# lindbladian.m

From Spinach Documentation Wiki

Generates a Lindblad superoperator from user-specified left-side and right-side product superoperators and calibrates it using the experimental relaxation rate of a user-specified state.

## Syntax

R=lindbladian(A_left,A_right,rho,rlx_rate)

## Arguments

A_left - left side product superoperator of the interaction that is causing relaxation (see operator.m and hamiltonian.m) A_right - right side product superoperator of the same interaction rho - the state vector whose relaxation rate is known from the experiment rlx_rate - experimental relaxation rate of rho

## Outputs

R - Lindblad relaxation superoperator indu- ced by the interaction A, such that <rho|R|rho>/norm(rho,2)^2 = -rlx_rate
