Summary
👤
Senior🎓
Top SchoolJohn Long is a scientific software engineer specializing in quantum and classical computing with eight years of experience building tooling for national labs, defense contractors, and startups. He has shipped production components for neutral-atom compilers and analog Hamiltonian emulators at QuEra, and previously developed Boson Sampling utilities, QUBO generators for quantum annealers, and photonic chip job systems at Iff Technologies. His background spans systems engineering and automation—Kubernetes testbeds at Sandia, network deployment tools at Intel, and SDR tooling at General Dynamics—giving him a pragmatic, production-focused approach to research code. John also designs and teaches collegiate quantum workshops, turning abstract quantum concepts into intuitive, hands-on curricula. Based in Boston, he contributes to open-source quantum simulation (Bloqade.jl) and blends low-level performance work (multithreading, ODE solvers) with hardware telemetry and direct-to-QPU execution. He’s equally comfortable explaining quantum advantage to students as he is optimizing compiler stacks for error-corrected experiments.
