In the emerging field of cavity optomagnonics, photons are coupled coherently to magnons in solid-state systems. These new systems promising for implementing hybrid quantum technologies. Being able prepare Fock states such platforms is an essential step towards implementation information schemes. We propose a magnon-heralding protocol generate magnon state by detecting optical photon. Due peculiarities optomagnonic coupling, involves two distinct photon modes. Solving Langevin equations...
The ground state properties of the two-dimensional ${J}_{1}\ensuremath{-}{J}_{2}$-model are very challenging to analyze via classical numerical methods due high level frustration. This makes model a promising candidate for which quantum computers could be helpful possibly explore regimes that cannot reach. is spin composed Heisenberg interactions along rectangular lattice edges and diagonal between next-nearest-neighbor spins. We propose an ansatz variational eigensolver approximate...
