A Traveling-Wave Parametric Amplifier With Integrated Diplexers
C. Denney, K. Genter, K. Cicak +4
Traveling-Wave Parametric Amplifiers (TWPAs) are ubiquitous in superconducting circuit readout, providing high gain with near-quantum-limited noise performance across a wide bandwi…
Qubit measurement and backaction in a multimode nonreciprocal system
B. T. Miller, Lindsay Orr, A. Metelmann +1
High fidelity qubit readout is a cornerstone for quantum information protocols. In traditional superconducting qubit readout, a chain of microwave amplifiers and nonreciprocal comp…
Cryogenic photonic link using an extended-InGaAs photodiode and short pulse illumination towards high-fidelity drive of superconducting qubits
Takuma Nakamura, Dahyeon Lee, Jason Horng +3
We investigate short pulse illumination of a high-speed extended-InGaAs photodiode at cryogenic temperatures towards its use in control and readout of superconducting qubits. First…
A Traveling-Wave Parametric Amplifier and Converter
M. Malnou, B. T. Miller, J. A. Estrada +5
High-fidelity qubit measurement is a critical element of all quantum computing architectures. In superconducting systems, qubits are typically measured by probing a readout resonat…
Low-noise cryogenic microwave amplifier characterization with a calibrated noise source
M. Malnou, T. F. Q. Larson, J. D. Teufel +2
Parametric amplifiers have become a workhorse in superconducting quantum computing, however research and development of these devices has been hampered by inconsistent, and sometim…
Fast, tunable, high fidelity cZ-gates between superconducting qubits with parametric microwave control of ZZ-coupling
X. Y. Jin, K. Cicak, Z. Parrott +6
Future quantum information processors require tunable coupling architectures that can produce high fidelity logical gates between two or more qubits. Parametric coupling is a power…
