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…
Probes of chaos over the Clifford group and approach to Haar values
Stefano Cusumano, Gianluca Esposito, Alioscia Hamma
Chaotic behavior of quantum systems can be characterized by the adherence of the expectation values of given probes to moments of the Haar distribution. In this work, we analyze th…
