"device that has the same behavior as a memristor, while acting on quantum states and being able to encode and transmit quantum information... single photons propagate along waveguides laser-written on a glass substrate and are guided on a superposition of several paths... Besides demonstrating the quantum memristor, the researchers have provided simulations showing that optical networks with the quantum memristor can be used to learn on both classical and quantum tasks"
