Verification of continuous variable entanglement with undetected photons
Sanjukta Kundu, Balakrishnan Viswanathan, Pawel Szczypkowski +3
We verify transverse spatial entanglement of photon-pairs generated in spontaneous parametric down conversion using a nonlinear interferometric technique without relying on any coi…
High-dimensional quantum correlation measurements with an adaptively gated hybrid single-photon camera
Sanjukta Kundu, Jerzy Szuniewicz, Grzegorz Firlik +2
Efficient measurement of high-dimensional quantum correlations, especially spatial ones, is essential for quantum technologies, given their inherent high dimensionality and easy ma…
Self-referenced hologram of a single photon beam
Wiktor Szadowiak, Sanjukta Kundu, Jerzy Szuniewicz +1
Quantitative characterization of the spatial structure of single photons is essential for free-space quantum communication and quantum imaging. We introduce an interferometric tech…
