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…
Variational tight-binding method for simulating large superconducting circuits
D. K. Weiss, Wade DeGottardi, Jens Koch +1
We generalize solid-state tight-binding techniques for the spectral analysis of large superconducting circuits. We find that tight-binding states can be better suited for approxima…
Fast, Lifetime-Preserving Readout for High-Coherence Quantum Annealers
Jeffrey A. Grover, James I. Basham, Alexander Marakov +15
We demonstrate, for the first time, that a quantum flux parametron (QFP) is capable of acting as both isolator and amplifier in the readout circuit of a capacitively shunted flux q…
Spectrum and Coherence Properties of the Current-Mirror Qubit
D. K. Weiss, Andy C. Y. Li, D. G. Ferguson +1
The current-mirror circuit [A. Kitaev, arXiv:cond-mat/0609441 (2006)] exhibits a robust ground-state degeneracy and wave functions with disjoint support for appropriate circuit par…
Exploring More-Coherent Quantum Annealing
Sergey Novikov, Robert Hinkey, Steven Disseler +6
In the quest to reboot computing, quantum annealing (QA) is an interesting candidate for a new capability. While it has not demonstrated an advantage over classical computing on a…
High Saturation Power Josephson Parametric Amplifier with GHz Bandwidth
O. Naaman, D. G. Ferguson, R. J. Epstein
We present design and simulation of a Josephson parametric amplifier with bandwidth exceeding 1.6 GHz, and with high saturation power approaching -90 dBm at a gain of 22.8 dB. An i…
