Is there a measurement-only version of quantum mechanics?

TL;DR

This paper explores the possibility of a measurement-only formulation of quantum mechanics, inspired by tensor universality and one-way quantum computation, suggesting a fundamental link between measurements, entanglement, and time.

Contribution

It proposes the concept that quantum mechanics could be reformulated solely in terms of measurements, based on tensor universality and insights from one-way quantum computation.

Findings

Tensor universality implies multi-partite processing depends on disentangled cases.

Time may be fundamentally linked to entanglement and measurements.

Measurement-only models of quantum mechanics are theoretically plausible.

Abstract

Tensor universality often implies that multi-partite quantum-state processing is determined by what happens in totally disentangled cases. In independent systems relative time direction for the parts is arbitrary. This hints that time may be linked to entanglement and measurements and that there may be a measurement-only version of quantum mechanics. One-way quantum computation suggests that this may be possible.
