[Hiring] Physics Expert (Condensed Matter / Quantum Information) @Xperteez Technology

Role Description

Physics Expert (Condensed Matter / Quantum Information) - Contractor, Remote

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

Qualifications

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

Requirements

• Physics
• Exact diagonalization with translation + reflection symmetries (QuSpin preferred) for L >= 26
• Subspace block-diagonalization
• Overlap with Z2 state analysis
