3+ day, 20+ hour ago   (555+ words) Alex Krasnok argues that the value of a university quantum computer lies in what students learn from it The best moment in my quantum-computing class often comes when something fails. A student writes a short quantum circuit – a program that…...

4+ day, 22+ hour ago   (422+ words) The double-slit experiment is perhaps the most iconic demonstration in quantum mechanics: showing how a single particle’s wavefunction interferes with itself as it passes through two slits at once, with a tangible impact on where the particle is ultimately observed....

5+ day, 18+ hour ago   (387+ words) Maria Gragera Garcés is a PhD student contributor to Physics World. She is pursuing her PhD in distributed quantum computing at the Quantum Software Lab, University of Edinburgh, UK. Her research focuses on building software frameworks for computing systems where…...

She has more than 10 years of experience in science writing and editing in condensed-matter physics relating to technology/nanotechnology/biotechnology, astronomy and astrophysics, energy and the environment, biology and medicine. She…...

1+ week, 3+ day ago   (238+ words) Lorna Brigham is a Scientific Editor at IOP Publishing. She holds a Master’s degree in Chemistry and completed her PhD at the University of Sussex, where she specialised in photovoltaic materials. Lorna joined the Reports on Progress in Physics journal…...

2+ week, 3+ day ago   (194+ words) A quantum computer that runs itself using an internal clock can only compute accurately if that clock is precise, and that precision comes with a thermodynamic cost Most quantum computers today do not work in isolation. They rely on carefully…...

3+ week, 3+ day ago   (1318+ words) Robert P Crease attends an unusual workshop that sought to moderate the sometimes infuriating discord between physicists and journalists How many times have you wanted to throttle a journalist? Do you ever get incensed about articles, podcasts or videos that…...

3+ week, 3+ day ago   (392+ words) New research shows that sensors based on exceptional points can beat ordinary sensors in ideal quantum-limited measurements, but only if the light input, loss rate, and the perturbation being measured are carefully matched Exceptional points occur in open physical systems…...
