Novel Quantum States of Exciton–Floquet Composites: Electron–Hole Entanglement and Information

Unprecedented Real-Time Capture of Quantum Information

Korean researchers from DGIST and UNIST have achieved a significant breakthrough in quantum information technology by discovering a novel quantum state called the exciton-Floquet synthesis state. The collaborative research team, led by Professor Jaedong Lee […]

EPFL scientists have built a compact waveguide amplifier by successfully incorporating rare-earth ions into integrated photonic circuits.

Breakthrough in integrated photonics

Scientists at EPFL, Switzerland, have built a compact waveguide amplifier by successfully incorporating rare-earth ions into integrated photonic circuits. The device produces record output power compared to commercial fiber amplifiers, a first in the development […]

Quantum Computer programming basics

Los Alamos National Laboratory recently published a Quantum Computer programming guide in ACM Transactions on Quantum Computing. For would-be quantum programmers scratching their heads over how to jump into the game as quantum computers proliferate and become publicly […]

If a photon carries too little energy, it does not fit inside a proton (left). A photon with sufficiently high energy is so small that it flies into the interior of a proton, where it 'sees' part of the proton (right). Maximum entanglement then becomes visible between the 'seen' and 'unseen' areas. Credit: IFJ PAN

Interior of protons is maximally entangled

Fragments of the interior of a proton have been shown by scientists from Mexico and Poland to exhibit maximum quantum entanglement. The discovery, already confronted with experimental data, allows us to suppose that in some […]

Quantum Advantage

Race Not Over Between Classical and Quantum Computers

In the race to achieve the coveted “advantage” of a quantum computer, those developing quantum algorithms are pitted against each other and against those working on classical algorithms. With each potential claim of such an […]

A new kind of superconductivity: Kagome metals

In the past four years scientists have discovered metals whose crystal structure mimics that of a traditional Japanese woven bamboo pattern: kagome metals. The international research activity in this new direction of quantum materials has […]
