Superconducting Flux Memory for Cryogenic Applications
Gregory R. Boyd, Jeremy Clark, Mark Covington +15
We report the development of flux memory for use with superconducting circuits. This technology stores persistent currents in superconducting loops on-chip to be used to provide fl…
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…
Tunable Resonator Integrated Magnetometry
Colin Stack, Brian Sears, Aruna Ramanayaka +3
The quantum-technology revolution is reshaping computing, sensing, and communication. In magnetometry, recent advances leverage precise control of spin qubits and color centers in…
Projected dipole moments of individual two-level defects extracted using circuit quantum electrodynamics
Bahman Sarabi, Aruna N. Ramanayaka, Alexander L. Burin +2
Material-based two-level systems (TLSs), appearing as defects in low-temperature devices including superconducting qubits and photon detectors, are difficult to characterize. In th…
Superconducting TiN Films Sputtered over a Large Range of Substrate DC Bias
H. M. Iftekhar Jaim, J. A. Aguilar, B. Sarabi +5
We have investigated properties of superconducting titanium nitride (TiN) films that were sputtered over a large range of RF-induced DC bias voltage applied to the substrate. Films…
Cavity quantum electrodynamics using a near-resonance two-level system: emergence of the Glauber state
Bahman Sarabi, Aruna N. Ramanayaka, Alexander L. Burin +2
Random tunneling two-level systems (TLSs) in dielectrics have been of interest recently because they adversely affect the performance of superconducting qubits. The coupling of TLS…
Effect of rotation of the polarization of linearly polarized microwaves on the radiation-induced magnetoresistance oscillations
A. N. Ramanayaka, R. G. Mani, J. Iñarrea +1
Light-matter coupling is investigated by rotating, by an angle θ, the polarization of linearly polarized microwaves with respect to the long-axis of GaAs/AlGaAs Hall-bar electron d…
Observation of linear-polarization-sensitivity in the microwave-radiation-induced magnetoresistance oscillations
R. G. Mani, A. N. Ramanayaka, W. Wegscheider
In the quasi two-dimensional GaAs/AlGaAs system, we investigate the effect of rotating \textit{in-situ} the electric field of linearly polarized microwaves relative to the current,…
Transport study of Berry's phase, the resistivity rule, and quantum Hall effect in graphite
Aruna N. Ramanayaka, R. G. Mani
Transport measurements indicate strong oscillations in the Hall-,, and the diagonal-, , resistances and exhibit Hall plateaus at the lowest temperatures, in three-d…
