  • No I did not know.😕
  • I knew that they changed from binary to qbit. But I thought binary was one symbol and qbit was two. I don't know that much about the computing side of it. I was much more interested in entanglement and superposition. But its not easy for me to understand.
  • Quantum computers don't use the classical binary system. The binary system uses digits called "bits," which are like switches - on or off. If on=1 and off=2, you can use the switches like a rudimentary abacus to perform simple mathematical operations. The quantum computer uses "qubits" instead of bits. A qubit is like a quantum state, not like a switch. This is where grocery store checkout magazines get it all wrong. I read an article in pop sci that said that a qubit takes a value from one to fifteen or some other totally made up thing. No, qubits are variables that take a continuum of values between two extremes, but, when measured (i.e. output), they are forced to take one extreme value or the other. This is a revolutionary sort of idea, not just expanding what a computer can do, but a total paradigm shift. Computations can be done with real numbers, instead of only with bits, but the output forces the qubits into regular bits. As cool as the idea is, there are very few applications (as of 2019) where quantum computers can be utilized to outperform classical computers.
