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…
Understanding degenerate ground states of a protected quantum circuit in the presence of disorder
Joshua Dempster, Bo Fu, David G. Ferguson +2
A recent theoretical proposal suggests that a simple circuit utilizing two superinductors may produce a qubit with ground state degeneracy [P. Brooks et al., Phys. Rev. A 87, 05230…
