- Abstract: As the preface to the special issue for the conference ``Quantum Information
and Probability: from Foundations to Engineering'' (QIP23), I wrote these notes
with recollection about V\"axj\"o conferences. These conferences covered 25
years of my life (2000-24) and played the crucial role in evolution of my own
views on the basic problems of quantum foundations. I hope to continue this
conference series as long as possible. Up to my understanding, this is the
longest conference series on quantum foundation in the history of quantum
physics. These notes contain my recollections of conversations with the world's
leading experts on quantum foundations. I think that such notes may have the
historical value. My own views on quantum foundations are specific and they
evolved essentially during 25 years. Finally, I discovered the practically
forgotten pathway in physical foundations developed by von Helmholtz, Hertz,
Boltzmann, and Schr\"odinger and known as the Bild conception. A scientific
theory is a combination of two models, observational and causal. Coupling
between these models can be tricky. A causal model can operate with hidden
quantities which can't be identified with observables. From this viewpoint,
Bell's coupling of subquantum and quantum models is very special and the
violation of the Bell inequalities doesn't close (local) ways beyond quantum
mechanics.

We introduce a quantum hardness assumption called the Hamiltonian Phase State (HPS) problem.
We show that our assumption is plausibly fully quantum; meaning, it cannot be used to construct one-way functions.
We show that our assumption and its variants allow us to efficiently construct many pseudorandom quantum primitives.

Storing quantum information requires battling quantum decoherence, which results in a loss of information over time.
To achieve error-resistant quantum memory, one would like to store the information in a quantum superposition of degenerate states engineered in such a way that local sources of noise cannot change one state into another.
We show that this platform also allows to detect and correct certain types of errors en route to the goal of true error-resistant quantum memory.

A test of quantumness is a protocol that allows a classical verifier to certify (only) that a prover is not classical.
We show that tests of quantumness that follow a certain template, which captures recent proposals such as (Kalai et al., 2022) can in fact do much more.
Namely, the same protocols can be used for certifying a qubit, a building-block that stands at the heart of applications such as certifiable randomness and classical delegation of quantum computation.
