Programmable CMOS DAC Operating in Cryogenic Environments for Controlling Superconducting Qubits
A. Pelteku, D. Reitz, M. Covington +15
This paper presents the design and test results of a CMOS current-based Digital to Analog Converter (DAC) that operates at cryogenic temperatures and that can be used to precisely…
Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Transmon Phase Gates Controlled by Superconducting Soliton DAC
Derek Reitz, Tony X. Zhou, Aditya Sharma +10
We introduce a superconducting digital-to-analog converter (DAC) that filters control noise, provides native multiplexing, performs quantum gates in nanoseconds, and can be control…
Spin transport from order to disorder
Derek Reitz, Yaroslav Tserkovnyak
Schwinger boson mean-field theory (SBMFT) is a non-perturbative approach which treats ordered and disordered phases of magnetic systems on equal footing. We leverage its versatilit…
Observation of nuclear-spin Seebeck effect
T. Kikkawa, D. Reitz, H. Ito +10
Thermoelectric effects have been applied to power generators and temperature sensors that convert waste heat into electricity. The effects, however, have been limited to electrons…
Observation of magnon-polarons in a uniaxial antiferromagnetic insulator
Junxue Li, Haakon T. Simensen, Derek Reitz +6
Magnon-polarons, a type of hybridized excitations between magnons and phonons, were first reported in yttrium iron garnet as anomalies in the spin Seebeck effect responses. Here we…
Short-range Thermal Magnon Diffusion in Magnetic Garnet
Kyongmo An, Ryuhei Kohno, Nicolas Thiery +8
Using the spin Seebeck effect (SSE), we study the propagation distance of thermal spin currents inside a magnetic insulator thin film in the short-range regime. We disambiguate spi…
Spin Seebeck Effect near the Antiferromagnetic Spin-Flop Transition
Derek Reitz, Junxue Li, Wei Yuan +2
We develop a low-temperature, long-wavelength theory for the interfacial spin Seebeck effect (SSE) in easy-axis antiferromagnets. The field-induced spin-flop (SF) transition of Née…
Viscous dynamics of vortices in a ferromagnetic film
Derek Reitz, Anirban Ghosh, Oleg Tchernyshyov
We derive viscous forces for vortices in a thin-film ferromagnet. The viscous force acting on vortex is a linear superposition $\mathbf F_i = - \sum_{j} \hat{D}_{ij} \mathbf V_…
