Both entanglement and back-action evasion have been previously observed in macroscopic systems but in different, and arguably more limited, ways. In 2018 another group of researchers entangled two strips of silicon. Other experiments have even entangled vibrations in diamonds. Yet the tricks demonstrated by both teams in the recent Science papers have allowed them to observe quantum effects with far fewer caveats.
“We’re not discovering anything new about quantum mechanics here,” says Yiwen Chu, a quantum researcher at the Swiss Federal Institute of Technology Zurich, who was not involved in either study. But getting these measurements still requires “very impressive technological advances,” she says.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
