Background Entelechy (e.g., Hahnemann’s Vital Force, Vf), bears striking similarities to certain properties of quantum systems. Thus, the Vf is only indirectly observable via (centrifugally) expressed symptoms: a quantum property is only indirectly observable via its experimental effects. Consequently, a quantised Vf ‘gyroscopic’ metaphor is proposed where ‘axial’ rotation (represented by a wavefunction) undergoes dis-ease-induced retardation leading to Vf ‘precession’, i.e., symptom expression. Remedy-induced acceleration of axial rotation results in cure, via centrifugal removal of dis-ease, so precession/symptom expression ceases. The Vf ‘gyroscope’ is considered quantised partly because patients are observed during ‘discreet’ appointments, not continuously. Objective To develop this metaphor further by generating wavefunctions to represent the Vf in various states of dis-ease and health. Method Three wavefunctions are generated from secondary symptoms exhibited by the patient’s Vf, as observed by the practitioner. Three more wave functions are generated from analogous (unobserved) hypothetical states, representing the Vf evolving from health into a precursor dis-eased state. Results and discussion The evolution of therapeutic/dis-ease processes are imagined as transformations between these Vf wavefunctions, visualised as patient states on six of the nine points of an enneagram. The remaining three points represent practitioner states, ‘entangled’ with these processes. The Vf states may be divided into two groups - one indirectly observable via expressed symptoms, the other hypothetical - separated by a notional therapeutic ‘event horizon’. The practitioner, Janus-like, manages the therapeutic process by ‘negotiating’ between these two groups. Conclusion An interpretation of quantum theory called QBism (i.e., Quantum Bayesianism, in which a wavefunction represents only the total subjective information available to an assigning agent, not a shared separate objective reality), suggests these various Vf wavefunctions could represent Chalmers-like non-reductive information states, proposed as starting points for considering the influence of consciousness on the therapeutic process.

In addition to the important role of contextuality in foundations of quantum theory, this intrinsically quantum property has been identified as a potential resource for quantum advantage in different tasks. It is thus of fundamental importance to study contextuality from the point of view of resource theories, which provide a powerful framework for the formal treatment of a property as an operational resource. In this contribution, we review recent developments towards a resource theory of contextuality and connections with operational applications of this property. This article is part of the theme issue ‘Contextuality and probability in quantum mechanics and beyond’.

Background: Many complementary and alternative medicine modalities consider the vital force (Vf) an organism’s source of health and healing, Hahnemann’s notion of the Vf having similarities with quantum systems. Thus, the Vf is only indirectly observable via expressed symptoms: a quantum property is only indirectly observable via its observed experimental effects. Objective: To develop further a quantised gyroscopic metaphor of the Vf in which dis-ease slows axial rotation, causing the Vf to precess (i.e., express symptoms). The curative remedy accelerates axial rotation, throwing off the dis-ease, so precession (and symptom expression) cease. Method: Using earlier wave functions depending solely on observed patient symptoms and changes to them, 6 further wave functions are generated, representing the Vf in various states of dis-ease and health. Results: All 6 Vf wave functions can be arranged on 6 of the 9 points of an enneagram, the other 3 representing the practitioner. Conclusion: Transformations between the 6 Vf states are readily visualised. They may also be divided into two groups separated by a therapeutic “event horizon,” the practitioner being the “arbiter” between them. Thus, they could represent non-reductive information states, suitable as starting points for understanding the influence of consciousness on the therapeutic process.

Steering, a quantum property existing in some bipartite entangled systems, causes the local measurements on one part to change the state of the other part at any distance. In this paper, the dynamics of steering between two uncoupled oscillators in squeezed thermal, thermal and vacuum environments are compared. Assuming that the two oscillators are coupled to a common environment or two similar environments, the evolution of steering is obtained using Linblad equation in Born–Markov approximation. It is observed that when the two oscillators are initially in uni-modal squeezed states, the interaction with a common squeezed thermal environment induces steering between them after a short time. However, in other common and the two similar environments, steering does not appear. In addition, when two oscillators are initially in a squeezed thermal state, it is observed that steering decreases monotonically and disappears in a short time in common thermal, common vacuum and the two similar environments. Moreover, steering survives the most in a common squeezed thermal environment.

We present a general extension of the metadynamics allowing for an automatic sampling of quantum property manifolds (ASQPM) giving rise to functional landscapes. We illustrate our method on the example of biradical character in molecular systems.

Abstract What We Already Know about This Topic What This Article Tells Us That Is New Background Xenon is an elemental anesthetic with nine stable isotopes. Nuclear spin is a quantum property which may differ among isotopes. Xenon 131 (131Xe) has nuclear spin of 3/2, xenon 129 (129Xe) a nuclear spin of 1/2, and the other seven isotopes have no nuclear spin. This study was aimed to explore the effect of nuclear spin on xenon anesthetic potency. Methods Eighty C57BL/6 male mice (7 weeks old) were randomly divided into four groups, xenon 132 (132Xe), xenon 134 (134Xe), 131Xe, and 129Xe groups. Due to xenon’s low potency, loss of righting reflex ED50 for mice to xenon was determined with 0.50% isoflurane. Loss of righting reflex ED50 of isoflurane was also measured, and the loss of righting reflex ED50 values of the four xenon isotopes were then calculated. The exact polarizabilities of the isotopes were calculated. Results Combined with 0.50% isoflurane, the loss of righting reflex ED50 values were 15 ± 4%, 16 ± 5%, 22 ± 5%, and 23 ± 7% for 132Xe, 134Xe, 131Xe, and 129Xe, respectively. For xenon alone, the loss of righting reflex ED50 values of 132Xe, 134Xe, 131Xe, and 129Xe were 70 ± 4%, 72 ± 5%, 99 ± 5%, and 105 ± 7%, respectively. Four isotopes had a same exact polarizability of 3.60 Å3. Conclusions Xenon isotopes with nuclear spin are less potent than those without, and polarizability cannot account for the difference. The lower anesthetic potency of 129Xe may be the result of it participating in conscious processing and therefore partially antagonizing its own anesthetic potency. Nuclear spin is a quantum property, and our results are consistent with theories that implicate quantum mechanisms in consciousness.

Experimental tests on the quantum property of protein folding are discussed. It includes: the test of the instantaneousness of torsion transition through observation of protein structural change in a short time scale of microsecond; the test of non-Arrhenius temperature dependence of protein folding rate and other biomolecular conformational changes; and the search for the narrow spectral lines of the protein photo-folding.

The so - called ghost imaging represents a novel imaging technique which is especially appropriate to obtain images of objects located in positions difficult to reach or immersed in turbid media. It was first proposed as a novel quantum technology which exploits the key quantum property which is called entanglement. Subsequently, it has been shown theoretically and experimentally that the same technique can be realized also using classically correlated light beams. For a long time the topic of ghost imaging has been the object of an academic debate concerning the question whether quantum entanglement is necessary or not to realize it. In this talk we focus on the concrete question whether there are or not cases in which ghost imaging can offer better performances than standard imaging, and describe the status of the art in this matter.
