Okay, so when we talk about classical systems, our description of the configuration of the different states is given by a probability. So I might say my bit is a mixture of 50% 0 and 50% 1. Now when we move to quantum theory we no longer have probabilities but instead have complex numbers. But what symbol am I supposed to use for this? My state is a mixture of 1\/sqrt(2) q% 0 and 1\/sqrt{2} q% 1? Mabye we should invent a new symbol which is the % sign but with the slash the other direction? Or turn those 0s in the % sign into “q”s?<\/p>\n","protected":false},"excerpt":{"rendered":"
