Researchers demonstrate noise-free communication with structured light      (via sciencedaily.com)     Original source 

Scientists used a new invariant property of vectorial light to encode information. This quantity, which the team call 'vectorness', scales from 0 to 1 and remains unchanged when passing through a noisy channel.

Schrödinger's cat makes better qubits      (via sciencedaily.com)     Original source 

Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.

Physicists discover an exotic material made of bosons      (via sciencedaily.com)     Original source 

Take a lattice -- a flat section of a grid of uniform cells, like a window screen or a honeycomb -- and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the top grid a twist so that you can see portions of the lower one through it. This new, third pattern is a moiré, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors.

Calculation shows why heavy quarks get caught up in the flow      (via sciencedaily.com)     Original source 

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain experimental results showing heavy quarks getting caught up in the flow of matter generated in heavy ion collisions.

Buckle up! A new class of materials is here      (via sciencedaily.com)     Original source 

Would you rather run into a brick wall or into a mattress? For most people, the choice is not difficult. A brick wall is stiff and does not absorb shocks or vibrations well; a mattress is soft and is a good shock absorber. Sometimes, in designing materials, both of these properties are needed. Materials should be good at absorbing vibrations, but should be stiff enough to not collapse under pressure. A team of researchers from the UvA Institute of Physics has now found a way to design materials that manage to do both these things.

Finally solved! The great mystery of quantized vortex motion      (via sciencedaily.com)     Original source 

Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.

Flat fullerene fragments attractive to electrons      (via sciencedaily.com)     Original source 

Researchers have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprisingly retained and even enhanced some key chemical properties.

The 'breath' between atoms -- a new building block for quantum technology      (via sciencedaily.com)     Original source 

Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.

A nanocrystal shines on and off indefinitely      (via sciencedaily.com)     Original source 

Optical probes have led to numerous breakthroughs in applications like optical memory, nanopatterning, and bioimaging, but existing options have limited lifespans and will eventually 'photobleach.' New work demonstrates a promising, longer-lasting alternative: ultra-photostable avalanching nanoparticles that can turn on and off indefinitely in response to near-infrared light from simple lasers.

Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons      (via sciencedaily.com)     Original source 

Researchers have demonstrated a novel concept for exciting and probing coherent phonons in crystals of a transiently broken symmetry. The key of this concept lies in reducing the symmetry of a crystal by appropriate optical excitation, as has been shown with the prototypical crystalline semimetal bismuth (Bi).
