Random Delayed-Choice Quantum Eraser via Two-Photon Imaging
We report on a delayed-choice quantum eraser experiment based on a two-photon imaging scheme using entangled photon pairs. After the detection of a photon which passed through a double-slit, a random delayed choice is made to erase or not erase the which-path information by the measurement of its distant entangled twin; the particle-like and wave-like behavior of the photon are then recorded si...
متن کاملA Delayed Choice Quantum Eraser
Complementarity, perhaps the most basic principle of quantum mechanics, distinguishes the world of quantum phenomena from the realm of classical physics. Quantum mechanically, one can never expect to measure both precise position and momentum of a quantum at the same time. It is prohibited. We say that the quantum observables “position” and “momentum” are “complementary” because the precise kno...
متن کاملAn Operational Analysis of Quantum Eraser and Delayed Choice
In the present paper we expand upon ideas published some time ago in connection with which path detectors based on the micromaser . Frequently questions arise concerning the time ordering of detection and eraser events. We here show , by a detailed and careful analysis of a quantum eraser experimental setup, that the experimenter can choose to ascertain particle-like which path information or w...
متن کاملA delayed choice quantum eraser explained by the transactional interpretation of quantum mechanics
This paper explains the delayed choice quantum eraser of Kim et al. [1] in terms of the transactional interpretation of quantum mechanics by John Cramer [2, 3]. It is kept deliberately mathematically simple to help explain the transactional technique. The emphasis is on a clear understanding of how the instantaneous “collapse” of the wave function due to a measurement at a specific time and pla...
متن کاملA quantum delayed-choice experiment.
Quantum systems exhibit particle- or wavelike behavior depending on the experimental apparatus they are confronted by. This wave-particle duality is at the heart of quantum mechanics. Its paradoxical nature is best captured in the delayed-choice thought experiment, in which a photon is forced to choose a behavior before the observer decides what to measure. Here, we report on a quantum delayed-...
