The Ontic Necessity of the Quantum Wavefunction: Why Epistemic Views Struggle with the Uncertainty Principle [0.0]
The ontological status of the quantum wavefunction remains one of the most debated questions in quantum theory.<n>Treating the wavefunction as ontic allows a consistent and natural derivation of quantum uncertainty from the mathematical structure of Hilbert space.

Probing the nonclassical dynamics of a quantum particle in a gravitational field [0.0]
In quantum mechanics, the time evolution of particles is given by the Schr"odinger equation. We propose to measure the effects of an asymmetric mass configuration on a quantum particle in an interferometer.

Quantifying non-Hermiticity using single- and many-particle quantum properties [14.37149160708975]
The non-Hermitian paradigm of quantum systems displays salient features drastically different from Hermitian counterparts. We propose a formalism that quantifies the (dis-)similarity of these right and left ensembles, for single- as well as many-particle quantum properties. Our findings can be instrumental in unveiling new exotic quantum phases of non-Hermitian quantum many-body systems.

Antiparticles in non-relativistic quantum mechanics [55.2480439325792]
Non-relativistic quantum mechanics was originally formulated to describe particles. We show how the concept of antiparticles can and should be introduced in the non-relativistic case without appealing to quantum field theory.

Universality in Quantum Measurements [0.0]
We briefly review a number of major features of the approach to quantum measurement theory based on environment-induced decoherence of the measuring apparatus. We summarize our observations in the form of a couple of general principles that, unlike the wave function collapse hypothesis, emerge as ones consistent with the unitary Schr"odinger evolution of wave functions.

On free fall of fermions and antifermions [0.0]
We propose a model describing spin-half quantum particles in curved spacetime. We find that spin precesses in a normal Fermi frame, even in the absence of torsion. We also find that (elementary) fermions and antifermions are indistinguishable in gravity.

Spin operator, Bell nonlocality and Tsirelson bound in quantum-gravity induced minimal-length quantum mechanics [0.0]
We show that the spin operator acquires a momentum-dependent contribution in quantum mechanics equipped with a minimal length. Among other consequences, this modification induces a form of quantum nonlocality stronger than the one arising in ordinary quantum mechanics.

Experimental demonstration of optimal unambiguous two-out-of-four quantum state elimination [52.77024349608834]
A core principle of quantum theory is that non-orthogonal quantum states cannot be perfectly distinguished with single-shot measurements. Here we implement a quantum state elimination measurement which unambiguously rules out two of four pure, non-orthogonal quantum states.

Correspondence Between the Energy Equipartition Theorem in Classical Mechanics and its Phase-Space Formulation in Quantum Mechanics [62.997667081978825]
In quantum mechanics, the energy per degree of freedom is not equally distributed. We show that in the high-temperature regime, the classical result is recovered.

On the Interpretation of Quantum Indistinguishability : a No-Go Theorem [0.0]
Physicists are yet to reach a consensus on the interpretation of a quantum wavefunction. We show that quantum mechanical prediction of maximal violation of Mermin inequality is incompatible with all ontological interpretations for quantum theory.

We build an axiomatization for quantum realism -- a notion of realism compatible with quantum theory. We explicitly construct some classes of entropic quantifiers that are shown to satisfy almost all of the proposed axioms.

A Simple Proof of Locality in Quantum Mechanics [0.0]
We show that quantum mechanics respects locality since there is no instantaneous propagation of real physical effects. This is reminiscent of satisfying the locality condition in relativistic quantum field theories.

Quantum indistinguishability through exchangeable desirable gambles [69.62715388742298]
Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

Experimental quantum phase discrimination enhanced by controllable indistinguishability-based coherence [13.745478068219699]
Coherence emerges in a fundamentally different way for nonidentical and identical particles. We experimentally demonstrate this additional contribution to quantum coherence. Our experiment proves that independent indistinguishable particles can supply a controllable resource of coherence.

The Time-Evolution of States in Quantum Mechanics [77.34726150561087]
It is argued that the Schr"odinger equation does not yield a correct description of the quantum-mechanical time evolution of states of isolated (open) systems featuring events. A precise general law for the time evolution of states replacing the Schr"odinger equation is formulated within the so-called ETH-Approach to Quantum Mechanics.

Quantum Mechanical description of Bell's experiment assumes Locality [91.3755431537592]
Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality. This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment. It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
