On permutation symmetry of subradiant states and its application
Abstract
Group theory is an extremely powerful mathematical tool for many physical problems, in particular for classification of quantum states by exploiting their symmetry. In this paper, we address symmetry properties of single- and double-excited subradiant states and show how they can be useful for experimental design of sidewise excitation method for generation of subradiant states. Experimental realization of the considered method can be achieved using superconducting qubits in circuit quantum electrodynamics.
