Nanotechnology Now Einstein-Podolski-Rosen correlations can be used for precision measurements. (Image: Jurik Peter, Shutterstock) Abstract: Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles. Quantum steering for more precise measurements Basel, Switzerland | Posted on April 23rd, 2021 In quantum information, the fictitious agents Alice and Bob are often used to illustrate complex communication tasks. In one such process, Alice can use entangled quantum particles such as photons to transmit or teleport a quantum state - unknown even to herself - to Bob, something that is not feasible using traditional communications. ....

CREDIT Photo by Jeff Fitlow/Rice University Abstract: In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect a characteristic change in the way electricity is conducted in the presence of a magnetic field in a nonmagnetic quantum material to which no magnetic field was applied. ....
Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Quantum computers to study the functioning of the molecules of life: A team of theoretical physicists from the University of Trento has shown that it is possible to use quantum computers to simulate processes of great biological importance, such as changes in the shape of protein Abstract: The human body is like a construction site where hundreds of thousands of different molecular nanomachines, called proteins, are simultaneously at work. Each one of these biomolecules, which are chains of amino acids essential to living organisms, perform a different biological function, often in synergy with other proteins. During their formation (the folding process) or in the performance of their biological functions, proteins change their shape in a very specific way. In many cases it is possible to conduct experiments that provide images of proteins at near atomic resolution, but only when they are in the stable ....
