Derivation of the robustness from the concurrence
Yu. S. Krynytskyi, A. R. Kuzmak
Adding the maximally mixed state with some weight to the entanglement system leads to disentanglement of the latter. For each predefined entangled state there exists a minimal valu…
Detecting the Lee-Yang zeros of a high-spin system by the evolution of probe spin
A. R. Kuzmak, V. M. Tkachuk
Recently in paper [Peng et al., Phys. Rev. Lett. 114, 010601 (2015)] the experimental observation of the Lee-Yang zeros of an Ising-type spin-1/2 bath, by measuring the coherence o…
Preparation of an arbitrary two-qubit quantum gate on two spins with an anisotropic Heisenberg interaction
A. R. Kuzmak
We consider the two-step method [A. R. Kuzmak and V. M. Tkachuk, Phys. Lett. A 378 (2014) 1469] for preparation of an arbitrary quantum gate on two spins with anisotropic Heisenber…
Probing the geometry of two-qubit state space by evolution
Andrzej M. Frydryszak, Maria Gieysztor, Andrij Kuzmak
We derive an explicit expressions for geometric description of state manifold obtained from evolution governed by a three parameter family of Hamiltonians covering most cases relat…
Geometry and speed of evolution for a spin-s system with long-range zz-type Ising interaction
Yu. S. Krynytskyi, A. R. Kuzmak
We study the evolution of a spin-s system described by the long-range zz-type Ising interaction. The Fubini-Study metric of the quantum state manifold defined by this evolution is…
