Quantum teleportation, FLASH radiotherapy and the end of electricity from coal
Researchers have been raising the bar for quantum teleportation as Susan Curtis explains in this week’s podcast. While standard quantum teleportation has been limited to particles with just two states, the latest results set the technique on a trajectory for teleporting more complicated systems.
Also in the news this week, Margaret Harris reveals the conclusions of a study on the possible impact of visa restrictions for start-ups, who hope to attract the most suitable candidates for a highly specialized work force.
We get some of the scoop from the American Association of Physicists in Medicine (AAPM) Annual Meeting as Tami Freeman reports back on some of the topics that caught her eye, including FLASH radiotherapy, which uses high dose rates and has been producing some very encouraging results. Anna Demming brings an update from the Advanced Material Show where the prospect of bagging a bottle of chilli sauce in a giveaway finds her in conversation with a company dealing with a totally different kind of heat.
We reveal the results from our reader poll on what poses the greatest challenge to solar cells knocking coal off the hotspot for mains energy generation, and hear from global expert Martin Green who has been working in the field for more than 40 years.
And finally we wrap up with some bubble physics as Susan Curtis reports back on some spectacular soap bubbles that have attracted attention in our Red Folder.
