We present some applications of high-efficiency quantum interrogation (interaction-free measurement) for the creation of entangled states of separate atoms and of separate photons. The quantum interrogation of a quantum object in a superposition of object-in and object-out leaves the object and probe in an entangled state. The probe can then be further entangled with other objects in subsequent quantum interrogations. By then projecting out those cases in which the probe is left in a particular… Expand

Towards practical design rules for quantum communications and quantum imaging devices
A common syndrome in much of the current quantum optics and quantum computing literature is the casual switching between classical concepts (e.g., geometric rays, electromagnetic waves) and quantumExpand
Nondestructive interaction-free atom-photon controlled-NOT gate
We present a probabilistic (ideally 50%) nondestructive interaction-free atom-photon controlled-NOT gate, where nondestructive means that all four outgoing target photon modes of the gate areExpand
Universal quantum computation with shutter logic
We show that universal quantum logic can be achieved using only linear optics and a quantum shutter device. With these elements, we design a quantum memory for any number of qubits and a CNOT gateExpand
A general framework is presented to study nondistortion quantum interrogation (abbreviated NQI) in which process the unknown internal state of the quantum object being detected is not disturbed. TheExpand
