Why superconducting qubits need periodic calibration?

Why superconducting qubits need periodic calibration? Ask Question Asked 2 years, 4 months ago Modified 4 days ago Viewed 137 times 3 I want to understand in some detail why superconducting qubits need periodic calibration. The usual, hand wavy explanation is environmental effects that tend to vary. However, I suspect that the actual picture is more complex than that. I want to understand in particular which effects are purely external, like the earth magnetic field (in lack of a better example) and which are internal to the superconducting device. I am especially interested in those factors that are internal to the qubit itself, like manufacturing defects and physical characteristics that may change in time. A good reference on this subject would be appreciated. superconducting-quantum-computing Share Improve this question Follow asked Nov 8, 2023 at 15:52 Radu M. 2601 1 silver badge 10 10 bronze badges Add a comment 1 Answer Sorted by: Highest score (default) Date modified (newest first) Date created (oldest first) 0 In terms of a good reference, I found this helpful when researching this topic: arXiv. sc qubits are famously error-prone (hence why we are still seeking fault tolerance), and as you stated, there are concerns with both environmental factors and physical factors. A brief list I compiled from the aforementioned article is as follows: Environmental Factors Magnetic fields Temperature fluctuations Electrical interference (i.e. vibrations from other lab equipment, other noise) Physical Factors Material aging (resulting in defects which grow in size). I could not find evidence of significant research as it relates to sc qubits in particular* Charge traps and impurities: Atomic-scale imperfections can randomly shift, trapping or releasing electrons and causing sudden jumps in qubit behavior.
