    Coupling

## Description

- description: "Prolongation of a pure dephasing time of a qubit by coupling with
    another one with longer dephasing times is theoretically studied.  \r\nThe analysis
    is performed for a paired-qubit, both of which interact in an anisotropic Heisenberg
    manner, using the Lindblad master equation.  \r\nThe pure dephasing time is found
    to be a nontrivially increasing function of in-plane but not longitudinal components
    of the interaction, and to saturate finally, where a strong coupling-like state
    of those qubits is suggested.\r\nThe two-qubit system well suits NV<sup>ー</sup>
    centers in diamond where one (the other) is that located at a surface of (embeded
    inside) the diamond, so that\r\nfeasible experiments with the centers are proposed
    to test the results.  \r\nThe finding would offer a solution to challenge in applications
    of those qubits.\r\n"
