- Abstract: Precise control of quantum systems with a moderate number of degrees of
freedom, being of interest for application in quantum technologies, becomes
experimentally feasible. Various types of quantum scenarios and protocols are
being widely discussed in scientific literature. We propose, analyze, and
optimize a protocol which allows fast simulation of properties of unknown
quantum states relying on minimum relevant information. Our protocol, having
common features with quantum identification and shortcuts to adiabaticity,
permits avoiding orthogonality catastrophe, where transitions between
physically very similar systems are characterized by zero or a very low
fidelity.

The No-Free-Lunch (NFL) theorem quantifies problem- and data-independent generalization errors regardless of the optimization process.
We categorize a diverse array of quantum learning algorithms into three learning protocols designed for learning quantum dynamics under a specified observable.
Our derived NFL theorems demonstrate quadratic reductions in sample complexity across CLC-LPs, ReQu-LPs, and Qu-LPs.
We attribute this performance discrepancy to the unique capacity of quantum-related learning protocols to indirectly utilize information concerning the global phases of non-orthogonal quantum states.

We develop a protocol for constructing shortcuts to adiabaticity through the multi-state Landau-Zener approach and a stricter adiabatic condition.
Importantly, our protocol only requires a few pieces of information about the energy spectrum and adjusts the evolutionary rate of the system.
Our findings can be realized using current technology and could potentially be extended to many-body systems, dissipation cases, or Floquet processes.
