Conceptually, they arise for the same reason as non-normalizable states in quantum mechanics, and we will see how to deal with them when we start using the path ...

The Wave Function
... The limitations implied by the uncertainty relation as compared to classical physics may give the impression that something has been lost, that nature has prevented us, to an extent quantified by the uncertainty principle, from having complete information about the physical world. To someone wedded ...

Multi-component fractional quantum Hall states in graphene: S U(4
... an early work of Halperin on multi-component wavefunctions for the FQHE [9]. The FQHE problem in graphene differs from that in GaAs in two respects. First, in graphene, each electron has four components, because of two spin projections and two valleys, producing an approximate SU(4) symmetry when th ...

Quantum Theory
... The ‘picture’ that scientists obtain is called the spectrum of the atom or molecule: a plot of how much light is absorbed or emitted versus the wavelength or frequency of the light. Scientists analyze the spectrum of a substance to determine its composition or to better understand its properties. Fo ...

We begin by expressing in exact terms the regularities that are required in the laws of physics for information—as informally conceived, with its character ...

Strong no-go theorem for Gaussian quantum bit commitment

A bit commitment protocol is said to be secure if it prevents Alice from cheating (i.e., she cannot change the value of the bit she has committed) and Bob from ...
