Quantum-Enhanced Single-Parameter Phase Estimation with Adaptive NOON States

Simanshu Kumar, Nandan S Bisht

Quantum metrology promises phase sensitivity surpassing the shot-noise limit by exploiting entanglement and photon-number correlations. NOON states-maximally path-entangled -pho…

OAM-Induced Lattice Rotation Reveals a Fractional Optimum in Fault-Tolerant GKP Quantum Sensing

Simanshu Kumar, Nandan S Bisht

Photon loss and dephasing rapidly degrade the sensitivity of quantum sensors, yet systematic methods for designing error-correcting codes whose geometry is simultaneously adapted t…

Extended depth of field of diffraction limited imaging system using spatial light modulator based intensity compensated polarization coded aperture

Vipin Tiwari, Nandan S. Bisht

Reducing the aperture size is a conventional technique to obtain enhanced image resolution in optics but it is obscured by depleting illumination. Polarization coded apertures (PCA…

Ghost diffraction: A spatial statistical approach

Manisha, Vipin Tiwari, Nandan S Bisht +2

We report the reconstruction of a transparency image in Ghost diffraction scheme using a statistical optics approach. This is implemented by using a static diffuser rather than a p…
