Quantum computers can solve combinatorial optimization problems more easily than conventional methods, research shows
The traveling salesman’s problem is a classic in mathematics. A traveler is to visit N cities by the shortest route and return to the starting point. As the number N…
Researchers observe how energy of single electron is tuned by surrounding atoms
A discrete energy level of an atomic vacancy in an atomically thin material shifts upon excitation of a drum-like vibration. The temporal evolution of the localized energy level is intricately…

A new ion trap for larger quantum computers
The experimental setup of the ETH researchers. The trap chip is located inside the container underneath the silver cupola, in which a lens captures the light emitted by the trapped…
Powerful new tool ushers in new era of quantum materials research
INRS Professor Fabio Boschini and colleagues at QMI-UBC put TR-ARPES photoemission technique in the spotlight. Credit: Fabio Boschini (INRS) Research in quantum materials is paving the way for groundbreaking discoveries…
Quantum imaging could create bright future for advanced microscopes
Credit: University of Glasgow The unique properties of quantum physics could help solve a longstanding problem that prevents microscopes from producing sharper images at the smallest scales, researchers say. The…
