Quantum weak-value birefringent Coriolis vibratory gyroscope

A device for measurement of rotation rate, said device comprising:

• a vertical-cavity surface-emitting laser for emitting an optical beam of photons along a drive axis orthogonal to rotation and sense axes;
• a first polarizer for pre-selection of said optical beam into equal superposition of pre-selection polarization states in horizontal and vertical planes;
• a birefringent crystal composed of uniaxial mineral crystal silicon dioxide for weakly interacting with and splitting said optical beam of photons into a mutually in-phase pair of parallel beams of photons that emerges from said birefringent crystal along said drive axis and separated along said sense axis, said optical beam intersecting said birefringent crystal at an incidence angle;
• a second polarizer for post-selection of said pair of parallel beams into post-selection polarization states nearly orthogonal to said pre-selection polarization states;
• a detector for registering said parallel beams of photons;
• and
• a platform onto which said laser, said first polarizer, said crystal, said second polarizer and said detector are sequentially disposed parallel to said vertical plane, wherein
• said parallel beams are distinguished by horizontal and vertical polarizations relative to said birefringent crystal, and separate by phase difference in response to the rotation rate about said rotation axis, and
• said birefringent crystal weakly interacts with said optical beam to amplify said phase difference.
