Prerequisiti

Graduate-level quantum mechanics and fundamentals of atomic physics and band theory in crystals are required. Introductory lectures on the physics of superconductors and hybrid superconductor-normal systems are part of the course program.

Programma

Cold-atom-based QTs

Quantum technologies with laser-cooled atoms: an introduction to the physical platform, experimental tools and methods. Cold atoms for sensing and metrology: atomic clocks and atom interferometers. Cold atoms for quantum simulation: engineering quantum models and synthetic materials with atoms and light. Cold atoms for quantum computing.

 

Photon-based QTs

Overview on the different technologies needed to generate photonics quantum states (in either single photon or multi-photon configurations), to manipulate, and to detect quantum states of light across a broad range of frequencies, using bulk and integrated platforms. Overview on the different applications of photonics platform: quantum sensing, quantum communication, quantum simulation and quantum computing

 

Semiconductor-based QTs

Heterostructures (HSs): electronic states, carrier statistics, quantum transport and optical properties of superlattices, quantum wells and wires. Nanofabrication, quantum devices. 2D electron gas in HSs and 2D materials. Twistronics. Integer and fractional quantum Hall effects. Andreev reflection and proximity effect in hybrid semiconductor/superconductor systems. Semiconductor and hybrid-system architectures for quantum computation. 

 

Superconductor-based QTs

Introduction to Josephson effect and superconducting circuits. Basic architectures of superconductor qubits: phase, charge and flux qubit. Coupling superconducting qubits in functional QT systems. Thermal transport in superconducting nanostructures, thermometry and cooling techniques. Phase-dependent effects. Quantum sensing with superconducting circuits.

Obiettivi formativi

The main technological platforms of interest for quantum technology are presented. The course is designed to give an up-to-date presentation of the available methods for the experimental realization of the configurations of interest for QT-based functional systems and devices.
