Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers have used that green fluorescent protein and similar molecules to light up ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the universe in a completely different way than we do. Physicist Daniel Whiteson exp ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of physics. Despite enormous progress in cosmology and particle physics, we still ...

Henry Yuen is developing a new mathematical language to describe problems whose inputs and outputs aren’t ordinary numbers.

In our three-dimensional space, elementary particles neatly filter into either bosons or fermions. But in lower dimensions, that distinction gets a bit murky.

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

The research team used two distributed sensors and leveraged two quantum resources for increasing detection sensitivity: squeezing, characterized by reduced quantum noise below the classical optical ...
