Quantum detection of wormholes.

Area of Science:

• Quantum physics
• Astrophysics
• General relativity

Background:

• Wormholes are hypothetical topological features that could connect distant points in spacetime.
• Detecting wormholes is challenging due to their potential distance and the weak gravitational effects they might produce.

Purpose of the Study:

• To propose a novel method for detecting wormholes using quantum metrology.
• To investigate the feasibility of detecting wormholes with current and near-future experimental capabilities.

Main Methods:

• Utilizing coherent states of the electromagnetic field.
• Analyzing phase shifts induced by wormhole throat radius.
• Employing homodyne measurements for detection.
• Simulating realistic parameters from long-baseline laser interferometry.

Main Results:

• A slight phase shift in the electromagnetic field is dependent on the wormhole's throat radius.
• This phase shift is detectable even over long propagation distances and far from the wormhole.
• The detection scheme is robust against optical losses and initial mixedness of the quantum state.

Conclusions:

• Quantum metrology offers a viable pathway for detecting distant wormholes.
• The proposed method is experimentally achievable with state-of-the-art laser interferometry.
• This work opens new avenues for observational tests of general relativity and exotic objects.
