Advancing Quantum Matter: “Golden Rules” for Building Atomic Blocks

Posted by in category: quantum physics

Physicists have developed a technique to precisely align supermoiré lattices, revolutionizing the potential for next-generation moiré quantum matter.

National University of Singapore (NUS) physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next-generation moiré quantum matter.

Atomically precise vacancy-assembled quantum antidots

Posted by in category: quantum physics

We developed a technique to fabricate atomically precise quantum antidots with unprecedented robustness and tunable quantum hole states through self-assembled single vacancies in a two-dimensional transition metal dichalcogenide.

Quantum entanglement visualized for the first time ever

Posted by in categories: particle physics, quantum physics, space

The mysterious phenomenon that Einstein once described as “spooky action at a distance” was seen as a wavefunction between two entangled photons.

Quantum physics, the realm of science that describes the Universe at the smallest scales, is known for its counter-intuitive phenomena that seem to defy every law of physics on an everyday scale.

Arguably none of the aspects of quantum physics are as surprising or as troubling as entanglement, the idea that two particles can be connected in such a way that a change to one is instantly reflected in the other, even if the two particles are at opposite sides of the Universe. It’s the word “instantly” that troubled Albert Einstein enough to describe entanglement as “spooky action at a distance”.

UChicago scientists observe first evidence of ‘quantum superchemistry’ in the laboratory

Posted by in categories: chemistry, computing, particle physics, quantum physics

A team from the University of Chicago has announced the first evidence for “quantum superchemistry” – a phenomenon where particles in the same quantum state undergo collective accelerated reactions. The effect had been predicted, but never observed in the laboratory.

The findings, published July 24 in Nature Physics, open the door to a new field. Scientists are intensely interested in what are known as “quantum-enhanced” chemical reactions, which could have applications in quantum chemistry, quantum computing, and other technologies, as well as in better understanding the laws of the universe.


Breakthrough could point way to fundamental insights, new technology.

Quantum computers could soon connect over longer distances

Posted by in categories: computing, quantum physics

A new study discusses how high-fidelity quantum information could be sent through fiber optic networks by a novel atomic device.

Did you know quantum transmissions can’t be amplified over a city or an ocean like conventional data signals? Instead, they have to be periodically repeated using specialized devices called quantum repeaters.

For the technology to be used in future communications networks, researchers have developed a novel method of connecting quantum devices over great distances.

Challenging Einstein — New Study Suggests That Dark Matter Interacts With Gravity in a Non-Local Way

Posted by in categories: cosmology, quantum physics

Isaac Newton described his theory of gravity as a force that acts instantaneously across space: a planet immediately senses the effects of another astronomical object, regardless of the separation between them. This aspect inspired Einstein to create the renowned theory of general relativity, where gravity becomes a local deformation of spacetime.

The principle of locality states that an object is directly influenced only by its surrounding environment: distant objects cannot communicate instantaneously, only what is here right now matters. However, in the past century, with the birth and development of quantum mechanics, physicists discovered that non-local phenomena not only exist but are fundamental to understanding the nature of reality.

Now, a new study from SISSA – Scuola Internazionale Superiore di Studi Avanzati, recently published in The Astrophysical Journal.

Waves of Entanglement Seen Rippling Through a Quantum Magnet For The First Time

Posted by in categories: quantum physics, space

Crafting organic molecules into a bizarre kind of magnet, physicists from Aalto University and the University of Jyväskylä in Finland have created the perfect space for observing the elusive activity of an electronic state called a triplon.

Where a garden variety magnet is typically best described as having two poles surrounded by a nest of field lines, the curious construct known as a quantum magnet defies such a simple description.

As is the case any time the word ‘quantum’ appears, you can imagine a landscape where nothing is certain. Like spinning roulette wheels in a dimly lit casino, all states are a maybe until the croupier says “no more bets”.
