Quantum enhanced electric field mapping within semiconductor devices
D. Scheller, F. Hrunski, J. H. Schwarberg +7
Semiconductor components based on silicon carbide (SiC) are a key component for high-power electronics. Their behavior is determined by the interplay of charges and electric fields…
Photonic crystal cavity IQ modulators in thin-film lithium niobate for coherent communications
Hugo Larocque, Dashiell L. P. Vitullo, Alexander Sludds +13
Thin-Film Lithium Niobate (TFLN) is an emerging integrated photonic platform showing great promise due to its large second-order nonlinearity at microwave and optical frequencies,…

Arrays of coupled phonon cavities each including an impurity qubit in silicon are considered. We study experimentally feasible architectures that can exhibit quantum many-body phas…
Phonitons as a sound-based analogue of cavity quantum electrodynamics
O. O. Soykal, Rusko Ruskov, Charles Tahan
A quantum mechanical superposition of a long-lived, localized phonon and a matter excitation is described. We identify a realization in strained silicon: a low-lying donor transiti…
Size-dependence of Strong-Coupling Between Nanomagnets and Photonic Cavities
Ö. O. Soykal, M. E. Flatté
The coherent dynamics of a coupled photonic cavity and a nanomagnet is explored as a function of nanomagnet size. For sufficiently strong coupling eigenstates involving highly enta…
Strong-field interactions between a nanomagnet and a photonic cavity
Öney O. Soykal, M. E. Flatté
We analyze the interaction of a nanomagnet with a single photonic mode of a microcavity in a fully quantum-mechanical treatment and find that exceptionally large quantum-coherent m…
