    Interference as an information-theoretic game
    22.03.2021
    theory allows marbles to "pass through 2 tubes at the same time", each quantum marble is worth 2 pennies. The value of the tokens is additive: for example, in order to win the game, Alice can either insert 4 classical marbles or 2 quantum marbles, as the total token value is in both cases equal to 4 pennies", explains Sebastian Horvat. On the other hand, recall that a quantum particle cannot pass through more than two locations at the same time: this is reflected in the fact ...

    we never put any financial burden on the reader or author of any of our articles. While we do ask for a publication fee of 100-200€, this can be waived without explanation and all our articles are obviously free to read (and published using a CC BY 4.0 creative commons license). Good science is not about fancy headlines and impact factors: We have no target rejection rate and every paper is judged only on its own scientific merit. The expected number of citations is not even ...

    Schrödinger’s Letter to Edington: Reconciling Mach’s and Boltzmann’s Philosophy
    13.09.2021
    text passage is saved in the second, intact copy of the letter (pages 3-4 of [1]). It reads: “ he is now a Nazi, I am sorry to say ”. It is not known who cut the text passage, and when and how the second copy was saved intact. Was it an attempt to hide Kirsch’s problematic past? Gerhard Kirsch, in fact, had been the head of a nucleus of the National Socialist Teachers’ Association at the University of Vienna from 1933 to 1937 [4]. From 1941 on, Kirsch headed the ...

    with very basic and simple modules each. Further, the wavelength based distribution scheme used allows users to be added and removed from the network without affecting the software or hardware of other users. Currently, the researchers have shown a 4 user fully connected network which they argue can easily support more connections. However, there is a limit. When asked if the limit is fundamental, Siddarth Joshi – an author of the paper replied: “The number if users is ...

Als gravitative Masse dient eine 2 mm große Goldkugel mit einem Gewicht von 90 mg. Das Torsionspendel besteht aus einem 4 cm langen und einem halben Millimeter dicken Glasstab, der an einer Glasfaser mit einem Durchmesser von ein paar Tausendstel Millimeter aufgehängt ist. Am Ende des Stabs sind jeweils ähnlich große Goldkugeln befestigt. Bislang ...
