Quantum circuits to measure scalar spin chirality
L. I. Reascos, Bruno Murta, E. F. Galvão +1
The scalar spin chirality is a three-body physical observable that plays an outstanding role both in classical magnetism, characterizing non-coplanar spin textures, and in quantum…
Non-stabilizerness and entanglement from cat-state injection
Filipa C. R. Peres, Rafael Wagner, Ernesto F. Galvão
Recently, cat states have been used to heuristically improve the runtime of a classical simulator of quantum circuits based on the diagrammatic ZX-calculus. Here we investigate the…
A simple proof that anomalous weak values require coherence
Rafael Wagner, Ernesto F. Galvão
The quantum mechanical weak value of an observable is a measurable quantity associated with an observabl…
Quantum circuits for measuring weak values, Kirkwood--Dirac quasiprobability distributions, and state spectra
Rafael Wagner, Zohar Schwartzman-Nowik, Ismael L. Paiva +5
Weak values and Kirkwood--Dirac (KD) quasiprobability distributions have been independently associated with both foundational issues in quantum theory and advantages in quantum met…
