Architectural scaling tradeoffs in modular 3D bosonic quantum processors
Shaojiang Zhu, Ugur Alyanak, Tanay Roy +7
We propose a modular three-dimensional bosonic quantum processor built from repeatable coupled-cavity modules linked by configurable interconnect networks. Using hardware-motivated…
Disentangling the Impact of Quasiparticles and Two-Level Systems on the Statistics of Superconducting Qubit Lifetime
Shaojiang Zhu, Xinyuan You, Ugur Alyanak +8
Temporal fluctuations in the superconducting qubit lifetime, , bring up additional challenges in building a fault-tolerant quantum computer. While the exact mechanisms remain…
High-Order Qubit Dephasing at Sweet Spots by Non-Gaussian Fluctuators: Symmetry Breaking and Floquet Protection
Ziwen Huang, Xinyuan You, Ugur Alyanak +3
Although the Gaussian-noise assumption is widely adopted in the study of qubit decoherence, non-Gaussian noise sources, especially the strong discrete fluctuators, have been detect…
Stabilizing and improving qubit coherence by engineering noise spectrum of two-level systems
Xinyuan You, Ziwen Huang, Ugur Alyanak +3
Superconducting circuits are a leading platform for quantum computing. However, their coherence times are still limited and exhibit temporal fluctuations. Those phenomena are often…
