Phonon- and magnon-mediated decoherence of a magnonic qubit
Vemund Falch, Arne Brataas, Jeroen Danon
We investigate the decoherence of magnonic qubits in small ferromagnetic insulators and compute the relaxation and dephasing rates due to magnon-phonon and magnon-magnon interactio…
Magnon and photon blockade in a hybrid antiferromagnet-cavity quantum system
Vemund Falch, Arne Brataas, Alireza Qaiumzadeh
We investigate both magnon and photon blockade for an antiferromagnetic insulator coupled to a linearly polarized cavity mode. We focus on the cross-Kerr nonlinearity between the t…
Second-order correlation and squeezing of photons in cavities with ultrastrong magnon-photon interactions
Vemund Falch, Arne Brataas, Alireza Qaiumzadeh
We investigate the second-order photon correlation function in cavity-magnon systems, focusing on ferromagnetic and antiferromagnetic cavities within the ultrastrong coupling regim…
Impact of spin torques and spin pumping phenomena on magnon-plasmon polaritons in antiferromagnetic insulator-semiconductor heterostructures
Vemund Falch, Jeroen Danon, Alireza Qaiumzadeh +1
We investigate the impact of spin torque and spin pumping on the surface magnon polariton dispersion in a antiferromagnetic insulator-semiconductor heterostructure. In the bilayer…
Giant magnetoanisotropy in the Josephson effect and switching of staggered order in antiferromagnets
Vemund Falch, Jacob Linder
We predict that the amplitude of the Josephson current through an antiferromagnetic weak link changes by several orders of magnitude upon rotation of the Néel order parameter chara…
Quantum Poker A game for quantum computers suitable for benchmarking error mitigation techniques on NISQ devices
Franz G. Fuchs, Vemund Falch, Christian Johnsen
Quantum computers are on the verge of becoming a commercially available reality. They represent a paradigm shift in computing, with a steep learning gradient. The creation of games…
