100 Quantum Computing Companies Shaping the Global Quantum Revolution (2025)
Google Quantum AI achieved quantum supremacy in 2019 with the 54-qubit Sycamore processor performing a random circuit sampling task in 200 seconds. IBM Quantum progressed from the 127-qubit Eagle milestone in 2021 to 433-qubit Osprey in 2022, with a plan for a 1,121-qubit Condor and a long-term goal of about one million physical qubits by the decade’s end. D-Wave Systems, founded in 1999, sells the Advantage quantum annealing system with over 5,000 qubits and went public in 2022. Xanadu’s Borealis photonic processor demonstrated in 2022 uses 216 squeezed modes to perform Gaussian boson sampling with 125 million samples in 36
