The characterization of the system indicated a couple of major limits, though. Cat qubits make bit flips extremely unlikely, but not impossible. By focusing error correction only on phase flips, any bit flips that do occur inescapably trigger the failure of the entire logical, error-corrected qubit. “Achieving long logical bit-flip times is challenging because any ..

Testing the teas Scanning electron microscope image of black tea leaves, magnified by 500 times. Black tea, which is wilted and fully oxidized, exhibits a wrinkled surface, potentially increasing the available surface area for adsorption. Credit: Vinayak P. Dravid Group/Northwestern University To test their hypothesis, the authors purchased Lipton and Infusions commercial tea bags, as ..
Benefits and a non-existent risk Using an adjusted odds ratio, the researchers found that vaccination reduced the likelihood of developing long COVID with one or more symptoms by 57 percent, and reduced the likelihood of developing long COVID with two or more symptoms by 73 percent. Vaccination prior to infection was also linked to a ..
In the 1990s, Lane, as NSF director, ushered in the requirement that, in addition to intellectual merit, reviewers should consider a grant proposal’s “broader impacts.” In general, he said, the aim was to encourage science that would benefit society. The broader impacts requirement remains today. Among other options, researchers can fulfill it by including a ..
Found in the forests of Papua New Guinea, Indonesia, and Eastern Australia, birds of paradise are famous for flashy feathers and unusually shaped ornaments, which set the standard for haute couture among birds. Many use these feathers for flamboyant mating displays in which they shape-shift into otherworldly forms. As if this didn’t attract enough attention, ..
To find out how much force a mantis shrimp’s dactyl clubs can possibly withstand, the researchers tested live shrimp by having them strike a piezoelectric sensor like they would smash a shell. They also fired ultrasonic and hypersonic lasers at pieces of dactyl clubs from their specimens so they could see how the clubs defended ..
The nine-engine first stage for Isar Aerospace’s Spectrum rocket lights up on the launch pad on February 14. Credit: Isar Aerospace Isar builds almost all of its rockets in-house, including Spectrum’s Aquila engines. “The flight will be the first integrated test of tens of thousands of components,” said Josef Fleischmann, Isar’s co-founder and chief technical ..
In their testing, they use a couple of unusual electrode materials, such as a chromium oxide (Cr8O21) and an organic polymer (a sulfurized polyacrylonitrile). Both of these have significant weight advantages over the typical materials used in today’s batteries, although the resulting batteries typically lasted less than 500 cycles before dropping to 80 percent of ..

Crafty cuttlefish employ several different camouflaging displays while hunting their prey, according to a new paper published in the journal Ecology, including mimicking benign ocean objects like a leaf or coral, or flashing dark stripes down their bodies. And individual cuttlefish seem to choose different preferred hunting displays for different environments. It’s well-known that cuttlefish ..
