Researchers prove that EBI-contextuality-breaking channels strictly imply CHSH-nonlocality-breaking (not vice versa), and establish a one-to-one equivalence between EBI-CBC and triple-wise incompatibility-breaking channels for unital qubit channels.

Researchers reconstruct the quantum symmetrization algorithm to show identical particles are not discrete individuals but potential parts of a unified whole, with transtemporal identity restricted by the active role of quantum measurement.

Tim Dartois et al. simulate an EPR-Bell experiment using de Broglie-Bohm theory, showing deterministic hidden variables reproduce all QM predictions—including CHSH inequality violations—via pilot-wave particle trajectories and quantum equilibrium sampling.

Gudder derives quantum mechanics—complex Hilbert spaces, unitary operators, and Born's rule—from three real-number probabilistic axioms via a bidirectional 'dictionary', grounding QM fully in classical stochastic process theory.

Researchers derive ΔE·Δt = ℏ/√(2π) for Gaussian subcycle vacuum modes using a unit-efficiency Unruh-DeWitt detector, providing the first concrete operational basis for the virtual particle heuristic of the time-energy uncertainty principle in QFT.

Caribé et al. (U. Waterloo) used Tomita-Takesaki modular theory in 1+1D relativistic scalar fields to achieve a Bell-CHSH correlator of ~2.3, violating local realism and charting a path toward saturating Tsirelson's bound (2√2).

Simultaneous environmental measurement of conjugate observables forces decoherence in both bases, yielding a uniform ensemble with equal a priori probability — formally linking quantum decoherence to thermodynamic equilibration.

A functor from order-unit spaces to probabilistic test-space models formally unifies the convex-operational and test-space frameworks for quantum theory—no generalized test spaces required—while clarifying the structure of unsharp observables.

A new elementary proof shows that N-particle wave functions must be totally symmetric or antisymmetric under particle exchange, derived from Schrödinger equation constraints—extended to systems in electromagnetic fields.

Lu argues Hilbert spaces remain valid in QM: infinite expectation values aren't unphysical, and replacing them with Schwartz spaces would exclude meaningful Hamiltonians like Coulomb potentials, causing more problems than it solves.

All of QM—complex Hilbert spaces, Born rule, unitary dynamics—derived from one axiom: equality has finite resolution. A capacity deficit (Ω(N²) bits required vs log₂N available) forces indeterminism and uniquely selects p_k=|c_k|².

Researchers construct 12 Hardy's paradoxes for the Yu-Oh set (minimal SIC system, 13 vectors), identifying all logically contextual pure states and proving no mixed states qualify, each paradox achieving success probability SP=11.1%.

Seoane et al. show cavity QED can be fully modeled using Bohmian electron trajectories + quantized EM field modes, without ontic photons. Photon partition noise emerges from matter detector particle-nature, not intrinsic photon corpuscularity.
#BohmianMechanics #QuantumFoundations #Research
Seoane et al. demonstrate via Bohmian mechanics that position post-selected weak values can be realistically interpreted as particle properties without inconsistency, formally refuting Aredes & Saldanha's logically fallacious equivalence claim.

Researchers identify mild assumptions on local hidden variable theories enabling Bell inequality tests at colliders using μ+μ− and τ+τ− pairs, deriving continuous-variable CHSH inequalities with tighter bounds than standard binary versions.

Goyal constructs a quantum property model from Feynman's rules reconstruction, applying Aristotle's actuality/potentiality to resolve Zeno's paradox and explain entanglement and double-slit diffraction via extended simples and complexes.

Researchers show the partial trace emerges naturally from requiring consistency between the Born rule and classical probability marginalization—grounding reduced density operators in probabilistic foundations rather than ad hoc algebra.

Using unconstrained weak measurements on IBM & IonQ quantum computers, researchers violated objective realism at 10 standard deviations—surpassing prior constrained tests and validating two-qubit gate quality on publicly accessible hardware.

If you could run ONE simulation of the universe—no limits, no assumptions—what would it be?
Consciousness? Time? Pre-spacetime reality? Are observers inevitable or contingent?

We got lost in the measurement-problem literature—so we drew a map.
New review in Philos Mag: #decoherence + today’s main approaches, incl. many worlds, objective collapse, hidden variables & epistemic views—plus measurement in QFT.

@seanmcarroll.bsky.social >> Sean, regarding the 'measurement problem': if the wavefunction collapse is just a local scalar stress transient in the E8 lattice (changing the local refractive index), does that preserve unitarity? #QuantumFoundations
