‘GAMERS’ Method Creates Unique 4-D Molecular Spectral Maps

JCP-Harel-spectrum.jpg

Researchers at Northwestern University have created a new method to extract the static and dynamic structure of complex chemical systems. In this context, “structure” doesn’t just mean the 3-D arrangement of atoms that make up a molecule, but rather time-dependent quantum-mechanical degrees of freedom that dictate the optical, chemical and physical properties of the system. They discuss their work in this week’s The Journal of Chemical Physics.

Why Study in Femtoseconds?

The text on this screen may appear stable enough, but every molecule, atom, and electron in it is in constant motion. The laws of quantum physics require that on the atomic scale nothing is ever truly at rest. Nano-sized motion also keeps us warm, cooks our food, lights our smartphones, and enables all of our senses of hearing, sight, smell, taste, and touch.

‘Indistinguishable Photons’ Key to Advancing Quantum Technologies

Indistinguishable photons are critical for quantum information processing, and a group of researchers in Japan is tapping nitrogen impurity centers found within gallium arsenide to generate them -- making a significant contribution toward realizing a large number of indistinguishable single-photon sources.

The Inner Lives of Molecules

JCP-Hockett-molecule-images.png

Researchers from Canada, the U.K. and Germany have developed a new experimental technique to take 3-D images of molecules in action. This tool can help scientists better understand the quantum mechanics underlying bigger and more complex molecules. They describe their work in this week’s The Journal of Chemical Physics.

In a Quantum Race Everyone Is Both a Winner and a Loser

Walther_quantum_switch_C_Jonas_Schmle.jpg

Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical physics apply. However, in the quantum world orders can be ‘scrambled’. It is possible for different orders of quantum operations to coexist in a superposition. The current work by a team of physicists from the University of Vienna and the Austrian Academy of Sciences is the first experimental quantification of such a superposition. It will be published in an upcoming issue of "Science Advances".

Roger Penrose Institute to Form in San Diego

SRPenrose.jpg

A unique institute is being formed to develop and investigate the forward-thinking ideas of eminent British physicist Sir Roger Penrose. To be based in San Diego, California, with collaborations in London and Oxford in the UK, and Tucson, Arizona, the Institute will examine the interplay between quantum mechanics and general relativity and the possible implications on our understanding of consciousness.
