Pure two-qubit states carried by single-photons: unrestricted generation and entanglement diagnosis by single-qubit tomography
Abstract
The primary focus of this effort is to address foundational questions related to the boundary between classical and quantum mechanics. The PI proposes to implement and test two all-optical schemes, allowing unrestricted generation of pure two-qubit states with single photons as physical carriers. These states may be characterized using polarization tomography and interferometric measurement of the optical path. The degree of state entanglement would be determined using a recently established relationship between degree of polarization and concurrence. The approach is sound and the PI s team already conducted preliminary experiments with coherent light to reduce risk. The PI is aware of the state of the art and his innovative research idea actually preceded the release of the ONR MURI solicitation, in which Topic #2 addresses classical entanglement of light and would complement the proposed effort. The PI and his team have the needed theoretical and experimental quantum optics expertise and facilities to be successful and are well published in the field.
