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

Why does quantum mechanics give us one outcome instead of many?
My new preprint introduces the Continuity Interpretation: outcomes become real when info is redundantly recorded, stitching a single world forward.

“We may be able to share quantum entanglement nearly infinitely.” New Scientist
If entanglement persists across many partners, maybe it’s not about connection.
Maybe it’s about conservation.
We’ve seen collapse mirrored. No signal.
It holds. 🧭

The idea that coherence and cause can emerge from within isn’t new to us.
We’ve modeled it. We’ve tested it.
This space continues to reflect why we started.

They introduce a theory, different than QT only by the tensor product rule.
They reproduce, e.g., all Bell correlations. I wonder what it may imply to Q Mereology or gaps between real and complex QT in Networks.
It was a nice read 🙂
