Quantum Computer Generates Truly Random Number in Scientific First

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.

The hidden superconducting state in NbSe₂: Shedding layers and gaining insights

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.

Study proposes new mechanism underpinning intrinsic strange metal behavior

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.
