4:58 p.m.
Dear friends,
On September 8th at 11:00 in D4.01 we'll have a guest seminar by Andrea Franzetti, who
just completed a MSc. in Physics from the University of Pavia. Andrea will be telling us
about quantifying magicness of ferminonic non-Gaussianity in the framework of Quantum
Resource Theories, title and abstract below.
Best regards,

Title: Towards Fermionic Resource Theories of Computational Advantage
Abstract: "The stabilizer formalism relies on the Gottesman-Knill theorem: every
quantum computer composed of Clifford unitaries and Pauli measurements is efficiently
simulable by a classical computer. Non-stabilizerness, or magic, is the resource
associated with the departure from this classically simulable regime, and is necessary for
universal quantum computation. In this seminar, magic will be described within the
framework of Quantum Resource Theories (QRTs), where stabilizer states are the free states
and stabilizer operations (SO) are the free operations. We address the quantification of
magic through suitable resource-measuring functions, called monotones. In particular, we
will show that the 𝛼-Stabilizer Rényi Entropies fail to completely characterize magic in
the single-shot regime. Additionaly, we will focus on non-classical simulability in
fermionic systems, showing that the fermionic Gaussian simulability paradigm is
intrinsically different from the stabilizer one. This motivates a QRT of fermionic
non-Gaussianity, where fermionic Gaussian states and operations (FGO) are free. We will
introduce a novel monotone, the entropy of non-Gaussianity, defined as the quantum
relative entropy between a fermionic state and its Gaussianization, establishing its key
properties."
