It has long been assumed in physics that for information to travel between two parties in
empty space,“Alice” and “Bob,” physical particles have to travel between them. Here, using …

The classical theories of communication rely on the assumption that there has to be a flow of
particles from Bob to Alice in order for him to send a message to her. We develop a quantum …

We propose a protocol for direct quantum communication between two parties (Alice and
Bob) which is achieved by controlling the phase of the signal photon. Without imperfection …

Interaction-free measurement (IFM) is a promising technique for low-dose detection and
imaging, offering the unique advantage of probing an object with an overall reduced …

We propose quantum interaction-free measurements to determine not only whether an
object exists, but also where it is situated among possible interrogation positions. In the first …

Interaction-free measurement (IFM) is a promising technique for low-dose detection and
imaging, offering the unique advantage of probing an object without absorption of the …

Abstract We propose a Quantum Field Theory description of beams on a Mach–Zehnder
interferometer and apply the method to describe Interaction Free Measurements (IFMs) …

This paper experimentally and theoretically investigates improving interaction free
measurement (IFM) efficiency using a chain of multiple interferometers with transmissive …

A coherent picture of the wavepacket-reduction process is proposed which is formulated in
the framework of a deterministic and realist interpretation where the concepts of knowledge …

The interaction-free measurements proposed by Elitzur and Vaidman [1](EV IFM) is a
quantum mechanical method to find an object that interacts with other systems solely via its …
