A two-atom quantum duet
Researchers at the Center for Quantum Nanoscience (QNS) within the Institute for Basic Science (IBS) achieved a major breakthrough in shielding the quantum properties of single atoms on a surface. The scientists used the magnetism of single atoms, known as spin, as a basic building block for quantum information processing. The researchers could show that by packing two atoms closely together they could protect their fragile quantum properties much better than for just one atom.

“Does the brain use quantum mechanics? That’s a perfectly legitimate question,” says Fisher. On one level, he is right – and the answer is yes. The brain is composed of atoms, and atoms follow the laws of quantum physics. But Fisher is really asking whether the strange properties of quantum objects – being in two places at once, seeming to instantly influence each other over distance and so on – could explain still-perplexing aspects of human cognition. And that, it turns out, is a very contentious question indeed.

Is quantum physics behind your brain's ability to think?
In one sense it’s obvious our brains work on quantum physics: they are made of atoms, after all. But the idea that the human brain is just a massive quantum computer is hugely controversial

Einstein's complicated relationship with Quantum Physics.
"Quantum mechanics is very impressive. But an inner voice tells me that it is not yet the real thing. The theory produces a good deal but hardly brings us closer to the secret of the Old One. I am at all events convinced that He does not play dice."

Einstein's Complicated Relationship With Quantum Physics
Most people know that Einstein eventually became dissatisfied with quantum mechanics, but before becoming disenchanted because of philosophical issues, he played a crucial role in launching the quantum theory of light.

Probing quantum physics on a macroscopic scale
Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ago. Researchers at Delft University of Technology and the University of Vienna have now devised a macroscopic system that exhibits entanglement between mechanical phonons and optical photons. They tested the entanglement using a Bell test, one of the most convincing and important tests to show a system behaves non-classically.

Neutrons probe ultra-cold condensate for insight into quantum matter
Bose-Einstein condensates are macroscopic quantum phases of matter which appear only under very particular conditions. Learning more about these phases of matter could help researchers develop a better understanding of fundamental quantum behaviors and possibly contribute to future quantum technology.

Creating the first image of a black hole was an important milestone. But in many ways, the true value of the project lies in how it created an opportunity for researchers to change the way they explore the world.
Black holes represent a moment where our universe ends and folds back upon itself, where relativity and quantum physics collide. Back here on earth, black holes do something similar - they bring people together from different disciplines to create collisions of thought.
Because black holes are the absolute boundary between what we know and what we don’t, this is a problem that cannot be solved by astronomers, physicists, or mathematicians alone. It also requires philosophers and people who can challenge researchers to think differently.
Cross-disciplinary dialogue isn’t always easy, but the Black Hole Initiative has led to a number of discussions that provide space for the unlimited possibility of collaboration.

Quantum effect observed in 'large' metal
In the world of materials science, sometimes main discoveries can be found in unexpected places. While working on the resistivity of a type of delafossite—PdCoO2—researchers at EPFL's Laboratory of Quantum Materials discovered that the electrons in their sample did not behave entirely as expected. When a magnetic field was applied, the electrons retained signatures of their wave-like nature, which could be observed even under relatively high temperature conditions and appeared in relatively large sizes. These surprising results, obtained in collaboration with several research institutions, could prove useful, for example in the quest for quantum computing. The research will be published today in the prestigious journal Science.

Controlling the electron spin: Flip it quickly but carefully
Over the past two decades, a new area at the interface of semiconductor physics, electronics and quantum mechanics has been gaining popularity among theoretical physicists and experimenters. This new field is called spintronics, and one of its main tasks is to learn how to control the spin of charge carriers in well known semiconductor structures. Many theoretical efforts are always required before some idea finds its embodiment in an actual device, and so far theoretical work on spintronics has been outweighing experimental research.

A speed limit also applies in the quantum world
Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quantum computers, among other things. They are published in the prestigious journal Physical Review X, and covered by the Physics Magazine of the American Physical Society.
