Experimental and theoretical physicists from the Würzburg Institute for Topological Insulators have observed a re-entrant quantum Hall effect in a mercury telluride device and have identified it as a signature of parity anomaly....

Scientists published the Cascaded Variational Quantum Eigensolver (CVQE) algorithm in a recent article, expected to become a powerful tool to investigate the physical properties in electronic systems....

Researchers have brought together two Nobel prize-winning research concepts to advance the field of quantum communication. Scientists can now efficiently produce nearly perfect entangled photon pairs from quantum dot sources....

Scientists made a single-molecule transistor using quantum interference to control electron flow. This new design offers high on/off ratio and stability, potentially leading to smaller, faster, and more energy-efficient devices. Quantum interference also improves the transistor's sensitivity to...

Entanglement is what Einstein called "spooky action at a distance." It is a key part of what distinguishes quantum mechanics from our everyday experience. In quantum mechanics, scientists use a measurement called entanglement entropy to quantify the amount of the entanglement between two...

In a new study, scientists propose the concept of "virtual quantum broadcasting," which provides a workaround to the longstanding no-cloning theorem, thereby offering new possibilities for the transmission of quantum information....

The 2023 Nobel Prize in Chemistry was focused on quantum dots -- objects so tiny, they're controlled by the strange rules of quantum physics. Quantum dots used in electronics are often toxic, but their nontoxic counterparts are being explored for uses in medicine and in the environment, including...

Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this...

Magnetic moment is an intrinsic property of a particle with spin, arising from interaction between the particle and a magnet or other object with a magnetic field. Like mass and electric charge, magnetic moment is one of the fundamental magnitudes of physics....

Scientists have for the first time created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analog black holes behave and interact with their surroundings....
