High-dimensional quantum process tomography with undetected photons
Salini Rajeev, Mayukh Lahiri
The goal of quantum process tomography is to fully characterize an operation performed on a quantum state. By considering high-dimensional quantum states (qudit), we show that it i…

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…
