Using the complementary wavelike and particlelike natures of photons, it is possible to make ‘‘interactionfree’’ measurements where the presence of an object can be determined with no photons being absorbed. We investigated several ‘‘interaction-free’’ imaging systems, i.e., systems that allow optical imaging of photosensitive objects with less than the classically expected amount of light being absorbed or scattered by the object. With the most promising system, we obtained high-resolution ~10…

Experimental demonstration of exposure-free imaging and contrast amplification

Interference between waves can yield quite counterintuitive results. Some time ago, Elizur and Vaidman (1993 Found. Phys. 23 987) proposed a way to detect the presence or absence of a perfectly

Interaction-free ghost-imaging of structured objects.

This work integrates entangled photon pairs and interaction-free ghost-imaging to obtain a new imaging technique, IFGI, which can improve image signal-to-noise ratio and is sensitive to phase and polarisation changes of the photons introduced by a structured object.

Classical imaging with undetected light

We obtained the phase and intensity images of an object by detecting classical light which never interacted with it. With a double passage of a pump and a signal laser beams through a nonlinear

'Interaction-free' measurement: possibilities and limitations

The so-called 'interaction-free' measurement is a very interesting quantum effect that allows discovering the presence of an opaque object in a given spatial domain, with the probability that the

Quantum imaging and metrology with undetectedphotons: a tutorial

We present a tutorial on the phenomenon of induced coherence without induced emission, and specifically its application to imaging and metrology. It is based on a striking effect where two nonlinear

Interaction-Free Polarimetry

The combination of interaction-free measurement and the quantum Zeno effect has been shown to both increase the signal-to-noise ratio of imaging, and decrease the light intensity flux through the

Interaction-free quantum imaging

This work reports a laboratory demonstration of a new imaging scheme termed Interaction-Free Ghost Imaging, and discusses an outgrowth of this scheme used for the purpose of nonlocal quantum erasure.

"Interaction-free measurements" (IFM) originate from the latest quantum interferometric technologies. The latest research of quantum optics demonstrates, by using the complementary wavelike and

Imaging with quantum states of light

The production of pairs of entangled photons simply by focusing a laser beam onto a crystal with a nonlinear optical response was used to test quantum mechanics and to open new approaches in imaging.



Experimental and theoretical progress in interaction-free measurements

Using a hybrid of a simple interference technique and an application of the quantum Zeno effect, it is possible to optically determine the presence of an absorbing object with an arbitrarily low

Realization of an interaction‐free measurement of the presence of an object in a light beam

The gedanken experiment of Elitzur and Vaidman showing wave‐particle duality was realized as a demonstration at a scientific exposition. Presence or absence of a mirror in one arm of an

Interaction‐free quantum measurements: A paradox?

In Heisenberg’s famous discussion of the measurement of a particle’s position using a microscope, the momentum transferred to the particle by the scattered photon makes the particle’s momentum

The possibility of an “interaction-free” determination of the presence of an object was first discussed by Renninger and by Dicke,1 who examined the effect on a quantum system due to the

It is shown that one can ascertain the presence of an object in some sense without interacting with it, using single photons in a Michelson interferometer.

A novel manifestation of nonlocality of quantum mechanics is presented. It is shown that it is possible to ascertain the existence of an object in a given region of space without interacting with it.

Messungen ohne Störung des Meßobjekts

ZusammenfassungEs wird mit Hilfe von Gedankenexperimenten gezeigt, daß es entgegen verbreiteter Auffassung sehr wohl Meßvorgänge gibt, die keinerlei Rückwirkung auf das Meßobjekt ausüben. Diese
