ABOUT SITAKANTA SATAPATHY

I’m a Senior Principal Process Integration Engineer at D-Wave Quantum specializing in superconducting quantum hardware, QPU fabrication, and wafer-scale process development. My work focuses on Josephson junction fabrication, lithography process optimization, materials integration, and advanced device characterization for high-coherence superconducting qubits.IMPACT AT A GLANCE- 10× yield improvement in superconducting quantum devices through process and materials optimization- 4-inch wafer-scale fabrication of quantum devices and QPU components-~90% Josephson junction target accuracy across full 4-inch wafers- Consistent on-time delivery in fast-paced quantum R&D and production environments- ESD-critical fabrication workflows for ultra-sensitive quantum hardwareCORE EXPERTISE- Quantum Hardware Engineering | Superconducting Qubits | QPU Fabrication- Josephson Junctions | Thin-Film Deposition | Etching | Lift-off- Nanofabrication | Microfabrication | Wafer-Scale Manufacturing- Electron-Beam Lithography (EBL)| Optical Lithography- Resist Chemistry | Developer Chemistry | Process Control- Device Yield Optimization | Process Integration | Metrology- SEM | AFM | Profilometry | Electrical Characterization- ESD-Safe Processing | Cleanroom Operations- Photonic & Optoelectronic Devices | Materials ScienceDuring my postdoc, I developed a record-setting, universal framework for room-temperature polariton quantum condensation, later realized as the world’s first scalable ultra-low-threshold 2D lattice. This work established deep expertise in quantum coherence, light–matter interaction, and nanoscale device engineering, now applied to superconducting quantum hardware. I operate across R&D, pilot manufacturing, and cross-functional teams to translate quantum physics into scalable, manufacturable platforms.Earlier in my career, I worked on photochemistry, supramolecular assemblies, polymer self-assembly, optoelectronic and energy-storage materials, giving me a rare cross-disciplinary foundation spanning chemistry, materials science, and quantum engineering.
