6 Copyright © D-Wave First-Ever Qubits Japan Conference in Tokyo Held first-ever Qubits Japan Quantum Computing User Conference in Tokyo on September 17, 2025 Presenters included: • Dr. Alan Baratz and Dr. Trevor Lanting of D-Wave • Hidetoshi Nishimori, professor emeritus at the Institute of Science Tokyo and widely considered the father of quantum annealing • Representatives of several of D-Wave’s customers including Japan Tobacco, NTT DOCOMO and Tohoku University

7 Copyright © D-Wave Superconducting's Advantages Over Other Quantum Approaches • Superconducting approaches have best gate speed vs. fidelity tradeoff • Superconducting approaches can leverage semiconducting CMOS manufacturing technology for scalability • Trapped ion and neutral atom approaches are more than 1,000- 10,000x slower in algorithm execution time • There is no manufacturing base to support scaling trapped ion and neutral atom approaches: needs fundamental breakthroughs and massive investment • Trapped ion approaches have failed to scale beyond a few dozen ions in a trap: ion addressability, magnetic field control, and integrated photonics are all major technical challenges to scaling • Photonic approaches require fundamentally new manufacturing techniques to build photonic integrated circuits and high fidelity photon detectors: will need massive investment

8 Copyright © D-Wave Progress with Gate-Model Program: Completed Fabrication of Fluxonium Qubit Chips and Superconducting Control Chips • Completed the fabrication of fluxonium qubit chips and superconducting control chips and are currently integrating the two to demonstrate scalable control of gate model qubits • D-Wave believes this work will enable the first-ever scalable gate model system with cryogenic control Advantage2 QPU Mounted in D-Wave's Proprietary Cryogenic Packaging
