From triangles to prisms: towards a geometric extension of concurrence fill for three-qubit mixed states
Divyanshu K. Verma, Girish Kulkarni
The quantification of multipartite entanglement remains a long-standing open challenge in quantum information theory with major implications for quantum foundations and quantum tec…
Full-field mapping of spatially varying polarization entanglement generated from spontaneous parametric down-conversion
Cheng Li, Girish Kulkarni, Isaac Soward +6
Two-photon states generated from spontaneous parametric down-conversion (SPDC) can display entanglement in all degrees of freedom (DoFs) of light, including spatial, temporal, and…
Theory of temporal three-photon interference
Nilakshi Senapati, Girish Kulkarni, Anand K. Jha
The recent demonstrations of cascaded PDC (CPDC) and the hopeful prospects of realizing third-order PDC (TOPDC) for the generation of three-photon entangled states are paving the w…
Full Schmidt characterization of spatiotemporally entangled states produced from spontaneous parametric down-conversion
Rakesh Pradhan, Girish Kulkarni
The full Schmidt decomposition of spatiotemporally entangled states generated from spontaneous parametric down-conversion (SPDC) has not been carried out until now due to the immen…
Efficient characterization of spatial Schmidt modes of multiphoton entangled states produced from high-gain parametric down-conversion
Mahtab Amooei, Girish Kulkarni, Jeremy Upham +1
The ability to efficiently characterize the spatial correlations of entangled states of light is critical for applications of many quantum technologies such as quantum imaging. Her…
