Coherence-limited digital control of a superconducting qubit using a Josephson pulse generator at 3 K
M. A. Castellanos-Beltran, A. J. Sirois, L. Howe +4
Compared to traditional semiconductor control electronics (TSCE) located at room temperature, cryogenic single flux quantum (SFQ) electronics can provide qubit measurement and cont…
Measurable Improvement in Multi-Qubit Readout Using a Kinetic Inductance Traveling Wave Parametric Amplifier
M. A. Castellanos-Beltran, L. Howe, A. Giachero +4
Increasing the size and complexity of quantum information systems requires highly-multiplexed readout architectures, as well as amplifier chains operating near the quantum limit (Q…
Transmon qubit modeling and characterization for Dark Matter search
R. Moretti, D. Labranca, P. Campana +21
This study presents the design, simulation, and experimental characterization of a superconducting transmon qubit circuit prototype for potential applications in dark matter detect…
Digital control of a superconducting qubit using a Josephson pulse generator at 3 K
L. Howe, M. Castellanos-Beltran, A. J. Sirois +5
Scaling of quantum computers to fault-tolerant levels relies critically on the integration of energy-efficient, stable, and reproducible qubit control and readout electronics. In c…
