Quantum simulation

IBM Q Experience as a versatile experimental testbed for simulating open quantum systems

The advent of Noisy Intermediate-Scale Quantum (NISQ) technology is changing rapidly the landscape and modality of research in quantum physics. NISQ devices, such as the IBM Q Experience, have very recently proven their capability as experimental …

Quantum Simulation of Non-Markovian Qubit Dynamics by an All-Optical Setup

We address the experimental implementation of a quantum simulator based on an optical setup. Our device can simulate the dynamical evolution of a qubit undergoing a dephasing process. In particular, we focus on the dynamics arising from the …

Non-Markovianity by undersampling in quantum optical simulators

All-optical quantum simulator of qubit noisy channels

We suggest and demonstrate an all-optical quantum simulator for single-qubit noisy channels originating from the interaction with a fluctuating field. The simulator employs the polarization degree of freedom of a single photon and exploits its …
