Indistinguishable Sceneries
In this paper we give a counter example to a conjecture mentioned in Benjamini and Kesten (1996) about distinguishing sceneries by observing them along a simple random walk, giving an explicit construction of 2 @0 sceneries that are all pairwise indistinguishable.
متن کاملStatistics of indistinguishable particles.
The wave function of a system containing identical particles takes into account the relationship between a particle's intrinsic spin and its statistical property. Specifically, the exchange of two identical particles having odd-half-integer spin results in the wave function changing sign, whereas the exchange of two identical particles having integer spin is accompanied by no such sign change. ...
متن کاملIdentifying Perceptually Indistinguishable Objects
This paper describes a cognitively plausible computational theory of identifying perceptually indistinguishable objects (PIOs) based on a set of experiments which were designed to identify the knowledge and perceptual cues that people use for this purpose. Identifying a PIO in this context means connecting sensor data from some physical object either to a new mental level symbol or to the corre...
متن کاملBlindspot: Indistinguishable Anonymous Communications
Communication anonymity is a key requirement for individuals under targeted surveillance. Practical anonymous communications also require indistinguishability — an adversary should be unable to distinguish between anonymised and nonanonymised traffic for a given user. We propose Blindspot, a design for high-latency anonymous communications that offers indistinguishability and unobservability un...
متن کاملDiscerning “indistinguishable” quantum systems
In a series of recent papers, Simon Saunders, Fred Muller and Michael Seevinck have collectively argued, against the folklore, that some non-trivial version of Leibniz’s principle of the identity of indiscernibles is upheld in quantum mechanics. They argue that all particles—fermions, paraparticles, anyons, even bosons—may be weakly discerned by some physical relation. Here I show that their ar...
