A quantum machine has used entangled qubits to generate a number certified as truly random for the first time, demonstrating a handy function that’s physically beyond even the most powerful supercomputer.

Researchers from the US and UK repurposed existing quantum supremacy experiments on Quantinuum’s 56-qubit computer to roll God’s dice. The result was a number so random, no amount of physics could have predicted it.

Quantum technology is becoming critical for secure electronic communication as cybersecurity threats increase.

Biological systems, once thought too chaotic for quantum effects, may be quietly leveraging quantum mechanics to process information faster than anything man-made.

New research suggests this isn’t just happening in brains, but across all life, including bacteria and plants.

Schrödinger’s legacy inspires a quantum leap.

Researchers have discovered an unexpected superconducting transition in extremely thin films of niobium diselenide (NbSe2). Publishing in Nature Communications, they found that when these films become thinner than six atomic layers, superconductivity no longer spreads evenly throughout the material, but instead becomes confined to its surface.

This discovery challenges previous assumptions and could have important implications for understanding and developing advanced quantum technologies.

Researchers at the Hebrew University of Jerusalem have made a surprising discovery about how superconductivity behaves in extremely thin materials. Superconductors are materials that allow electric current to flow without resistance, which makes them incredibly valuable for technology. Usually, the properties of superconductors change predictably when the materials become thinner; however, this study found something unexpected.

Quantum critical points are thresholds that mark the transition of materials between different electronic phases at absolute zero temperatures, around which they often exhibit exotic physical properties.

One of these critical points is the so-called Kondo-breakdown quantum critical point, which marks the collapse of the Kondo effect (i.e., that entails the localization of magnetic moments in metals), followed by new emergent physics.

Researchers at Ludwig-Maximilian University of Munich, Rutgers University, and Seoul National University set out to further study the dynamical scaling associated with the Kondo-breakdown quantum critical point, utilizing a describing heavy fermion materials known as the periodic Anderson model.

A quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.

The impressive demonstration by researchers in the US in 2024 may not help you beam to work to beat the morning traffic, or download your favourite cat videos faster.

However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.
