Prerequisites

Students are expected to have basic knwledge of the structure of matter and condensed matter physics as aquired in undergraduate courses, The present course if recommended for PhD students.

Programme

Cold-atom-based quantum technologies

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 (examples of analog quantum simulators).

Nanoabrication for QT

State-of-the-art fabrication techniques for devices based on semiconductor and superconductors. Introduction to cleanroom, lithography, material growth, deposition and etching (wet and dry).

Superconductor-based QTs

Introduction to the Josephson effect and superconducting circuits. Architectures of the three basic superconducting qubits (phase, charge and flux qubit). Coupling superconducting qubits and more advanced qubits (for example used in Google's Sycamore quantum computer).

Thermal transport in superconducting nanostructures, thermometry and cooling techniques. Phase-dependent heat transport in superconducting quantum circuits: the basis of coherent caloritronics. Quantum sensing with superconducting circuits.

Semiconductor-based QTs

Semiconductor-based qubits (Hall systems, single-vacancies). Qubits based on semiconductor/superconductor hybrid structures (gatemons). Single-spin systems in diamonds nitrogen vacancies. Introduction to quantum cryptography. Single-photon sources and detectors based on semiconducting systems.

Educational aims

Students will be introduction to the main architectures of interest for quantum science and technology based on cold atoms, semiconductors and superconductors together with the necessary nanofabrication technoques. The course will present some of the  to current research activities in the field of quantum science and technology.
