99247 - QUANTUM SCIENCES AND TECHNOLOGIES

Learning outcomes

At the end of the course the students will acquire the basic notions about the main physical systems and the experimental methods used to create the quantum technologies at the heart of the second quantum revolution. The students will become familiar with physical systems to create qubits and platforms for quantum computing, sensing, simulations and communication, spanning from optical to atomic and solid states systems. In addition, the students will learn about the main experimental techniques to manipulate qubits, engineer quantum superpositions and make use of entanglement.

Course contents

· Quantum Computing and Simulations:

- physical realizations of the qbit: solid-state (superconducting circuits, q-dots, topological materials, molecular magnets), atomic (ion traps, chains of Rydberg atoms, optical lattices) and optical;

- manipulation techniques for unitary operations on the single qbit and for logical gates with two qbits (magnetic resonances, laser,...);

- principles of q. simulators as specialized q. computer;

- q. simulators with atomic and photonic systems: ion traps, arrays of neutral atoms, optical lattices, photonic circuits.

· Quantum Sensing:

- underlying principles of sensing elements: resonance and interference;

- sensing by resonance: optical clocks, nitrogen-vacancy in diamond;

- sensing by interference: squid, atomic interferometers;

- entanglement-enhanced sensitivity.
