Role Title: Physics Expert (Condensed Matter / Quantum Information)

Role Type: Contractor

Location: Remote

We are engaging Physics Experts (Condensed Matter / Quantum Information) to contribute to a frontier research-level physics benchmark project focused on topics such as the PXP model, Rydberg blockade, quantum many-body scars, and constrained dynamics. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.

Scope of Work

1. Develop and analyze exact diagonalization implementations leveraging translation and reflection symmetries, with a preference for QuSpin and system sizes L ≥ 26.
2. Construct and manipulate block-diagonalized subspaces for complex quantum systems, optimizing computational efficiency and fidelity.
3. Evaluate overlaps with Z2 states and interpret resulting physical insights in the context of constrained quantum dynamics.
4. Contribute detailed written feedback, analytic reports, and assessments for research benchmarks related to quantum many-body scars and Rydberg blockade phenomena.
5. Serve as a Solver, Auditor, or Adjudicator on the project, depending on subfield alignment, hands-on methods expertise, and seniority.

Preferred Qualifications

1. Advanced academic background (PhD or equivalent practical experience) in condensed matter physics, quantum information, or a closely related field.
2. Proven expertise in exact diagonalization techniques, including experience with QuSpin and symmetries for large system sizes.
3. Demonstrated ability to perform block-diagonalization of Hamiltonians and work within large Hilbert space subspaces.
4. Strong understanding of quantum many-body scars, Rydberg blockade, and constrained quantum dynamics.
5. Experience analyzing overlaps with Z2 or related quantum states, including the interpretation of numerical results.
