On the construction of a quantum channel corresponding to non-commutative graph for a qubit interacting with quantum oscillator
G. G. Amosov, A. S. Mokeev, A. N. Pechen
We consider error correction, based on the theory of non-commutative graphs, for a model of a qubit interacting with quantum oscillator. The dynamics of the composite system is gov…
Non-commutative graphs based on finite-infinite system couplings: quantum error correction for a qubit coupled to a coherent field
G. G. Amosov, A. S. Mokeev, A. N. Pechen
Quantum error correction plays a key role for quantum information transmission and quantum computing. In this work, we develop and apply the theory of non-commutative operator grap…
Non-commutative graphs and quantum error correction for a two-mode quantum oscillator
G. G. Amosov, A. S. Mokeev, A. N. Pechen
An important topic in quantum information is the theory of error correction codes. Practical situations often involve quantum systems with states in an infinite dimensional Hilbert…
Measurement-assisted Landau-Zener transitions
A. N. Pechen, A. S. Trushechkin
Nonselective quantum measurements, i.e., measurements without reading the results, are often considered as a resource for manipulating quantum systems. In this work, we investigate…
