  2. Superposition principle - Wikipedia

    en.wikipedia.org/wiki/Superposition_principle

    The superposition principle, [1] also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.

  3. Quantum superposition - Wikipedia

    en.wikipedia.org/wiki/Quantum_superposition

    The non-classical nature of the superposition process is brought out clearly if we consider the superposition of two states, A and B, such that there exists an observation which, when made on the system in state A, is certain to lead to one particular result, a say, and when made on the system in state B is certain to lead to some different ...

  4. Schrödinger's cat - Wikipedia

    en.wikipedia.org/wiki/Schrödinger's_cat

    In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead, while it is unobserved in a closed box, as a result of its fate being linked to a random subatomic event that may or may not

  5. Bell test - Wikipedia

    en.wikipedia.org/wiki/Bell_test

    The experiments are commonly interpreted to rule out local hidden-variable theories, and in 2015 an experiment was performed that is not subject to either the locality loophole or the detection loophole (Hensen et al. [10]). An experiment free of the locality loophole is one where for each separate measurement and in each wing of the experiment ...

  6. Basis set superposition error - Wikipedia

    en.wikipedia.org/wiki/Basis_set_superposition_error

    Whereas in the CHA model, those orbitals have no greater intrinsic freedom and therefore the correction treats all fragments equally. [10] The errors inherent in either BSSE correction disappear more rapidly than the total value of BSSE in larger basis sets. [11]

  7. Measurement problem - Wikipedia

    en.wikipedia.org/wiki/Measurement_problem

    In quantum mechanics, the measurement problem is the problem of definite outcomes: quantum systems have superpositions but quantum measurements only give one definite result. [ 1 ] [ 2 ] The wave function in quantum mechanics evolves deterministically according to the Schrödinger equation as a linear superposition of different states.

  8. Elitzur–Vaidman bomb tester - Wikipedia

    en.wikipedia.org/wiki/Elitzur–Vaidman_bomb_tester

    The Elitzur–Vaidman bomb-tester is a quantum mechanics thought experiment that uses interaction-free measurements to verify that a bomb is functional without having to detonate it. It was conceived in 1993 by Avshalom Elitzur and Lev Vaidman. Since their publication, real-world experiments have confirmed that their theoretical method works as ...

  9. Williams–Landel–Ferry equation - Wikipedia

    en.wikipedia.org/wiki/Williams–Landel–Ferry...

    The WLF equation is a consequence of time–temperature superposition (TTSP), which mathematically is an application of Boltzmann's superposition principle. It is TTSP, not WLF, that allows the assembly of a compliance master curve that spans more time, or frequency, than afforded by the time available for experimentation or the frequency range ...
