Quantum Eigenvalue Transformations for Arbitrary Matrices

Xabier Gutiérrez, Lorenzo Laneve, Mikel Sanz

Quantum Signal Processing (QSP) and Quantum Singular Value Transformation (QSVT) provide an efficient framework for implementing polynomials of block-encoded matrices, and thus off…

Quantum statistical effects in one-particle densities: scattering and pair production

X. Gutiérrez de la Cal, M. Alkhateeb, M. Pons +2

We study space-time resolved densities of particle-hole pairs produced by an external time-dependent field acting on non-interacting non-relativistic particles. It is shown that, a…

Quantum measurements and delays in scattering by zero-range potentials

X. Gutiérrez de la Cal, M. Pons, D. Sokolovski

Eisenbud-Wigner-Smith delay and the Larmor time give different estimates for the duration of a quantum scattering event. The difference is most pronounced in the case where de-Brog…
