Cooper Pair Induced Quasiparticles Form Gapless Superconductor

A team of researchers from China and the United States has recreated gapless superconducting quasiparticles on fragmented Fermi surfaces of bismuth telluride (Bi2Te3) thin films. An in-plane magnetic field leads to finite-momentum Cooper pairing on the topological surface states of bismuth telluride.

Researchers Demonstrate the Viability of a “Quantum Entanglement Witness” in Solid Materials

Quantum entanglement occurs when two particles appear to communicate without a physical connection, a phenomenon Albert Einstein famously called "spooky action at a distance." Nearly 90 years later, a team led by the U.S. Department of Energy's Oak Ridge National Laboratory demonstrated the viability of a "quantum entanglement witness" capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material.

Excess Entanglement Hinders the Training of Quantum Machine Learning Models

A group of international researchers have discovered an important barrier that prevents quantum machine learning from being trained – too much quantum entanglement.

Four-Particle Electron Family Forms Formerly Unidentified State of Matter

Dissipationless electric energy transport—also called superconductivity—is considered an inspiration for the energy sector. Since its discovery over a century ago, researchers globally have been exploring this distinguished quantum occurrence, which, however, needs the electrons in metals to be cooled to ultra-low temperatures.

First Experimental Reconstruction of a Bloch Wavefunction

Lightspeed is the fastest velocity in the universe. Except when it isn't. Anyone who's seen a prism split white light into a rainbow has witnessed how material properties can influence the behavior of quantum objects: in this case, the speed at which light propagates.
