Efficient qubit phase estimation using adaptive measurements
Marco A. Rodríguez-García, Isaac Pérez Castillo, P. Barberis-Blostein
Estimating correctly the quantum phase of a physical system is a central problem in quantum parameter estimation theory due to its wide range of applications from quantum metrology…
Quantum quench in a driven Ising chain
Neil J. Robinson, Isaac Pérez Castillo, Edgar Guzmán-González
We consider the Ising chain driven by oscillatory transverse magnetic fields. For certain parameter regimes, we reveal a hidden integrable structure in the problem, which allows ac…
Analytic approach for the number statistics of non-Hermitian random matrices
Antonio Tonatiúh Ramos Sánchez, Edgar Guzmán-González, Isaac Pérez Castillo +1
We introduce a powerful analytic method to study the statistics of the number of eigenvalues inside any contour for infinitely large…
The exact two-spinon longitudinal dynamical structure factor of the anisotropic XXZ model
Isaac Pérez Castillo
Inelastic neutron scattering experiments are commonly used to unveil how excitations on Heisenberg spin models play a role in dynamical correlations functions. For a certain class…
