The projection postulate, which prescribes "collapse of the state vector" upon measurement, is not an essential part of quantum mechanics. Rather it is only an optional discarding of certain branches of the state vector that are expected to be irrelevant for the purpose at hand. However, its use is hazardous, and there are examples of repeated measurements for which the conventional application of the projection postulate leads to incorrect results.

“…A type of wave-function-collapse interpretation was offered as a possible explanation for the reported anomalous effect in the Radin DS-experiment (see Radin et al, 2012), whereby the particular interpretation assigns a special role to human consciousness, hence the term also of “quantum consciousness,” as part of the quantum-measurement process (e.g., von Neumann, 1932). More than 40 years ago, Hall et al (1977) tested in the laboratory the proposal that “the reduction of the wave packet is a physical event which occurs only when there is an interaction between the physical measuring apparatus and the psyche of some observers”; however, these experiments found no evidence for any influence of the consciousness of a test subject on the targeted quantum-based process (Hall et al, 1977).…”

Prior work by Radin et al. (2012 , 2016) reported the astonishing claim that an anomalous effect on double-slit (DS) light-interference intensity had been measured as a function of quantum-based observer consciousness. Given the radical implications, could there exist an alternative explanation, other than an anomalous consciousness effect, such as artifacts including systematic methodological error (SME)? To address this question, a conceptual replication study involving 10,000 test trials was commissioned to be performed blindly by the same investigator who had reported the original results. The commissioned study performed confirmatory and strictly predictive tests with the advanced meta-experimental protocol (AMP), including with systematic negative controls and the concept of the sham-experiment, i.e., counterfactual meta-experimentation. Whereas the replication study was unable to confirm the original results, the AMP was able to identify an unacceptably low true-negative detection rate with the sham-experiment in the absence of test subjects. The false-positive detection rate reached 50%, whereby the false-positive effect, which would be indistinguishable from the predicted true-positive effect, was significant at p = 0.021 ( σ = −2.02; N = 1,250 test trials). The false-positive effect size was about 0.01%, which is within an-order-of-magnitude of the claimed consciousness effect (0.001%; Radin et al., 2016 ). The false-positive effect, which indicates the presence of significant SME in the Radin DS-experiment, suggests that skepticism should replace optimism concerning the radical claim that an anomalous quantum consciousness effect has been observed in a controlled laboratory setting.

“…In this article, they proposed a thought experiment which they claim, once confirmed, would rule out the hypotheses that collapse occurs by the consciousness of an observer. Also previously, Hall et al (1977), have performed an experiment and have shown that there is no experimental evidence for collapse of a wave function by consciousness, but recently, in contrast, Biermann (2003) has carried out a more accurate experiment in which consciousness has been demonstrated to collapse the wave function. The problem of wave function collapse taking place in the human mind is controversial at the moment and challenges are still ongoing.…”

How Can the Visual Quantum Information be Transferred to The Brain Intact, Collapsing There and Causing Consciousness?

The main problem which this paper tries to address is whether collapse of the wave function describing the state of a quantum mechanical system occurs, or, rather can occur in the brain of the observer or not. One of the first (relatively) detailed "collapse models" following the original abstract suggestion by von Neumann that collapse occurs in the brain of the observer and is related to consciousness, is the Orch OR model of Penrose and Hameroff. This model was first criticized by Tegmark on the ground that due to decoherence, quantum processing cannot occur in the human brain. This criticism was countered by saying that due to structural shielding, microtubules inside the neurons can be protected against the wet and warm environment inside the brain. Thaheld, however, in a number of papers argued that quantum visual information carried by the photons from the environment cannot reach the brain intact. In other words, the quantum states of the photons would collapse inside the human eye and only classical information would finally reach the brain and hence no collapse and quantum processing in the brain can take place. In this paper we advance a hypothesis that there is the possibility for the quantum states of photons to be transmitted to the brain in a quantum-like manner. Our approach is based on the quantum teleportation mechanism which includes both classical and quantum aspects of information transfer, but the process itself is wholly quantum mechanical.
