Large-scale quantum computers are waiting in the wings. One of the main reasons we don’t have them yet is because quantum hardware is so noisy. This isn’t the type of noise you’d want to shush in a crowded theater. When it comes to computers, noise means errors that crop up when conditions aren’t perfect.
NASA’s IXPE (Imaging X-ray Polarimetry Explorer) mission has taken a new observation of a supernova, RCW 86, helping fill in a fuller picture of what other telescopes have observed.
Body camera footage shows a Miami police officer clinging to the hood of a vehicle while firing shots at the driver who drove into him
North Andover Police Officer Patrick Noonan testified that Kelsey Fitzsimmons grabbed a gun, raised it and pulled the trigger, forcing him to shoot her
Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the sky. A special class called millisecond pulsars spins hundreds of times per second and is among the most precise clocks in the universe. For decades, astronomers believed that a pulsar’s radio signals are only produced close to the star’s surface, near its magnetic poles.
It may well take years to prove, but a pair of University of Miami astrophysicists could be on the verge of a cosmic breakthrough that will confirm the existence of primordial black holes and the role they play in one of cosmology’s greatest mysteries.
A team of scientists led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory has identified a rare, switchable quantum property in a new type of nickel sulfide material. The discovery could have applications in high-speed transistors, adaptive sensors and other devices that require a material’s electronic structure to be controlled on the fly. The research is published in the journal Matter.
An international research team led by scientists from Skoltech has developed a method to position molecules on the surface of ultrathin materials with unprecedented precision using molecular DNA self-assembly, enabling the creation of quantum light sources. The results, published in the journal Light: Science & Applications, pave the way for the production of compact and efficient components for future quantum computers and secure communication networks.
NASA’s Artemis 2 lunar mission is set to be the first crewed flyby of the moon in more than half a century, and could launch as soon as April 1.
The four astronauts selected for the Artemis 2 moon mission will be the first to travel there in more than five decades.
More than half a century after the groundbreaking Apollo program’s last crewed flight to the moon, three men and one woman are preparing for a lunar journey set to turn a new page in American space exploration.
Jason Jenkins was driving to work before dawn when a bright green streak beamed across the sky.
Scientists have created the first microlasers capable of detecting individual molecules and even single atomic ions, a breakthrough that could significantly advance early disease diagnosis and molecular-scale medical testing. Researchers at the University of Exeter’s Living Systems Institute have published their work in Nature Photonics. The paper opens up new possibilities for microlaser biosensing technology, including “lab-on-a-chip” technology capable of instant medical testing and diagnosis.
Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA’s Transiting Exoplanet Survey Satellite (TESS), a space mission that monitors the sky for the subtle dimming of starlight caused when planets pass in front of their host stars.
