3+ day, 3+ hour ago   (218+ words) One of the major challenges was simply doing precision optical experiments outdoors, he adds. “We had to contend with the unpredictability of nature: changes in sunlight and temperature, wind, rain and even the thermal expansion of buildings, which can affect…...

4+ day, 47+ min 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…...

5+ day, 2+ 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....

2+ week, 4+ 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…...

2+ week, 4+ day ago   (172+ words) A fundamental physics discovery could help reduce energy losses in future wireless power technologies Wireless power transfer research tends to focus on engineering solutions such as improved coil designs, impedance matching and frequency tuning. However, in this work, the researchers…...
