In Robert McEachern's view, the "measurement problem" in quantum theory - the
difficulty in reconciling the continuous evolution of a quantum system with the
discrete outcomes of measurements - is an artifact of misinterpreting the theory's
purpose.
McEachern's Core Idea
Quantum theory describes the statistical probabilities of detecting energy
associated with "matched filtering" processes. This approach focuses on the
success or failure of "detection tests," rather than describing the behavior of
particles.
Many seemingly paradoxical phenomena in quantum mechanics, such as non-
locality, entanglement, and the uncertainty principle, may arise from
misinterpretations of the mathematical descriptions used to represent them,
rather than reflecting inherent strangeness in reality.
Real-world detectors are prone to "false alarms" (bit-errors), a factor often ignored
in arguments like Bell's theorem.
Implications of This Perspective
The foundations of quantum physics may require re-evaluation. If quantum theory
primarily describes energy detection and not the underlying reality, the focus
shifts from interpretations of the wavefunction collapse to a deeper
understanding of how detectors interact with quantum systems.
"Weird" quantum phenomena may be viewed differently. Entanglement, non-
locality, and uncertainty might be seen as properties of the detection process
rather than intrinsic qualities of reality.
Detector characteristics become important. Factors like detector efficiency and
the prevalence of false positives (or false alarms) become crucial in
understanding and interpreting experimental results.
There's potential for unifying quantum mechanics with classical physics. By re-
framing quantum mechanics as a theory of energy detection, it might be possible
to bridge the gap between the quantum and classical worlds, potentially through a
new understanding of information and signal processing.
McEachern's interpretation proposes a profound shift in how quantum theory is
understood. Instead of viewing it as a description of an inherently strange reality, it
should be considered as a tool for predicting the outcomes of energy detection,
taking into account the limitations and nuances of real-world detectors.
