Quantum spin liquid, a very rare state of matter, has been observed in a new crystal especially designed with the hopes of using its unique quantum properties.

The crystal, an ytterbium compound with the formula YbMgGaO4, was first synthesized by Chinese scientists for the first time in 2015. Now, in a new study published in the journal Nature, researchers from the United States suggest that the new material can produce a quantum spin liquid when frozen to temperatures near absolute zero. At present, only a few materials are believed to possess these properties.

Nice paper on Majorana fermions for information units in QC.

Majorana bound states in one-dimensional nanowires have attracted wide attention in recent years due to their potential use as qubits for topological quantum computation based on braiding.

Money makes the world go round, or so they say. Payments, investments, insurance and billions of transactions are the beating heart of a fractal economy, which echoes the messy complexity of natural systems, such as the growth of living organisms and the bouncing of atoms.

Financial systems are larger than the sum of their parts. The underlying rules that govern them might seem simple, but what surfaces is dynamic, chaotic and somehow self-organizing. And the blood that flows through this fractal heartbeat is data.

Today, 2.5 exabytes of data are being produced daily. That number is expected to grow to 44 zettabytes a day by 2020 (Source: GigaOm). This data, along with interconnectivity, correlation, predictive analytics and machine learning, provides the foundation for our AI-powered future.

In a new blow for the futuristic “supersymmetry” theory of the universe’s basic anatomy, experts reported fresh evidence Monday of subatomic activity consistent with the mainstream Standard Model of particle physics.

New data from ultra high-speed proton collisions at Europe’s Large Hadron Collider (LHC) showed an exotic particle dubbed the “beauty quark” behaves as predicted by the Standard Model, said a paper in the journal Nature Physics.

Previous attempts at measuring the beauty quark’s rare transformation into a so-called “up quark” had yielded conflicting results. That prompted scientists to propose an explanation beyond the Standard Model—possibly supersymmetry.

A novel quantum simulator has done what HPC’s have previously failed to do- to simulate the motion of electrons in large particle systems.

Around 75 years ago, Italian physicist Ettore Majorana hypothesized the existence of exotic particles that are their own antiparticles. Since then, interest in these particles, known as Majorana fermions, has grown enormously given that they could play a role in creating a quantum computer. Majoranas have already been described very well in theory. However, examining them and obtaining experimental evidence is difficult because they have to occur in pairs but are then usually bound to form one normal electron. Ingenious combinations and arrangements of various materials are therefore required to generate two Majoranas and keep them apart.

In Brief

• Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe.
• Physicists from CERN now believe there’s a fifth universal force that rules the behavior of dark matter, and is transmitted by a particle called the dark photon.

Astronomers have at last observed polarisation of light by virtual particles in a neutron star’s magnetic field, a long-expected quantum effect.

Ora, a Montreal-based tech start-up, has announced that it has developed the first consumer-ready graphene loudspeaker.

The company believes that graphene holds the ideal properties sought after in loudspeaker diaphragms: stiffness (graphene is stronger than diamond) and lightness (graphene is the thinnest known material, one atom thick).
