Super-Sensitive Quantum Metrology with Separable States
Mayukh Lahiri, Manuel Erhard
We introduce a super-sensitive phase measurement technique that yields the Heisenberg limit without using either a squeezed state or a many-particle entangled state. Instead, we us…

Many-Particle Interferometry and Entanglement by Path Identity
Mayukh Lahiri
We introduce a general scheme of many-particle interferometry in which two identical sources are used and "which-way information" is eliminated by making the paths of one or more p…

Effects of Refraction and Reflection on Coherence Properties of Light
Mayukh Lahiri, Emil Wolf
Partially coherent light beams are encountered both in classical and in quantum optics. Their coherence properties generally depend on the correlation properties of their sources.…
