Quantum master equations are an important tool in quantum optics and quantum information theory. For systems comprising a small to medium number of atoms (or qubits), the non-truncated equations are usually solved numerically.

Nov 1, 2016 · In this paper, we present a group-theoretical superoperator method that helps solving these equations. To do so, we exploit the SU(4)-symmetry ...
To solve the corresponding quantum master equations, three approaches have been taken: First, one focuses on the case of one atom. Second, one truncates eq. (1) ...
Specifically, any permutation symmetric density matrix may be represented as a linear combination of generalized Dicke states ρ = q,qz,σz α q,qz,σz D q,qz,σz ..
To show the need for a generalization, we first introduce Dicke states and show that they do not suffice to solve quantum master equations involving terms such ...
Abstract. Dicke states are completely symmetric states of multiple qubits (2-level systems), and qudit Dicke states are their d-level generalization.
May 25, 2010 · Here we present a [2^(N+1)-1]-parameter family of N-qubit "X states" that embrace all those families, generalizing previously defined states for two qubits.
We conduct a concrete comparison with two generalized Dicke state preparation circuits. We perform noisy simulations and experiments using real quantum machines ...
