TL;DR: In this article, a microwave photon counter based on the current-biased Josephson junction is proposed, which is tuned to absorb single microwave photons from the incident field, after which it tunnels into a classically observable voltage state.

TL;DR: In this paper, the authors derived raising and lowering differential recurrence relations for polynomials orthogonal with respect to a weight function supported in the real line under some integrability conditions.

TL;DR: It is shown that the moment generating function, or the Laplace transform of the probability density function of this linear statistics, can be expressed as the ratio of Hankel determinants and as an integral involving a particular third Painleve function.

TL;DR: This paper compute two important information-theoretic quantities which arise in the application of multiple-input multiple-output (MIMO) antenna wireless communication systems: the distribution of the mutual information of multiantenna Gaussian channels, and the Gallager random coding upper bound on the error probability achievable by finite-length channel codes.

TL;DR: In this paper, the authors study the simplest deformation on a sequence of orthogonal polynomials and show that the resulting deformation induces an irregular singular point at infinity in addition to three regular singular points of the hypergeometric equation satisfied by the Jacobi polynomorphism.
