Quantum Optical Noise and Interferometry Evaluator

IXO needs analyses that connect quantum-optical algebra to measurable behavior. Assignments examine cascaded parametric amplifiers and interferometric systems, with particular attention to whether noise, loss and correlations have been modeled consistently.

Work you will do

• Model cascaded optical parametric amplifiers and SU(1,1) interferometers under realistic loss assumptions.
• Use Bogoliubov transformations and covariance matrices to assess quantum correlations and noise.
• Derive or review sideband photocurrent spectra for homodyne detection, checking the interpretation of the measured quantities.
• Inspect fictitious-beamsplitter loss models and apply hyperbolic squeeze-parameter identities to analyze entanglement and two-mode squeezing.

Preferred background

• PhD or equivalent experience in AMO physics, quantum optics or quantum-information science.
• Practical command of Bogoliubov transformations, covariance methods and quantum-noise calculations.
• Hands-on familiarity with homodyne sidebands and optical-loss models, and demonstrated use of squeeze-parameter identities.
• Frontier research on cascaded parametric amplifiers, SU(1,1) interferometry or two-mode squeezing.

Deliverables

A documented solution, audit or adjudication with assumptions, derived quantities, checks and defensible physical interpretation.
