... Even more striking is the fact that all WMs equally agree with the past and future strong measurements. While it is not surprising that the noon WMs confirm the morning strong outcomes, the equal degree of agreement with the evening ones can suggest that they anticipate them.

... Closed-orbit theory is a semiclassical method for calculating photoabsorption cross sections. This method is based on the observation that to calculate this cross section it is only necessary to obtain the Green’s function for points near the nucleus when the initial state is compact. Thus in a semi ...

Leftover Hashing Against Quantum Side Information
... In Section II, we discuss various aspects of the smooth entropy framework, which will be needed for our proof. We then give the proof of the General Leftover Hash Lemma (Lemma 1) in Section III. More precisely, we provide statements of the Leftover Hash Lemma for two-universal and -almost two-univer ...

Computational Complexity: A Modern Approach

The players are separated by a light year (say), each accompanied by an assistant of the experimenter.

Probability amplitude

In quantum mechanics, a probability amplitude is a complex number used in describing the behaviour of systems. The modulus squared of this quantity represents a probability or probability density.Probability amplitudes provide a relationship between the wave function (or, more generally, of a quantum state vector) of a system and the results of observations of that system, a link first proposed by Max Born. Interpretation of values of a wave function as the probability amplitude is a pillar of the Copenhagen interpretation of quantum mechanics. In fact, the properties of the space of wave functions were being used to make physical predictions (such as emissions from atoms being at certain discrete energies) before any physical interpretation of a particular function was offered. Born was awarded half of the 1954 Nobel Prize in Physics for this understanding (see #References), and the probability thus calculated is sometimes called the ""Born probability"". These probabilistic concepts, namely the probability density and quantum measurements, were vigorously contested at the time by the original physicists working on the theory, such as Schrödinger and Einstein. It is the source of the mysterious consequences and philosophical difficulties in the interpretations of quantum mechanics—topics that continue to be debated even today.
