How To Make a Quantum Bit
How does a transistor work? https://www.youtube.com/watch?v=IcrBqCFLHIY Silicon-28 sphere: http://bit.ly/10J1G2o This episode supported by audible.com: http://bit.ly/ZJ5Q6z We have looked...

To find the prime factors of a 2048 number it would take a classical computer millionsof years, a quantum computer could do it in just minutes. And that is because a quantumcomputer is built on qubits, these devices which take advantage of quantum super positionto reduce the number of steps required to complete the computation.But how do you actually make a qubit in practice and how do you read and write informationon it?I met up with researchers who are using the outer most electron in a phosphorous atomas a qubit. This single phosphorous atom is embedded in a silicon crystal right next toa tiny transistor. Now the electron has a magnetic dipole called its spin. And it hastwo orientations, up or down, which are like the classical one and zero. Now to differentiatethe ene...
