Superconducting quantum computing is a branch of quantum computing and solid-state physics that implements superconducting electronic circuits as qubits in a quantum processor. These devices are typic
A laboratory team assembles a cryogenic part of a superconducting quantum computer. This provides necessary cooling of superconducting processors to almost absolute zero (-273.1°C).
John M. Martinis, the 2025 Nobel laureate in physics, led the team at Google Quantum AI that built the Sycamore processor, which, in 2019, claimed the first evidence of quantum supremacy.
In a superconductor, weakly paired electrons (red) known as Cooper pairs, can avoid disturbances when moving through the lattice.
Fabrication of superconducting circuits takes place inside of a highly controlled cleanroom.
