We report a delayed "choice" quantum eraser experiment of the type proposed by Scully and Druhl (where the "choice" is made randomly by a photon at a beam splitter). The experimental results demonstrate the possibility of delayed determination of particlelike or wavelike behavior via quantum entanglement. The which-path or both-path information of a quantum can be marked or erased by its entangled twin even after the registration of the quantum.

Delayed-choice quantum eraser for the undergraduate laboratory
In a delayed-choice quantum eraser, interference fringes are obtained by erasing which-way information after the interfering particle has already been irreversibly detected. Following an introductory
The ‘Delayed Choice Quantum Eraser’ Neither Erases Nor Delays
It is demonstrated that ‘quantum eraser’ (QE) experiments do not erase any information. Nor do they demonstrate ‘temporal nonlocality’ in their ‘delayed choice’ form, beyond standard EPR
The Vienna Delayed-Choice Quantum Eraser Leaves No Choice
A realizable delayed-choice quantum eraser, using a modified Mach-Zehnder (MZ) interferometer and polarization entangled photons, is theoretically analyzed here. The signal photon goes through a
How to Erase Quantum Monogamy?
The phenomenon of quantum erasure exposed a remarkable ambiguity in the interpretation of quantum entanglement. On the one hand, the data is compatible with the possibility of arrow-of-time
Observations of delayed-choice quantum eraser using a continuous wave laser
Quantum superposition is the heart of quantum mechanics, satisfying complementarity theory between the particle and wave natures of a physical entity such as a photon or atom. Delayed choice of
Quantum disentanglement eraser: A cavity QED implementation
A possible experimental scheme of the Garisto-Hardy disentanglement eraser based on a cavity QED system is presented. This scheme can be used for a delayed choice quantum eraser. It also allows us to
Quantum entanglement, Wheeler’s delayed choice experiment and its explanation on the basis of quantization of fields
The result of Wheeler's delayed choice experiment is a natural consequence of the entanglement of moving photons and particles (atoms, molecules) of the slit through which they move. The inclusion of
Experimental demonstration of delayed-choice decoherence suppression.
TLDR
The delayed-choice decoherence suppression protocol is introduced, in which the decision to suppressDecoherence on an entangled two-qubit state is delayed until after the decoherent and even after the detection of a qubit.
Another Quantum Eraser Experiment with Two-photon States of Light
The quantum eraser experiment was revisited, using entangled photons of visible light in a Hong-Ou-Handel type interferometer with a magnitude two orders higher than before in count rates. We
Taming the Delayed Choice Quantum Eraser
I discuss the delayed choice quantum eraser experiment by drawing an analogy to a Bell-type measurement and giving a straightforward account in standard quantum mechanics. The delayed choice quantum
