- Abstract summary: We show that coexistence of wave and particle nature emerges as a consequence of the uncertainty in the quantum controlled experimental setup.
We also show that an entanglement-assisted scheme of the same reproduces the predictions of quantum mechanics.

- Abstract: Wave-particle duality of quantum objects is one of the most striking features
of quantum physics and has been widely studied in past decades. Developments of
quantum technologies enable us to experimentally realize several quantum
phenomena. Observation of wave-particle morphing behavior in the context of the
quantum delayed-choice experiment (QDCE) is one of them. Adopting the scheme of
QDCE, we demonstrate how the coexistence of wave and particle nature emerges as
a consequence of the uncertainty in the quantum controlled experimental setup,
using a five-qubit cloud-based quantum processor. We also show that an
entanglement-assisted scheme of the same reproduces the predictions of quantum
mechanics. We put evidence that a local hidden variable theory is incompatible
with quantum mechanical predictions by comparing the variation of intensities
obtained from our experiment with hidden variable predictions.

We show that quantum systems undergo corrections to the quantum speed limit which, in turn, imply the modification of the Heisenberg limit for parameter estimation.
For some nonlocal models inspired by quantum gravity, the bounds are found to oscillate in time, an effect that could be tested in future high-precision quantum experiments.

Non-unitary dynamical processes can take place on the system, for which common quantum channel descriptions fail to describe the time evolution.
Quantum measurements are correctly treated by means of so-called quantum instruments capturing both classical outputs and post-measurement quantum states.

We find that the quantum simulator results can indeed be explained by the KZM for open-system quantum dynamics with phase-flip errors.
