Enhancing Measurement Precision of Non-Degenerate Two-Photon Absorption
Gaurav Shukla, Shahram Panahiyan, Devendra Kumar Mishra +1
Recent theoretical and experimental studies have shown that squeezed states of light can be engineered to enhance the resolution of nonlinear optical measurements. Here, we analyze…
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…
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…
Broadening the high sensitivity range of squeezing-assisted interferometers by means of two-channel detection
Gaurav Shukla, Dariya Salykina, Gaetano Frascella +3
For a squeezing-enhanced SU(2) interferometer, we theoretically investigate the possibility to broaden the phase range of sub-shot-noise sensitivity. We show that this goal can be…
