everything from lasers to Russian diamonds to help refine the best qubits for the next generation of quantum computing.
Doctors say some lymphoma patients are being completely cured in a way “never been seen before”.
A team of researchers from the University of Glasgow, the University of Strathclyde and Hobart and William Smith Colleges has developed a new coating for mirrors used on gravity detectors that is 25 times less noisy than mirror surfaces used on LIGO. In their paper published in the journal Physical Review Letters, the group describes how they made it and how well it performed during testing.
The mirrors used in gravity wave detectors are positioned at the ends of its arms. Coherent light rays are reflected from both mirrors and interfere with each other. Gravitational waves are measured by noting how much the mirrors shift, resulting in slight changes in length of the arms to which they are attached, to an accuracy of 10–16 cm. As impressive as that is, researchers want to improve the sensitivity of the detectors used at LIGO/Virgo, even after the recent upgrade.
To that end, members of the European Union have begun developing plans for the construction of what the Einstein Telescope, a gravitational wave detector with sensitivity 100 times higher than LIGO/Virgo. But for that to happen, improvements in the design of the current interferometer are required. One of those improvements is reducing the amount of thermal fluctuations in the mirror coatings. In this new effort, the researchers claim to have done just that.
The Nobel Museum in Stockholm has been gifted Albert Einstein’s first paper published after he received the Nobel Prize in 1922 and discussing his then still controversial relativity theory.
Swedish businessman Per Taube bought the handwritten two-page document at an auction for 1.2 million krona (110,000 euros) in December last year.
He has now made good on his promise to gift the manuscript to the Nobel Museum, which will put it on display in a glass frame this autumn.
For as smart as artificial intelligence systems seem to get, they’re still easily confused by hackers who launch so-called adversarial attacks — cyberattacks that trick algorithms into misinterpreting their training data, sometimes to disastrous ends.
In order to bolster AI’s defenses from these dangerous hacks, scientists at the Australian research agency CSIRO say in a press release they’ve created a sort of AI “vaccine” that trains algorithms on weak adversaries so they’re better prepared for the real thing — not entirely unlike how vaccines expose our immune systems to inert viruses so they can fight off infections in the future.
An international research team led by Northeastern University marine biologists has discovered a new genus and species of shipworm burrowing into the bedrock of the Abatan River on the Philippine Island of Bohol.
We’re discovering that simply worrying about aging can, in itself, lead to undue stress and premature aging, as a result. It can also shorten lifespan. In this video, author Ashton Applewhite explains.
Are you — is every person you’ve ever loved, every incredible sight you’ve ever witnessed — part of a hologram? Some scientists think so.
They argue that all the information in the universe may be stored on some sort of two-dimensional object. In this video, NASA astronomer Michelle Thaller delves into frontier science — an unchartered territory that may require a new level of physics to better understand.
