the change in the von Neumann entropy of the system, along with the heat dissipated to the degrees of freedom of the environment. Also, we provide an experimental testbed for the protocol based on an all-optical circuit with only linear optical devices. In this case, the polarization degree of freedom encodes the information to be erased in the memory, and the path degree of freedom plays the role of the reservoir. Likewise, a quantum circuit model is provided so that the steps of the erasure can be reproduced in other quantum platforms. As such, the model provides a simple and practical architecture for the realization of tests of the Landauer principle in a quantum-mechanical scenario.
