Effect of Non-Markovian Hybrid Bath on Quantum Entanglement and Quantum Dense Coding in Heisenberg XYZ Spin Chain Model
Because a heat bath forming the surrounding environment of an open quantum system always contains Bosons and Fermions at the same time, it is more practical to describe the heat bath using a mixed bath rather than a single Bosonic or Fermionic bath. The dynamical evolution properties of the quantum entanglement and quantum dense encoding channel capacity of the Heisenberg XYZ spin chain model coupled with a non-Markovian Bosonic bath and Fermionic bath simultaneously were studied and compared with a non-Markovian single bath using the non-Markovian quantum state diffusion method. The numerical simulation results show that compared with a non-Markovian single bath, the Heisenberg spin chain model coupled with the non-Markovian hybrid bath has higher entanglement, better quantum dense coding, and a longer relaxation time. These results show that the non-Markovian hybrid bath has more advantages than the non-Markovian single bath. A system in the non-Markovian hybrid bath improved quantum entanglement and optimized quantum dense coding.
