Abstract
Limitations in coherence time and gate fidelity are among the most significant obstacles to scaling superconducting quantum computers, both of which are influenced by system noise sources. To control noise, one must first recognize the noise sources in superconducting qubits and then address methods to manage them. The main noise sources in superconducting qubits include charge noise, flux noise, thermal noise, photon number fluctuations, and noise caused by quasiparticles. Control methods include improving superconducting materials, enhancing superconducting chip fabrication techniques, cooling, noise filtering, quantum error correction, and more resilient qubit design and engineering.
