Title: Comment on a no-go theorem for $\psi$-ontic models
Authors: Laurens Walleghem, Shashaank Khanna, Rutvij Bhavsar
Abstract summary: In a recent paper it is claimed that the whole Harrigan--Spekkens framework of ontological models is inconsistent with quantum theory. We identify some crucial mistakes in their argument to the extent that the main claim is incorrect.

Abstract: In a recent paper [Carcassi, Oldofredi and Aidala, Found Phys 54, 14 (2024)] it is claimed that the whole Harrigan--Spekkens framework of ontological models is inconsistent with quantum theory. They show this by showing that all pure quantum states in $\psi$-ontic models must be orthogonal. In this note, we identify some crucial mistakes in their argument to the extent that the main claim is incorrect.

Einstein-Podolsky-Rosen steering paradox "2=1'' for $N$ qubits [16.688291626259435]
EPR paradox highlights the absence of a local realistic explanation for quantum mechanics. We show that the contradiction holds for any $N$-qubit state as long as both the pure state requirement and the measurement requirement are satisfied.

Generalized Einstein-Podolsky-Rosen Steering Paradox [18.5699135339787]
We present a generalized EPR steering paradox, which predicts a contradictory equality $2_Q=left( 1+deltaright)_C$. We test the paradox through a two-setting steering protocol, and find that the state is steerable if some specific measurement requirements are satisfied. Our construction also enlightens the building of EPR steering inequality, which may contribute to some schemes for typical quantum teleportation and quantum key distributions.

Quantumness and quantum to classical transition in the generalized Rabi model [17.03191662568079]
We define the quantumness of a Hamiltonian by the free energy difference between its quantum and classical descriptions. We show that the Jaynes-Cummings and anti Jaynes-Cummings models exhibit greater quantumness than the Rabi model.

On the reality of the quantum state once again: A no-go theorem for $\psi$-ontic models [0.0]
We show that $psi$-ontic models, as defined by Harrigan and Spekkens (HS), cannot reproduce quantum theory. HS categorization itself is problematic as it leaves no space for models that can reproduce quantum theory.

Cold atoms meet lattice gauge theory [72.24363031615489]
We will consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is motivated by the fact that bosons are more accessible'' and easier to manipulate for experimentalists, but this substitution'' also leads to new physics and novel phenomena.

$\PT$ Symmetry and Renormalisation in Quantum Field Theory [62.997667081978825]
Quantum systems governed by non-Hermitian Hamiltonians with $PT$ symmetry are special in having real energy eigenvalues bounded below and unitary time evolution. We show how $PT$ symmetry may allow interpretations that evade ghosts and instabilities present in an interpretation of the theory within a Hermitian framework.

How Real are Quantum States in $\psi$-ontic Models? [0.0]
A series of relatively recent psi-ontology theorems have been taken to show that, provided one accepts certain assumptions, "quantum states are real" It is argued that, even if one accepts the framework and assumptions employed by such theorems, such a conclusion is not warranted.

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.
