Two-parameter families of matrix product operator integrals of motion in Heisenberg spin chains
Vsevolod I. Yashin
Recently, Fendley et al. (2025) [arXiv:2511.04674] revealed a new simple way to demonstrate the integrability of XYZ Heisenberg model by constructing a one-parameter family of inte…
Further improvements to stabilizer simulation theory: classical rewriting of CSS-preserving stabilizer circuits, quadratic form expansions of stabilizer operations, and framed hidden variable models
Vsevolod I. Yashin, Vladimir V. Yatsulevich, Aleksey K. Fedorov +1
Simulation of stabilizer circuits is a well-studied problem in quantum information processing, with a number of highly optimized algorithms available. Yet, we argue that further im…
A streamlined demonstration that stabilizer circuits simulation reduces to Boolean linear algebra
Vsevolod I. Yashin
Gottesman-Knill theorem states that computations on stabilizer circuits can be simulated on a classical computer, conventional simulation algorithms extensively use linear algebra…
Characterization of non-adaptive Clifford channels
Vsevolod I. Yashin, Maria A. Elovenkova
Stabilizer circuits arise in almost every area of quantum computation and communication, so there is interest in studying them from an information-theoretic perspective, i.e. as qu…
Minimizing the negativity of quantum circuits in overcomplete quasiprobability representations
Denis A. Kulikov, Vsevolod I. Yashin, Aleksey K. Fedorov +1
The problem of simulatability of quantum processes using classical resources plays a cornerstone role for quantum computing. Quantum circuits can be simulated classically, e.g., us…
Integrable Floquet systems related to logarithmic conformal field theory
Vsevolod I. Yashin, Denis V. Kurlov, Aleksey K. Fedorov +1
We study an integrable Floquet quantum system related to lattice statistical systems in the universality class of dense polymers. These systems are described by a particular non-un…
The Extension of Unital Completely Positive Semigroups on Operator Systems to Semigroups on -algebras
V. I. Yashin
The study of open quantum systems relies on the notion of unital completely positive semigroups on -algebras representing physical systems. The natural generalisation would be…
Lie-algebraic approach to one-dimensional translationally invariant free-fermionic dissipative systems
L. R. Bakker, V. I. Yashin, D. V. Kurlov +2
We study dissipative translationally invariant free-fermionic theories with quadratic Liouvillians. Using a Lie-algebraic approach, we solve the Lindblad equation and find the dens…
Quantum information aspects of approximate position measurement
A. S. Holevo, V. I. Yashin
We perform a quantum information analysis for multi-mode Gaussian approximate position measurements, underlying noisy homodyning in quantum optics. The "Gaussian maximizer" propert…
Properties of operator systems, corresponding to channels
V. I. Yashin
It was shown in arXiv:0906.2527, that in finite-dimensional Hilbert spaces each operator system corresponds to some channel, for which this operator system will be an operator grap…
