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…
Scanned SQUID Microscope with High-speed Electrical Connectivity
Ian W. Haygood, Bochao Xu, John Biesecker +1
We report on a scanned superconducting quantum interference device (SQUID) microscope operating in a cryogen-free cryostat, with the capability of up to forty RF connections with 2…
Picosecond Josephson Samplers: Modeling and Measurements
Logan Howe, Bart van Zeghbroeck, David Olaya +4
Measurement of signals generated by superconducting Josephson junction (JJ) circuits require ultra-fast components located in close proximity to the generating circuitry. We report…
Single Flux Quantum-Based Digital Control of Superconducting Qubits in a Multi-Chip Module
Chuan-Hong Liu, Andrew Ballard, David Olaya +15
The single flux quantum (SFQ) digital superconducting logic family has been proposed for the scalable control of next-generation superconducting qubit arrays. In the initial implem…
Demonstration of Superconducting Optoelectronic Single-Photon Synapses
