Hermitian and unitary almost-companion matrices of polynomials on demand
L. A. Markovich, A. Migliore, A. Messina
We introduce the concept of Almost-Companion Matrix (ACM) by relaxing the non-derogatory property of the standard Companion Matrix (CM). That is, we define an ACM as a matrix whose…
Quantum memory assisted observable estimation
Liubov A. Markovich, Attaallah Almasi, Sina Zeytinoğlu +1
The estimation of many-qubit observables is an essential task of quantum information processing. The generally applicable approach is to decompose the observables into weighted sum…
Efficient and robust estimation of many-qubit Hamiltonians
Daniel Stilck França, Liubov A. Markovich, V. V. Dobrovitski +2
Characterizing the interactions and dynamics of quantum mechanical systems is an essential task in the development of quantum technologies. We propose an efficient protocol based o…
Highly parallel algorithm for the Ising ground state searching problem
A. Yavorsky, L. A. Markovich, E. A. Polyakov +1
Finding an energy minimum in the Ising model is an exemplar objective, associated with many combinatorial optimization problems, that is computationally hard in general, but occurs…
An example of interplay between Physics and Mathematics: Exact resolution of a new class of Riccati Equations
L. A. Markovich, R. Grimaudo, A. Messina +1
A novel recipe for exactly solving in finite terms a class of special differential Riccati equations is reported. Our procedure is entirely based on a successful resolution strateg…
Optimal nonlinear filtering of quantum state
V. I. Man'ko, L. A. Markovich
We extend the optimal filtering equation known from the Stratonovich filtering theory on the quantum process case. The used observation model is based on an indirect measurement me…
