CAMBRIDGE, Mass. – Quantum computers are computers that exploit the weird properties of matter at extremely small scales. Many experts believe that a full-blown quantum computer could perform calculations that would be hopelessly time consuming on c…
Through his participation, the research team from Bochum, Duisburg-Essen, and Hamburg now has succeeded in an energy-state occupancy readout of those artificial atoms — using common interfaces to classic computers. This is a big step towards t…
(Santa Barbara, Calif.) — — An interdisciplinary team of researchers at UC Santa Barbara has produced a groundbreaking study of how nanoparticles are able to biomagnify in a simple microbial food chain.
“This was a simple scientific curiosity…
New research by University of British Columbia physicists indicates that high-temperature superconductivity in copper oxides is linked to what they term ‘incoherent excitations’–a discovery that sheds light on the electronic response of these mater…
(Santa Barbara, Calif.) — — Physicists at UC Santa Barbara have succeeded in combining laser light with trapped electrons to detect and control the electrons’ fragile quantum state without erasing it. This is an important step toward using quantu…
Finding ways to control matter at the level of single atoms and electrons fascinates many scientists and engineers because the ability to manipulate single charges and single magnetic moments (spins) may help researchers penetrate deep into the …
SANTA CRUZ, CA–A tiny optical device built into a silicon chip has achieved the slowest light propagation on a chip to date, reducing the speed of light by a factor of 1,200 in a study reported in Nature Photonics (published online September 5 and …
Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters.
String theory was originally developed to describe the fundamental particles and forces that make up…
Researchers based at Lawrence Berkeley National Laboratory and the University of California at Berkeley have used a scanning tunneling microscope (STM) to reveal eight-fold patterns of quasiparticle interference in the high-temperature superconductor Bi-2212 (bismuth strontium calcium copper oxide).
