Superconducting Microresonator Signal Denoising Using Machine Learning

Superconducting microresonators are pivotal in the realm of quantum computing, essential for establishing superpositions. As quantum technology evolves, these components become even more integral, not just in quantum applications but also as precision instruments in astronomy—specifically as highly sensitive cameras. Microwave kinetic inductance detectors are notable in this field, recognized for their heightened sensitivity crucial for both scientific exploration and industrial use. Yet, electronic noise remains a formidable obstacle. Addressing this, our approach combines machine learning strategies with traditional noise reduction techniques to enhance the signal clarity of superconducting microresonators. Our process involves gathering data and applying various denoising models, placing a significant emphasis on machine learning methods. We have discovered that certain denoising approaches, especially deep learning frameworks such as long short-term memory networks and autoencoders, are highly effective in clarifying the signals from superconducting microresonators. These models demonstrate versatility in handling different noise types, skill in deciphering intricate noise structures, and they consistently improve their performance as more data is provided.
