Episode notes
Einstein thought this was bizarre and spooky, because it basically breaks the laws of physics that are supposed to govern the universe. It suggests information can move between two particles faster than the speed of light, which is supposed to be impossible. The idea of entangling qubits and superpositions together is the key to the quantum computers being built today. To make qubits, Michelle Simmons uses the spin of electrons in a phosphorus atom encased in a silicon crystal. She's able to manipulate the way these electrons spin, putting them into superpositions and entangling them together. Using a special microscope, she can even see it happen. In a quantum computer, your qubits lose their
