Now in PRL! We showed how a trapped-ion quantum network node can be made more robust and versatile by adding a second atomic species. We demostrate that we can keep ion-photon entanglement alive for more than 10 seconds! journals.aps.org/prl/abstrac… @OxfordPhysics @QCSHub

Research published in Nature today explains how, for the first time, QCS researchers have experimentally implemented a type of quantum cryptography considered to be the "ultimate,” “bug-proof” means of communication. qcshub.org/device-independen… #uknqtp @EPSRC #quantum #cryptography
One of the two ion traps used, seen in the centre of the image. Around the trap run a number of laser beam lines for the preparation and manipulation of the ions. At the front of the trap, the end of the quantum network link to the other trap — an optical fibre — is visible. (Photo: David Nadlinger/ University of Oxford)

Got trust issues? (…regarding your quantum devices?) Our demo of device-independent quantum key distribution (#diqkd) is now out in Nature: "Experimental quantum key distribution certified by Bell's theorem", nature.com/articles/s41586-0… ("free" link: rdcu.be/cSvl4) 1/4
Artist's impression of device-independent quantum key distribution. Both parties control a quantum "box", where a key is assembled bit by bit from measurements on entangled atoms. Optical fibres link the boxes to a central station for the heralded creation of entanglement. (Illustration: Enrique Sahagún/Scixel.)

One of our ion trap quantum network nodes. The vacuum chamber housing the ion trap, in the centre, is surrounded by a number of laser beam lines that control a single atom confined at the centre of the trap. At the front, the end of the quantum network link connecting it to the other node – an optical fibre – is visible.

Want to read an insane tenure denial story? I was denied tenure at MIT in 2018. I was the only Hispanic faculty at my department, had 13k+ citations, 2 books, & papers in Nature, Science, & PNAS. I was never given a reason & the only letter I got told me to check the website./1🧵
