Studying fermionic ghost imaging with independent photons.

Area of Science:

• Quantum optics
• Quantum information science
• Statistical mechanics

Background:

• Ghost imaging is a technique that utilizes correlations between two light beams to form an image.
• Fermionic systems present unique challenges for quantum imaging due to their antisymmetric wave function.

Purpose of the Study:

• To theoretically calculate and experimentally investigate ghost imaging with thermal fermions.
• To explore the feasibility of simulating fermionic ghost imaging using more accessible systems.

Main Methods:

• Utilized Feynman's path integral theory and the superposition principle for two-particle interference calculations.
• Employed photons in pseudothermal light to experimentally simulate fermionic ghost imaging.
• Analyzed point-to-point (spot) correlations between object and image planes.

Main Results:

• Demonstrated that ghost imaging with fully polarized thermal fermions can be simulated by ghost imaging with fully polarized thermal bosons and classical particles.
• Provided experimental validation using pseudothermal light.

Conclusions:

• The proposed method offers an efficient approach for future ghost imaging experiments with real thermal fermions.
• The technique may be generalized to study other second-order interference phenomena involving fermions.
