... systems with six levels. Using numerical, computer-algebraic and analytic methods, various partial results have been obtained all of which are compatible with the conjecture that no more than three MU bases exist. I will emphasise the case of MU bases consisting of product states only for which stro ...

... In an atom optical interferometer shown below, a highly collimated beam of atoms interacts with three regions of standing-wave laser fields (the intensity of the standing wave modulates the atomic wavefunctions), are created by lasers of wavelength 590 nm. (a) If the atoms are sodium (A = 23) and de ...

The non-abelian calibrating quantum field theory describing the strong mutual interactions between quarks and gluons is named chromo-dynamics (QCD). The independent existence of quarks and gluons is impossible ...

... And today, we don’t believe quantum computers can solve NP-complete problems in polynomial time in general (though not surprisingly, we can’t prove it) Bennett et al. 1997: “Quantum magic” won’t be enough If you throw away the problem structure, and just consider an abstract “landscape” of 2n possib ...

... Another important feature of LQG is that it is the most serious attempt to perform a full non-perturbative quantization of the gravitational field by itself. It is an attempt to answer the following question: can we quantize the gravitational degrees of freedom without considering matter on the firs ...

This strategy feeds directly into the considerations in this paper. The physical reason why winding states are well-behaved is easy to understand. The obvious pro ...
