About Superconducting Technology
Superconducting qubits are electrical circuits cooled to millikelvin temperatures where quantum effects dominate. They are fabricated using standard semiconductor lithography, making them highly scalable. Qubits are formed from Josephson junctions — non-linear inductors that create discrete energy levels. IBM, Google, and Rigetti lead commercial deployment of this technology.
Fast gate speeds (tens to hundreds of nanoseconds), mature fabrication technology using standard semiconductor processes, and strong industry investment make this the most commercially advanced platform.
Requires dilution refrigerators operating near absolute zero (~15 mK), leading to large physical footprints and high infrastructure costs. Qubits are sensitive to noise, limiting coherence times to microseconds-to-milliseconds range.
