If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Abstract: I will explore the possibility of drawing definite theoretical assertions about “awareness”, including possible experimental falsification. Awareness will be regarded as a manifestation of a special kind of “information”, and, as such, formalised as an operational probabilistic theory (OPT) [1]. Awareness would correspond to “the feeling of the process” experienced by the OPT-systems involved in the process.



As a kind of information “awareness” is special in being “private”. Assuming

that such privacy is an in-principle one implies a number of interesting consequences. For example, according to a theorem about information privacy in OPTs [2], investigation will be restricted to OPTs that are essentially non classical, among which the most relevant instance is the quantum theory.

After presenting the OPT framework, assessing its methodological robustness in separating objective from theoretical elements, and examining postulates guaranteeing experimental control and falsifiability, I will compare postulates of relevant OPTs, and provide mathematical definitions of notions as holism, causality, complementarity, purification, and information privacy.

Finally, I will explore the hypothesis of “awareness as quantum coherence”, providing a list of motivations and consequences, and discussing the possibility of experimental tests in cognitive sciences, including the evaluation of the number of qubits involved in the awareness, the existence of complementary observables, and violations of local-realism bounds.
