Facilities

The Quantum Information Lab runs 4 laboratories equipped with several laser systems, more than 30 single-photon detectors (including 3 detectors in the telecom domain), and 5 counting modules. Each laboratory is equipped with advanced optical and mechanical precision instruments.

BOSON SAMPLING LABORATORY

The Boson Sampling laboratory is dedicated to advanced investigations on multiphoton interference. The laser system is composed of a 18 W duplicated Nd:Yag laser (VERDI) pumping a Ti:Sa source of femtosecond pulses (MIRA). The output field is a train of 250 fs pulses at a repetition rate of 76 MHz, achieving an output power of 2 W. The laboratory includes three photon-pair sources based on non-linear crystals that can operate simultaneously, and an advanced coupling stage for integrated devices.

QUANTUM SIMULATION LABORATORY

The Quantum simulation laboratory is dedicated to quantum simulation protocols and to the implementation of quantum information tasks at telecom wavelength. The laser system is composed of a 18 W duplicated Nd:Yag laser (VERDI) pumping a Ti:Sa source of femtosecond pulses (MIRA HP). The output field is a train of 250 fs pulses at a repetition rate of 76 MHz, achieving an output power of 3.5 W. The laboratory includes a photon-pair source for the visible range, and a photon-pair source at telecom wavelength, with two independent advanced coupling stages for integrated devices.

FOUNDATION OF QUANTUM MECHANICS LABORATORY

The Foundation of Quantum Mechanics laboratory employs orbital angular momentum of the light as a resource for quantum information and for investigations on the foundations of quantum mechanics. It is equipped with two single-photon sources and spatial light modulators. The laser system is composed of a duplicated Nd:Yag laser (VERDI) pumping a Ti:Sa source of femtosecond pulses (MIRA).
