In situ characterization of a photon-subtraction device via heralding counts and homodyne detection
Priyanka Sharma, Matteo G. A. Paris, Stefano Olivares
Photon subtraction is one of the most important techniques for generating non-Gaussian optical states and constitutes a key resource for quantum information processing and quantum…
Mitigating sloppiness in joint estimation of successive squeezing parameters
Priyanka Sharma, Stefano Olivares, Devendra Kumar Mishra +1
When two successive squeezing operations with the same phase are applied to a field mode, reliably estimating the amplitude of each is impossible because the output state depends s…
Enhancement in phase sensitivity of SU(1,1) interferometer with Kerr state seeding
Priyanka Sharma, Aviral K. Pandey, Gaurav Shukla +1
A coherent seeded SU(1,1) interferometer provides a prominent technique in the field of precision measurement. We theoretically study the phase sensitivity of SU(1,1) interferomete…
Super-resolution and super-sensitivity of quantum LiDAR with multi-photonic state and binary outcome photon counting measurement
Priyanka Sharma, Manoj K. Mishra, Devendra Kumar Mishra
Here we are investigating the enhancement in phase sensitivity and resolution in Mach-Zehnder interferometer (MZI) based quantum LiDAR. We are using multi-photonic state (MPS), sup…
Quantum-enhanced super-sensitivity of Mach-Zehnder interferometer using squeezed Kerr state
Dhiraj Yadav, Gaurav Shukla, Priyanka Sharma +1
We study the phase super-sensitivity of a Mach-Zehnder interferometer (MZI) with the squeezed Kerr and coherent states as the inputs. We discuss the lower bound in phase sensitivit…
