In the bizarre field of quantum physics, quantum entanglement, what Einstein called “creepy action at a distance,” stands out as one of the most intriguing phenomena. And now scientists have successfully demonstrated it again, this time aboard a CubeSat satellite that orbits Earth. Quantum entanglement is where two particles inextricably …
