Quantum Cafe: Antonio Mezzacapo

Quantum Café is CCQ’s ongoing seminar series: open to all bona fide members of the greater NYC scientific community and held every second week, Quantum Café presents a series of informal, highly interactive talks, typically by external speakers, which present the most interesting recent developments and open questions in our field.

Title: Fermi Systems and Quantum Computing

Abstract: Solving correlated Fermi systems is a problem of ubiquitous importance in the fields of chemistry, materials science and fundamental interactions. Quantum computers can help addressing this type of challenges, provided that descriptions of Fermi systems are loaded onto a set of qubits. In this talk I will review methods to represent Fermi quantum states and interactions onto a set of qubits, how to optimize mapping procedures, and how these methods are used to perform computations on quantum hardware. I will then introduce connections between such mappings and stabilizer codes, showing that adequate encodings can account for the correction of single-qubit errors. Finally, I will show how the tools presented can have an impact on classical numerical methods.
