This work explores the excitation of a two-mode exciton-polariton condensate within a ring-shaped
trap, with each mode manifesting as a distinct eigenstate characterized by oppositely directed azimuthal
polariton currents. The coexistence of these condensate states is facilitated by a positive gain-loss bal-
ance for both states, sustained by external noncoherent laser pumping. We utilize interferometric methods
to investigate these states. Spherical wave interferometry visualizes the azimuthal polariton currents and
elucidates the spatial phase properties of the condensates. Plane-wave interferometry with a self-delayed
replica of the condensate’s photoluminescence provides a highly sensitive approach for estimating the
energy splitting between the states. The experimental observations are validated by numerical simula-
tions. The study emphasizes the potential of these condensates to form the basis for flux polariton qubits,
leveraging the superposition of current states within an annular optical trap.
