In the blink of an eye: Team uses quantum of light to create new quantum simulator
Imagine being stuck inside a maze and wanting to find your way out. How would you proceed? The answer is trial and error. This is how traditional computers with classical algorithms operate to find the solution to a complex ...
Questions in quantum computing—how to move electrons with light
Electronics rely on the movement of negatively-charged electrons. Physicists strive to understand the forces that push these particles into motion, with the goal of harnessing their power in new technologies. Quantum computers, ...
Life on the edge in the quantum world
Quantum physics sets the laws that dominate the universe at a small scale. The ability to harness quantum phenomena could lead to machines like quantum computers, which are predicted to perform certain calculations much faster ...
Single molecules show promise to optically detect single electrons
Optical detection of a single electron using a single molecule has never been done. Leiden physicist Michel Orrit and his team have now identified a molecule that is sensitive enough to detect an electron at a distance of ...
Breaching the horizons: Universal spreading laws confirmed
The universal laws governing the dynamics of interacting quantum particles are yet to be fully revealed to the scientific community. A team of researchers at the Center for Theoretical Physics of Complex Systems (PCS), within ...
Supercomputing helps study two-dimensional materials
Materials scientists study and understand the physics of interacting atoms in solids to find ways to improve materials we use in every aspect of daily life. The frontier of this research lies not in trial and error, though; ...
Researchers determine the performance of multi-dimensional bits
What kinds of computers would be conceivable if physics worked differently? Quantum physicists Marius Krumm from the University of Vienna and Markus Müller from the Viennese Institute of Quantum Optics and Quantum Information ...
Scientists 'hijack' open-access quantum computer to tease out quantum secrets
The rules of quantum mechanics describe how atoms and molecules act very differently from the world around us. Scientists have made progress toward teasing out these rules—essential for finding ways to make new molecules ...
IBM launches commercial quantum computing – we're not ready for what comes next
IBM recently unveiled what it claimed was the world's first commercial quantum computer. While the announcement of the Q System One wasn't scientifically groundbreaking, the fact that IBM sees this as a commercial product ...
