“…where the populations of bath are defined by p n = e −En/kT 20 m=1 e −Em/kT (20) and |Ψ n (t) are the solutions to the Schrödinger equation for all initial states |Ψ n (0) = |ψ(0) ⊗ |n . The initial system state was chosen as a superposition state |ψ(0) = (|0 + |1 )/ √ 2.…”

“…At high temperatures random matrix theories [16], or classical trajectory simulations such as the Wigner method [17], can be used. Redfield theory [18,19] and its generalizations [20,21] can also be employed. But at the very low temperatures relevant to quantum computing technologies the options are more limited.…”

“…18,19 These derivations explicitly show that both forms of generalized Redfield theory account for non-Markovian behavior and have similar applicability requirements. [19][20][21] Specifically, since Redfield theory is tantamount to second-order perturbation theory in the system-bath coupling, truncation at low order is only accurate for η < 1, where η = max[ 2λ…”

“…The methodology has been employed for generating accurate benchmark results and has found numerous applications in chemical and condensed matter physics (for example, see Refs. [31][32][33][34][35][36][37][38][39][40][41][42][43]; it has also been extended to fermionic environments. [44][45][46] The i-QuAPI methodology employs a path integral 47,48 representation of the system's reduced density matrix in terms of localized system states.…”
