How to make a quantum bit

We have looked at how a transistor works, the fundamental unit of classical computers, and how a quantum computer works in theory, taking advantage of quantum superposition to hold exponentially more information than classical computers. Now we look at the practical side of making a quantum bit, or qubit. How do you put it in a state where it is stable? How do you read and write information on it? These processes are described for a solid state qubit – a phosphorous atom in a silicon crystal substrate. Both the electron and the nucleus of the phosphorous atom can be used as qubits.

Amazing Albino Animals (24 pictures)

Given the millions of different shades of color that we see in nature, it’s no wonder that, once in a while, nature might simply run out of paint. Perhaps this is why pure-white animals leave such a strong impression on us.
