Quantum interrogation logic gates

Understand

Quantum interrogation can be used as a basic resource for quantum information.

• This paper presents its applications to entanglement creation and to optical quantum computation.
• The starting point will be a photon to particle quantum interrogation CZ gate, from which three families of optical CNOT gates will be derived.
• These gates are nondestructive and can work with probabilities arbitrarily close to 1.
