As described in a paper published in Nature, the JILA strontium lattice clock is some 50% more precise than the previous record holder, the NIST quantum logic clock. Engineered by the Jun Ye Group at the University of Colorado, Boulder, the strontium clock uses only a few thousand atoms of the element to help keep time.
Packed into a lattice of 100 pancake shaped traps, the JILA clock’s strontium atoms are bathed in an extremely stable red laser light, exciting them to jump between energy levels. These jumps, which occur some 430 trillion times per second, represent the quantum ticks of this hyper accurate device and result in the timepiece’s incredible performance.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
