• Abstract: What is fundamentally quantum? We argue that most of the features, problems, and paradoxes -- such as the measurement problem, the Wigner's friend paradox and its proposed solutions, single particle nonlocality, and no-cloning -- allegedly attributed to quantum physics have a clear classical analogue if one is to interpret classical physics as fundamentally indeterministic. What really characterizes quantum physics boils down only to phenomena that involve $\hbar$, i.e., incompatible observables.

• Against (unitary) interpretation (of quantum mechanics): removing the metaphysical load [0.0]
  We show that "unitary quantum mechanics", which according to its followers leads to some interesting paradoxes, is an interpretation of quantum mechanics. The root of "unitary" vs. operational discrepancy is that the latter treats the measurement process as irreversible.

  We show that an arbitrary contextuality game can be compiled into an operational "test of contextuality" involving a single quantum device. Our work can be seen as using cryptography to enforce spatial separation within subsystems of a single quantum device.

  In the original thought experiment of the Quantum Cheshire Cat, the physical properties of the cat (state) can be decoupled from its quantum entities. Here, we conceive a new thought experiment that exploits quantum entanglement with weak (value) measurement.

  A new quantum postulate is suggested to restore classical locality and causality to quantum physics. This postulate supports the EPR view that quantum mechanics is incomplete, while also staying compatible to the Bohr view that nothing exists beyond the quantum.

  In opposition to classical physics, it is impossible to say that an isolated quantum system "owns" a physical property. Some properties of the system, its mass for example, belong to it in a sense close to that of classical physics.

• Ruling out real-valued standard formalism of quantum theory [19.015836913247288]
  A quantum game has been developed to distinguish standard quantum theory from its real-number analog. We experimentally implement the quantum game based on entanglement swapping with a state-of-the-art fidelity of 0.952(1). Our results disprove the real-number formulation and establish the indispensable role of complex numbers in the standard quantum theory.

• The Concept 'Indistinguishable' [0.0]
  All ordinary matter is made of electrons, protons, neutrons, and photons and they are all indistinguishable particles. The concept of indistinguishable particles has proved elusive, in part because of the interpretational difficulties that afflict quantum theory. I offer a deflationary reading of the concept "indistinguishable" that is identical to the Gibbs concept of "generic phase"

Some quantum resources, like coherence or entanglement, can also be encoded to represent the state of quantum stones. Our results establish a paradigm of inventing new games with quantum-enabled difficulties.

• Is the standard quantum mechanics a completely nondeterministic theory? [0.0]
  It is argued that although quantum theory isn't an absolutely deterministic theory, it is partially deterministic. The argument is based on the conceptual meaning of determinism and by means of some well-known phenomena in the quantum world.
