Interaction-free measurement is a type of quantum measurement that detects the state of an object without an interaction occurring between the object and the measuring device. A scheme for interaction-free measurement was proposed by Elitzur and Vaidman called Elitzur-Vaidman bomb tester where they used a Mach-Zehnder interferometer to detect whether a bomb is alive or dead. In 1992, Lucien Hardy proposed an experiment that a particle and its antiparticle may interact without annihilating each other which called Hardy’s paradox. In this work, we demonstrate the above experiments using quantum computing, which are realized in IBM quantum computers.
