Resumen
We present an experimental optical implementation of a parallel-in-time discrete model of quantum evolution,
based on the entanglement between the quantum system and a finite-dimensional quantum clock. The setup is
based on a programmable spatial light modulator which entangles the polarization and transverse spatial degrees
of freedom of a single photon. It enables the simulation of a qubit history state containing the whole evolution
of the system, capturing its main features in a simple and configurable scheme. We experimentally determine
the associated system-time entanglement, which is a measure of distinguishable quantum evolution, and also the
time average of observables, which in the present realization can be obtained through one single measurement.
