Many-body dynamical localization emerges in the Fock space of a driven interacting bosonic system, suppressing transport and producing a crossover to Poisson spectral statistics.
A protocol using emergent Hamiltonians enables storage of Bell-product and GHZ entangled states by making them exact eigenstates of a local Hamiltonian.
A squeezed-vacuum interferometer with nonlinear phase estimation achieves Heisenberg scaling in the lossless limit, sub-SQL sensitivity under noise, and the first experimental quantum-optimal Bayesian signal estimation in a balanced interferometer.
