Qubits sind
gleichzeitig im
Zustand 0 und 1.
Klassische Computer
• Die Grundeinheit der Verarbeitung ist das "Bit".
• Alle klassischen Berechnungen bestehen aus der
Veränderung von Bitfolgen.
• 1-bit Befehle wie SET und NOT
• 2-bit Befehle wie AND, OR, XOR
Klassische Schaltkreise
• Die grundlegende Einheit der Information ist das Qubit.
• Qubits sind in in einer Überlagerungszustand (superpositon)
• Die Beobachtung (Measurement) eines Qubits „verwandelt“ es in
eine klassische 0 oder 1.
Quantencomputer
Quantenschaltkreise
• Alle Berechnungen bestehen aus der Veränderung von Qubit-
Sequenzen, auch Circuits genannt.
• 1-qubit Befehle wie "H", "X", "Y", and "Z"
• 2-qubit Befehle wie "CNOT" oder "SWAP"
