Researchers in Virginia Commonwealth University's Department of Physics have discovered that a technique known as nanopore sensing can be used to detect subtle changes in clusters, or extremely small chunks of matter that are bigger than a molecule but smaller than a solid.
JILA researchers have made a long-lived, record-cold gas of molecules that follow the wave patterns of quantum mechanics instead of the strictly particle nature of ordinary classical physics. The creation of this gas boosts the odds for advances in fields such as designer chemistry and quantum computing.
The Cambridge team found a way to exploit the interaction between the electron and the thousands of nuclei using lasers to 'cool' the nuclei to less than 1 milliKelvin. They then showed they can control and manipulate the thousands of nuclei as if they form a single body in unison, like a second qubit. This proves the nuclei in the quantum dot can exchange information with the electron qubit and can be used to store quantum information as a memory device.
MIT physicists now have an answer to a question in nuclear physics that has puzzled scientists for three decades: Why do quarks move more slowly inside larger atoms?
Physicists at the National Institute of Standards and Technology (NIST) have 'flash-frozen' a flat crystal of 150 beryllium ions (electrically charged atoms), opening new possibilities for simulating magnetism at the quantum scale and sensing signals from mysterious dark matter.
A Japanese research team at The University of Tokyo produced a 3-D cluster molecule based on palladium. First, they created a 'butterfly-shaped' Pd4 framewok, using an organosilicon compounds bearing the aromatic substitutents as both template and support for the palladium atoms. Then, using another template, they connected two butterfly-shaped Pd4 skeleton, via chlorine, into a Pd6 cluster based on edge-sharing tetrahedra. This strategy using organosilicons to design customized subnano-architectures may enable design of a range of functional materials and catalysts.
A careful re-analysis of data taken at DOE's Jefferson Lab has revealed a possible link between correlated protons and neutrons in the nucleus and a 35-year-old mystery. The data have led to the extraction of a universal function that describes the EMC Effect, the once-shocking discovery that quarks inside nuclei have lower average momenta than predicted, and supports an explanation for the effect.
Imagine being stuck inside a maze and wanting to find your way out. How would you proceed? The answer is trial and error. This is how traditional computers with classical algorithms operate to find the solution to a complex problem. Now consider this: What if, by magic, you were able to clone yourself into multiple versions so that you were able to go through all the various paths at the same time? You'd find the exit almost instantly.
A new Tel Aviv University study explores the activity of quantum particles in 2D materials within an unprecedented small time frame and at an extraordinarily high spatial resolution. These are highly sought-after capabilities for advanced communications technologies and for photonics-based quantum computers.
Recently, Dr. ZHOU Yan and Prof. SHEN Wenjie at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences and their collaborators identified the atomic structure of the catalytically active copper-ceria interface and proposed a copper bilayer model.
