Graduate Quantum Talks

Quantum technologies have emerged as a new paradigm for computing, communication, and sensing, and represent one of the most exciting technological challenges of our time. In this seminar, we will introduce the qubit as a theoretical model, as well as the methods for controlling multiqubit coherent states through quantum gates. We will describe the key concepts behind quantum algorithms and the ideas of quantum advantage and quantum primacy. Furthermore, we will address the experimental challenge of developing a well-behaved qubit, with a focus on superconducting qubits, and provide an overview of state-of-the-art superconducting quantum processors. 

Finally, we will describe the activities carried out at the University of Milan Bicocca Cryogenic Lab, including Quantum Computing (the QISMIB initiative), and engineering, manipulating superconducting qubit systems, performing quantum-limited measurements. Encoding information into quantum states will soon allow our research group to detect the same microwave photon multiple times without absorbing it, in a process known as Quantum Non- Demolition measurement. This will have remarkable implications in Fundamental Physics such as the search for Dark Matter.

In recent years, the development of semiconductor quantum devices allowed for a substantial improvement in state of the art technology up to the point where most available optoelectronic devices rely on these properties. However, it is important to highlight that we have only scratched the surface of the immense potential unlocked by quantum physics. In this seminar, I will provide an introduction to the fascinating physical properties of quantum dots. Specifically, I will delve into the growth process of these nanostructures and show how we can effectively control their quantum properties. Furthermore, I will show the different applications of quantum dots being developed in the 4MAT Lab, which span from infrared detectors and intermediate band solar cells to non-classical photon sources.
