“…Besides, we make a full quantum simulation of the entangled quantum eraser with VPPBS and we investigate complete complementarity relations in this context. It is worthwhile mentioning that, quite recently, the authors in [30] put forward a experimental setup with three-photon entangled state in which one of the photons is send into a MZI and the output beam splitter of the MZI is controlled by the quantum state of the second photon, which is entangled with a third photon. Therefore, the reduced quantum state of the second photon is undefined, which implements a undefined setting for the MZI.…”

We utilize IBM's quantum computers to perform a full quantum simulation of the optical quantum eraser (QE) utilizing a Mach-Zehnder interferometer with a variable partially-polarizing beam splitter (VPPBS) at the input. The use of the VPPBS motivates us to introduce the entangled quantum eraser, for which the path information is erased using a Bell-basis measurement. We also investigate the behavior of the wave aspect, i.e., the quantum coherence, as well as the particle character, represented by the predictability and entanglement, as delineated in complete complementarity relations (CCRs). As we show in this article, the utilization of the VPPBS uncover interesting aspects of the QE and CCRs. For instance, we can recover the full wave-behavior by the erasure procedure even when we have only partial knowledge about the path through entanglement.

Path entanglement is an essential resource for photonic quantum information processing, including in quantum computing, quantum communication, and quantum sensing. In this work, we experimentally study the generation and verification of bipartite path-entangled states using single photons produced by a nitrogen vacancy center within a nanodiamond. We perform a range of measurements to characterize the photons being generated and verify the presence of path entanglement. The experiment is performed using continuous-wave laser excitation and a novel, to our knowledge, state-generation ‘time-window’ method. This approach to path entanglement verification is different from previous work as it does not make use of a pulsed laser excitation source.
