ESE Spring Seminar – “From Exact Laws to Design Principles of Quantum Information Machines”

March 31, 2022 at 11:00 AM - 12:00 PM

Many-body quantum systems are the most powerful computers allowed by Nature.

How do they work? Can we control them? Are they useful?

In this talk, I discuss how recent results in quantum information theory translate into quantum engineering solutions. I introduce a geometric information measure that rigorously evaluates the difference between two complex configurations of arbitrarily large quantum systems, e.g., thousands of interacting atoms. The result is instrumental in finding the maximum conversion rate of physical resources, such as energy and time, into quantum computational power. A simple but universally valid inequality, formally similar to the Heisenberg uncertainty relations, bounds the size of a program that creates a target quantum state by its experimental cost.

Finally, I outline strategies to tackle critical problems related to information storage in quantum networks, diagnostics of quantum devices, and quantum sensing. New ways to identify, quantify, and harness distinctive traits of quantum particles, e.g., entanglement, will accelerate the transition of quantum technologies from textbooks to reality

Davide Girolami

R. Levi Montalcini Assistant Professor, Politecnico di Torino

Davide Girolami develops theoretical ideas and methods to understand elusive properties of quantum systems, such as quantum coherence and quantum correlations, which promise to be the key resources for quantum technologies. He is currently R. Levi Montalcini Assistant Professor at Politecnico di Torino. Previously, he was J. R. Oppenheimer Distinguished Fellow and Director’s Fellow at Los Alamos National Laboratory, EPSRC Fellow/J. Martin Fellow and Junior Research Fellow of Wolfson College at University of Oxford, and a Postdoctoral Fellow at National University of Singapore. He holds a PhD from University of Nottingham.
