چکیده

The implications arising from the “Schrödinger’s cat” thought experiment have led some authors to argue that observation of a measurement by a conscious observer is required to collapse quantum wave-functions. Here we combine Schrödinger’s experimental paradigm with a system for splitting the information about the quantum state between two observers, thereby allowing distinct outcomes to be recorded without either observer knowing the state of the measured quantum event. Our results imply that to collapse a quantum wave-function, measurement alone, rather than conscious observation of a measurement, is sufficient. RÉSUMÉ. Les implications provenant de l’expérience imaginaire du "chat de Schrödinger" ont amené certains auteurs à prétendre que la réduction du paquet d’ondes quantique nécessite l’observation du résultat d’une mesure par un être conscient. Ici, nous combinons le paradigme expérimental de Schrödinger avec un système qui partage entre deux observateurs l’information relative à l’état quantique, de sorte qu'on peut enregistrer les résultats séparément sans qu'aucun observateur n'ait connaissance de l'état de l'événement quantique. Nos résultats impliquent que pour réduire la fonction d'onde quantique, l'opération de mesure seule suffit, sans observation consciente..

The Double Quantum Dot Feline Cousin of Schrödinger’s Cat: An Experimental Testbed for a Discourse on Quantum Measurement Dichotomies

Quantum measurement theory is a perplexing discipline fraught with paradoxes and dichotomies. Here we discuss a gedanken experiment that uses a popular testbed namely, a coupled double quantum dot system to revisit intriguing questions about the collapse of wavefunctions, irreversibility, objective reality and the actualization of a measurement outcome. Corresponding author. E-mail: bandy@quant...

A Flea on Schrödinger’s Cat

We propose a technical reformulation of the measurement problem of quantum mechanics, which is based on the postulate that the final state of a measurement is classical; this accords with experimental practice as well as with Bohr’s views. Unlike the usual formulation (in which the post-measurement state is a unit vector in Hilbert space), our version actually opens the possibility of admitting...

The Neutrosophic Logic View to Schrödinger’s Cat Paradox

As already known, Schrödinger equation is the most used equation to describe non-relativistic quantum systems. Its relativistic version was developed by Klein-Gordon and Dirac, but Schrödinger equation has wide applicability in particular because it resembles classical wave dynamics. For introduction to non-relativistic quantum mechanics, see [1]. Schrödinger equation begins with definition of ...

Proposed Experiments to Determine if There is a Connection Between Biological Nonlocality and Consciousness

Experiments are proposed based upon present research in an attempt to deal with the decades old question as to the possible role consciousness plays in the discontinuous collapse of the wave-function. Other interrelated problem areas will be investigated including the influence of mental events upon neuronal events, the entanglement of neurons in the brain and the transference of conscious subj...

A Simulation for Neurophotonic Quantum Computation in Visual Pathways

One of the answers to the measurement problem in quantum theory is given by the Copenhagen-Interpretation of quantum theory (i.e. orthodox quantum theory) in which the wave function collapse happens in (by) the mind of observer. In fact, at first, great scientists like Von Neumann, London, Bauer and Wigner (initially) believed that the wave function collapse occurs in the brain or is caused by ...
