QTris: a pedagogical board game to teach Quantum Mechanics
Alessandro Amabile, Maria Bondani, Immacolata De Simone +3
In this paper we introduce the new version of QTris, a board game designed to teach and learn Quantum Mechanics within the framework of Quantum Information and Computation. The key…
Quantum Chinese Remainder Clock
Ivri Nagar, Alioscia Hamma, Mikel Palmero +3
The Chinese remainder theorem is used in metrology for extending the range of quantum clocks/radar/interferometry, where the phase of a signal is known relative to a set of oscilla…
Non-Local Magic Resources for Fermionic Gaussian States
Daniele Iannotti, Beatrice Magni, Riccardo Cioli +2
Entanglement and magic are fundamental resources that capture the complexity of quantum many-body systems. Non-local magic isolates the irreducible nonstabilizerness intrinsically…
Stabilizer entropy is trustworthy for mixed states
Gianluca Esposito, Michele Viscardi, Alioscia Hamma
Quantifying non-stabilizerness in mixed states is provably intractable, as any strict monotone requires superexponential time. We propose a linear Stabilizer Entropy that acts as a…
Experimental demonstration of non-local magic in a superconducting quantum processor
Halima Giovanna Ahmad, Gianluca Esposito, Viviana Stasino +9
Non-local magic is the non-stabilizerness that no local unitary operation can erase. It captures the joint action of entanglement and magic underlying quantum advantage, and it has…
Non-stabilizerness and violations of CHSH inequalities
Stefano Cusumano, Lorenzo Campos Venuti, Simone Cepollaro +7
We study quantitatively the interplay between entanglement and non-stabilizer resources in violating the CHSH inequalities. We show that, while non-stabilizer resources are necessa…
