==========
A classical computer performs operations using classical bits, which can be either zero orone. Now in contrast, a quantum computer users quantum bits or qubits. And they can be bothzero and one at the same time. And it is this that gives a quantum computer its superiorcomputing power.There are a number of physical objects that can be used as a qubit. A single photon, anucleus or an electron. I met up with researchers who were using theoutermost electron in phosphorous as a qubit. But how does that work? Well, all electronshave magnetic fields, so they are basically like tiny bar magnets. And this property iscalled spin. If you place them in a magnetic field they will align with that field, justlike a compass needle lines up with the magnetic field of the earth.Now...
