This isn\'t right. It isn\'t even wrong.

- Wolfgang Pauli, on a paper submitted by a physicist colleague

Do we understand quantum computing?
quantum introduction very small
Quantum introduction (very small)
  • Concepts
    • Superposition
    • Entanglement
      • observer effect
    • Qubit
  • “If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.”
    • Niels Bohr
quantum computing 1
