Quantifying Entangling Power of Controlled Unitary Gates

Applying controlled unitary gates to generate entanglement between qubits is a routine task in both quantum communication and computation. The existing tools for predicting how much entanglement a given gate can generate require either simulation of the entangling circuit or averaging over a distribution of inputs for...

Quantum computer-based simulation of Stark many-body localization in a 1D Fermi-Hubbard model

This work studies Stark MBL in a 12-qubit correlated fermionic system described by the one-dimensional Fermi-Hubbard model using Hamiltonian simulation on an IBM superconducting qubit quantum computer and exhibits a crossover from thermalizing dynamics of the system at a weak tilt of the field to a strongly localized b...
