Entanglement and the measurement problem
Art Hobson
The entangled "measurement state" (MS), predicted by von Neumann to arise during quantum measurement, seems to display paradoxical properties such as multiple macroscopic outcomes.…
The entangled measurement state is not a paradoxical superposition of the detector
Art Hobson
The entangled state that results when a detector measures a superposed quantum system has spawned decades of concern about the problem of definite outcomes or "Schrodinger's cat."…
Solving the measurement problem within standard quantum theory
Art Hobson
A misunderstanding of entangled states has spawned decades of concern about quantum measurements and a plethora of quantum interpretations. The "measurement state" or "Schrodinger'…
Entanglement, decoherence, and the measurement problem
Art Hobson
The entangled Schrodinger cat state obtained immediately upon measurement of a superposed two-state quantum system is often considered paradoxical because it appears to predict two…
Product states, entanglement, and measurement
Art Hobson
A product state of a composite quantum system AB is customarily interpreted physically to mean subsystem A has property A1 and subsystem B has property B1. But this interpretation…
Realist Analysis of Six Controversial Quantum Issues
Art Hobson
This paper presents a philosophically realistic analysis of quantization, field-particle duality, superposition, entanglement, nonlocality, and measurement. These are logically rel…
Quantum realism is consistent with quantum facts
Art Hobson
Despite the unparalleled accuracy of quantum-theoretical predictions across an enormous range of phenomena, the theory's foundations are still in doubt. The theory deviates radical…
Review and suggested resolution of the problem of Schrodinger's cat
Art Hobson
This paper reviews and suggests a resolution of the problem of definite outcomes of measurement. This problem, also known as "Schrodinger's cat," has long posed an apparent paradox…
Solution of the problem of definite outcomes of quantum measurements
Art Hobson
Theory and experiment both demonstrate that an entangled quantum state of two subsystems is neither a superposition of states of its subsystems nor a superposition of composite sta…
Resolving Schrodinger's cat
Art Hobson
Schrodinger's famous cat has long been misunderstood. According to quantum theory and experiments with entangled systems, an entangled state such as the Schrodinger's cat state is…
Resolving the problem of definite outcomes of measurements
Art Hobson
The entangled "Schrodinger's cat state" of a quantum and its measurement apparatus is not a paradoxical superposition of states but is instead a non-paradoxical superposition of no…
Resolving the problem of definite outcomes of measurements
Art Hobson
The heart of the measurement puzzle, namely the problem of definite outcomes, remains unresolved. This paper shows that Josef Jauch's 1968 reduced density operator approach is the…
Why decoherence solves the measurement problem
Art Hobson
Although the solution, within standard quantum physics, of the problem of outcomes has been published several times, many authors continue to treat measurement as an unsolved funda…
Two-photon interferometry illuminates quantum measurements
Art Hobson
The quantum measurement problem still finds no consensus. Nonlocal interferometry provides an unprecedented experimental probe by entangling two photons in the "measurement state"…
Re-assessment of the state of Schroedinger's cat, final version
Art Hobson
The quantum state of Schroedinger's cat is usually incorrectly described as a superposition of "dead" and "alive," despite an argument by Rinner and Werner that, locally, the cat s…
There are no particles, there are only fields
Art Hobson
Quantum foundations are still unsettled, with mixed effects on science and society. By now it should be possible to obtain consensus on at least one issue: Are the fundamental cons…
