Distillability sudden death for two-qutrit states under an XY quantum environment

Witnessing Quantum Correlations in a Hybrid Qubit‐Qutrit System Under Intrinsic Decoherence

“…[48] Besides, it is invariant under local unitary operations. [48] To determine the analytical expression of the LQU (27) for our state (16), it is necessary to compute the eigenvalues of the matrix  AB (28). Hence, one needs to obtain the square root of 𝜌(t).…”

“…[17][18][19] Hence, many analytical tools, simulation techniques and several other methods for calculating and quantifying quantum correlations have been investigated to explore the separability of bipartite quantum systems. [20,21] Importantly, recent works shed light on studying quantum correlations for qubit-qutrit and qutritqutrit states, [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] which creates a fascinating future in quantum technologies. [39] Due to the possibility of maximum control of the associated Hilbert space, hybrid qubit-qudit systems have become increasingly important in the field of quantum information.…”

Distillability of Sudden Death in Qutrit-Qutrit Systems under Global Mixed Noise*

“…[28,29] The phenomenon of DSD was reported in our previous works for a two-qutrit system coupled to an 𝑋𝑌 spin chain, and effective methods for controlling the DSD were proposed. [32] In this regard, it is interesting to discuss the new effects resulting from the evolution of the system under a global mixed noise composed of a collective noise different from the multilocal noise. Furthermore, we notice that the DSD in the two-qutrit system under qutrit-flip noise has not been explored.…”
