- Abstract: Reservoir engineering is a powerful technique to autonomously stabilize a
quantum state. Traditional schemes involving multi-body states typically
function for discrete entangled states. In this work, we enhance the
stabilization capability to a continuous manifold of states with programmable
stabilized state selection using multiple continuous tuning parameters. We
experimentally achieve $84.6\%$ and $82.5\%$ stabilization fidelity for the odd
and even-parity Bell states as two special points in the manifold. We also
perform fast dissipative switching between these opposite parity states within
$1.8\mu s$ and $0.9\mu s$ by sequentially applying different stabilization
drives. Our result is a precursor for new reservoir engineering-based error
correction schemes.

We introduce a new stability measure called on-average model stability, for which we develop novel bounds controlled by the risks of SGD iterates.
This yields generalization bounds depending on the behavior of the best model, and leads to the first-ever-known fast bounds in the low-noise setting.
To our best knowledge, this gives the firstever-known stability and generalization for SGD with even non-differentiable loss functions.
