Here are my solutions including generalizations. You can see a video (sorry that it is a bit shaky) at mathinst.com/clockHandsDSTstart of my clock auto-updating a few minutes ago. #mathisfun #mtbos #iteachmath #DST #DaylightSavingsTime #atomicClocks

I came up with a #mathisfun problem about #DST #DaylightSavingsTime & #atomicClocks. A few mins ago at the beginning of DST, my analog wall clock updated itself w/ clock arms moving at a faster rate than usual. If they go 6x the regular rate, how long would it take to add an hour? #mtbos #iteachmath

One news item, that nobody reported on last year is, that we now have three optical transitions measured to just 1e-16 (88Sr+), 1.8e-16 (87Sr) and 1.9e-16 (171Yb).

This means, that we now have three atom species that can be used for optical clocks, whose uncertainty is below what the […]

Is the Single Strontium Atom Photo Real? The single strontium atom photo is real. It shows a single, laser-cooled Sr+ ion held between electrodes in an ion trap and made to glow by laser-induced fluorescence, which a standard camera can record in a long exposure. You are seeing light scattered by that atom, not a resolved image of its physical size or structure. What is the single strontium atom photo?

Ever seen a photo of a single atom? That tiny speck is a laser-cooled Sr+ ion floating between electrodes—captured on camera! Wild, right? What part of this blows your mind most? #atomicclocks #iontrap #lasercooling #quantumcomputing #singlestrontiumatom

Coming back to OSHW atomic clocks. After thinking for a while. I think the cheapest option is to build a 87 Rb vapor cell coherent population trapping clock. I.e. one that shines a laser onto a vapor cell, which is modulated with half the hyperfine splitting.

The only special part needed would […]

Most of my clocks DIY #AtomicClocks or internet connected.

Stove, old school red LED clock in office, and truck (maybe) are manual.

Entanglement at Telecom Wavelengths: A Roadmap for Distributed Quantum Computing Quantum networks promise to revolutionize secure communication, distributed computing, and atomic clock synchronization. However, most systems based on atoms or ions work at visible or ultraviolet wavelengths, which do not propagate well in the optical fibers used in telecommunications. To connect distant quantum nodes, photons must be converted to bands around 1.3–1.5 µm, a process that introduces losses and noise.

Researchers achieved telecom-band entanglement with ytterbium-171, a milestone for quantum networks. #Quantum #Telecom #Entanglement #AtomicClocks #QuantumComputing
