Unique determination and generation of rank two single-qubit quantum channels
Nina Kuklina, Vasilii Vasilenko, Boris Volkov +1
An important problem in quantum technologies is the generation of a target evolution of an open quantum system. A core component of this task is the ability to determine whether th…
Local finiteness of the number of reflections in semi-dispersing Minkowski billiards
Roman Barinov, Sergei Ivanov
We prove that in a semi-dispersing Minkowski billiard, that is a billiard in the complement of a collection of convex sets in a normed space with a smooth strictly convex norm, any…
If Edge Coloring is Hard under SETH, then SETH is False
Alexander S. Kulikov, Ivan Mihajlin
The Edge Coloring problem is notoriously hard: it is still unknown whether it can be solved in time (let alone ), where is the number of nodes of the inp…
Diverse efficiency of observable optimization for four-level quantum systems with higher-order traps
Alexander Pechen, Boris Volkov
In this work, we perform an analytical and numerical analysis of quantum landscapes for controlling special four-level quantum systems for which we prove that the null control is a…
Sketch of a Gauge Model of Gravity with SU(2) Symmetry in Minkowski space
Nikolay Marchuk
We propose a gauge model with the SU(2) symmetry, which describes a gravitational interaction of fundamental fermions (leptons and quarks) in the Minkowski space. In the Standard M…
Integrable open elliptic Toda chain with boundaries
A. Zotov
In this letter we discuss the classical integrable elliptic Toda chain proposed by I. Krichever. Our goal is to construct an open elliptic Toda chain with boundary terms. This is a…
