Quantum computer works with more than zero and one

 Quantum Physics News
 21 July 2022
We all learn from early on that computers work with zeros and ones, also known as binary information. This approach has been so successful that computers now power everything from coffee machines to self-driving cars and it is hard to imagine a life without them....

Using holograms to illuminate de Sitter space

 Quantum Physics News
 20 July 2022
Our understanding of the universe may not be expanding as much as the universe itself. In some cases, our theories about cosmic inflation may feel as if they are deflating into a black hole....

Machine learning paves the way for smarter particle accelerators

 Quantum Physics News
 19 July 2022
Scientists have developed a new machine-learning platform that makes the algorithms that control particle beams and lasers smarter than ever before. Their work could help lead to the development of new and improved particle accelerators that will help scientists unlock the secrets of the subatomic...

Researchers create order from quantum chaos

 Quantum Physics News
 19 July 2022
In a new paper in PNAS, "Triplet-Pair Spin Signatures From Macroscopically Aligned Heteroacenes in an Oriented Single Crystal," National Renewable Energy Laboratory (NREL) researchers Brandon Rugg, Brian Fluegel, Christopher Chang, and Justin Johnson tackle one of the fundamental problems in quantum...

Attosecond measurement on electrons in water clusters

 Quantum Physics News
 19 July 2022
Virtually all vital chemical processes take place in aqueous solutions. In such processes, a decisive role is played by electrons that are exchanged between different atoms and molecules and thus, for instance, create or break chemical bonds. The details of how that happens, however, are difficult...

A quantum wave in two crystals

 Quantum Physics News
 18 July 2022
Particles can move as waves along different paths at the same time—this is one of the most important findings of quantum physics. A particularly impressive example is the neutron interferometer: neutrons are fired at a crystal, the neutron wave is split into two portions, which are then superimposed...

Researchers measure rare particle decay with high precision

 Quantum Physics News
 14 July 2022
At CERN's Large Hadron Collider (LHC), studies of rare processes allow scientists to infer the presence of heavy particles, including undiscovered particles, that cannot be directly produced. Such particles are widely anticipated to exist beyond the Standard Model, and could help explain some of the...

Physicists harness quantum 'time reversal' to measure vibrating atoms

 Quantum Physics News
 14 July 2022
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks as well as quantum sensors, which are systems of atoms whose fluctuations can indicate...
