Researchers realize efficient generation of high-dimensional quantum teleportation
Jan 11, 2021 (SPX)
To transmit unknown quantum states from one location to another, quantum teleportation is one of the key technologies to realize the long-distance transmission....
Scientists entangle atoms using heat
Jan 08, 2021 (UPI)
The discovery, recounted Friday in the journal Nature Communications, promises to accelerate the development of everyday quantum devices. Quantum entanglement d...
Astronomers agree: Universe is nearly 14 billion years old
Jan 05, 2021 (SPX)
The new estimate matches the one provided by the standard model of the universe and measurements of the same light made by the Planck satellite. This adds a fre...
Sustained teleportation of quantum information achieved in test
Jan 01, 2021 (UPI)
The breakthrough, described this month in the journal PRX Quantum, suggests a viable quantum internet could soon be a reality. "Quantum teleportation is essenti...
Ripples in space-time could provide clues to missing components of the universe
Dec 31, 2020 (SPX)
A new paper co-authored by a University of Chicago scientist lays out how this might work. Published Dec. 21 in Physical Review D, the method depends on finding...
Primordial black holes and the search for dark matter from the multiverse
Dec 30, 2020 (SPX)
Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed s...
Mapping out a transient atom
Dec 23, 2020 (SPX)
It was the very first user experiment carried out at European XFEL's Small Quantum System (SQS) instrument. The scientists used high-resolution electron spectro...
A blazar in the early universe
Dec 23, 2020 (SPX)
In this image, the brightest radio emission comes from the galaxy's core, at bottom right. The jet is propelled by the gravitational energy of a supermassive bl...
On the Hunt for a Missing Giant Black Hole
Dec 22, 2020 (SPX)
This missing black hole should be in the enormous galaxy in the center of the galaxy cluster Abell 2261, which is located about 2.7 billion light years from Ear...
Baghdad's wristwatch repairman is a timeless treasure
Dec 22, 2020 (AFP)
The dusty display window on Rasheed Street features a single row of classic watches in their felt boxes right at the front, with a mountain of haphazardly piled...
World first discovery confirms model of the evolution of our Universe
Dec 21, 2020 (SPX)
Published in Astronomy and Astrophysics, this research led by the University of Bonn, was the result of a collaboration between an Australian-led team of scient...
Multi-messenger astronomy offers new estimates of neutron star size and universe expansion
Dec 18, 2020 (SPX)
"We studied signals that came from various sources, for example recently observed mergers of neutron stars," said Ingo Tews, a theorist in Nuclear and Particle ...
New type of atomic clock keeps time even more precisely
Dec 17, 2020 (SPX)
Still, they could be even more precise. If atomic clocks could more accurately measure atomic vibrations, they would be sensitive enough to detect phenomena suc...
Ultracold atoms reveal a new type of quantum magnetic behavior
Dec 17, 2020 (SPX)
In experiments with ultracold lithium atoms, the researchers observed different ways in which the spins of the atoms evolve. Like tippy ballerinas pirouetting b...
Major upgrade to Fermilab accelerator complex gets green light
Dec 17, 2020 (SPX)
The approval, known as Critical Decision 2 or CD-2, is an endorsement of Fermilab's detailed, formal plan for building the PIP-II accelerator, a high-power, sup...
The farthest galaxy in the universe
Dec 16, 2020 (SPX)
We've all asked ourselves the big questions at times: "How big is the universe?" or "How and when did galaxies form?" Astronomers take these questions very seri...
Quantum interference in time
Dec 15, 2020 (SPX)
Bosons - especially photons - have a natural tendency to clump together. One of the most remarkable experiments that demonstrated photons' tendency to coalesce ...
Ball Aerospace supports PDR for NASA Spherex mission
Dec 11, 2020 (SPX)
Ball is responsible for building the spacecraft and telescope as well as system integration and test, support for integration of the spacecraft onto a launch ve...
Breakthrough in nuclear physics
Dec 10, 2020 (SPX)
The strong interaction is one of the four fundamental forces in physics. It is essentially responsible for the existence of atomic nuclei that consist of severa...
