The Grand Staircase inside Hogwarts Castle is magically whimsical, unpredictably opening up new routes while simultaneously closing others. How could this possibly be analogous to a quantum computer architecture?

🔬 EPFL researchers have collaborated with those at the Chinese Academy of Sciences on a #microscopy method that makes it possible to observe suspended cells in a more natural environment.

The scientists used two optical methods -- optical sectioning and #opticaltweezers -- to image and manipulate suspended cells in 3D. Until now, this was only possible by fixing cells to a substrate with an artificial medium.

Physicists have used lasers as #opticaltweezers to position molecules so precisely that the molecules can be used as #qubits to process #quantuminformation https://www.nature.com/articles/d41586-023-03943-1?utm_source=Live+Audience&utm_campaign=c4612ca273-briefing-dy-20231208&utm_medium=email&utm_term=0_b27a691814-c4612ca273-50179668

Very cool idea of using the dark portion of a beam and still trap. Possible due to high index of refraction of the medium. #opticaltweezers #optics

Hello everybody - here’s my #introduction.

I was a #research #scientist for many years working on #cryobiology, artificial #liver systems, #lasers, #microscopy, and #OpticalTweezers.

I now work as a #grant #funding research development manager. I spend my days reading grant applications and working with hundreds of fantastic #academics in the beautiful town of #StAndrews #Scotland.

I am interested in #sustainability and how we can make the world a better place.
