Quantum Noise Suppression at Scale with Crosstalk-Robust Gate Sets
Andy J. Goldschmidt, Emilio Peláez Cisneros, Ryan Sitler +3
We introduce crosstalk-robust gate sets, which are obtained using a novel, scalable optimal control problem exploiting locality. Through the suppression of pairwise quantum crossta…
Ramsey Envelope Modulation in NV Diamond Magnetometry
Jner Tzern Oon, Jiashen Tang, Connor A. Hart +4
Nitrogen-vacancy (NV) spin ensembles in diamond provide an advanced magnetic sensing platform, with applications in both the physical and life sciences. The development of isotopic…
Quantum Logic Enhanced Sensing in Solid-State Spin Ensembles
Nithya Arunkumar, Kevin S. Olsson, Jner Tzern Oon +7
We demonstrate quantum logic enhanced sensitivity for a macroscopic ensemble of solid-state, hybrid two-qubit sensors. We achieve a factor of 30 improvement in signal-to-noise rati…
Spin-Phonon Interaction in Yttrium Iron Garnet
Kevin S. Olsson, Jeongheon Choe, Martin Rodriguez-Vega +6
Spin-phonon interaction is an important channel for spin and energy relaxation in magnetic insulators. Understanding this interaction is critical for developing magnetic insulator-…
Generation of nitrogen-vacancy ensembles in diamond for quantum sensors: Optimization and scalability of CVD processes
Andrew M. Edmonds, Connor A. Hart, Matthew J. Turner +17
Ensembles of nitrogen-vacancy (NV) centers in diamond are a leading platform for practical quantum sensors. Reproducible and scalable fabrication of NV-ensembles with desired prope…
Interfacial Control of Dzyaloshinskii Moriya Interaction in Heavy Metal_Ferromagnetic Metal Thin Film Heterostructures
Xin Ma, Guoqiang Yu, Xiang Li +8
The interfacial Dzyaloshinskii Moriya Interaction (DMI) in ultrathin magnetic thin film heterostructures provides a new approach for controlling spin textures on mesoscopic length…
Current Control of Magnetic Anisotropy via Stress in a Ferromagnetic Metal Waveguide
Kyongmo An, Xin Ma, Chi-Feng Pai +6
We demonstrate that in-plane charge current can effectively control the spin precession resonance in an Al2O3/CoFeB/Ta heterostructure. Brillouin Light Scattering (BLS) was used to…
Magnons and Phonons Optically Driven Out of Local Equilibrium in a Magnetic Insulator
Kyongmo An, Kevin S. Olsson, Annie Weathers +9
Magnons are the energy quanta of fundamental spin excitations, namely spin waves, and they can make a considerable contribution to energy transport in some magnetic materials in a…
Control of Propagating Spin Waves via Spin Transfer Torque in a Metallic Bilayer Waveguide
Kyongmo An, Daniel R. Birt, Chi-Feng Pai +4
We investigate the effect of a direct current on propagating spin waves in a CoFeB/Ta bilayer structure. Using the micro-Brillouin light scattering technique, we observe that the s…
