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 qubit with solid-state, atomic and optical systems: superconducting circuits, nuclear end electron magnetic resonances, ions, neutral atoms and photonic circuits;

- unitary operations on the single qubit and logical gates with two qubits;

- initialization and detection.

· 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.
