Remote | Physics Expert (AMO / Quantum Information) — $80–$160/hour

We are sharing a specialised consulting opportunity for experienced Physics Experts in Atomic, Molecular, and Optical Physics, Quantum Optics, and Quantum Information with strong expertise in Bogoliubov transformations, covariance-matrix methods, homodyne detection, quantum-noise analysis, sideband photocurrent spectra, and lossy quantum optical systems.

Selected professionals will contribute to a frontier research-level benchmarking project involving cascaded optical parametric amplifiers, SU(1,1) interferometers, two-mode squeezing, and realistic loss mechanisms. Contributors may participate as Solvers, Auditors, or Adjudicators depending on subfield expertise, research experience, and hands-on familiarity with the required methods. No prior experience in AI is required.

Solver, Auditor & Adjudicator Responsibilities

• Serve as a Solver by independently deriving technically rigorous solutions
• Serve as an Auditor by checking calculations, assumptions, and physical interpretations
• Serve as an Adjudicator where competing approaches require expert comparison
• Document reasoning clearly and defensibly
• Adapt project responsibilities according to subfield expertise and seniority

Ideal Profile
