Classical analog of qubit logic based on a magnon Bose–Einstein condensate

Abstract

Adding to the significant interest in quantum computing schemes, this work focuses on classical analogs for which entanglement is not required. Specifically, this work demonstrates through micromagnetic numerical simulations the use of wavevector-selective parametric pumping to controllably initialize and manipulate a room-temperature two-component magnon condensate on the Bloch sphere and reveals the possibility of Rabi-like oscillations in the wavevector domain.
