Quantum-enhanced learning of rotations about an unknown direction
We design machines that learn how to rotate a quantum bit about an initially unknown direction, encoded in the state of a spin- j particle. We show that a machine equipped with a quantum memory of $O(\mathrm{log}j)$ qubits can outperform all machines with purely classical memory, even if the size of...
