Which-crystal information and wave-particle duality in induced-coherence interferometry
L. Theerthagiri
We provide an operational reinterpretation of wave-particle complementarity in the low-gain Zou-Wang-Mandel (ZWM) induced-coherence interferometer. In the low gain limit, each phot…
Measuring dark state number in the Tavis-Cummings model
L. Theerthagiri, Rajesh Narayanan, R. Ganesh
Quantum mechanics allows for light-matter setups that hold excitations without releasing them as light. Arising from destructive interference processes, they are best seen in a Tav…
Spreading entanglement through pairwise exchange interactions
L. Theerthagiri, R. Ganesh
The spread of entanglement is a problem of great interest. It is particularly relevant to quantum state synthesis, where an initial direct-product state is sought to be converted i…
Resonating valence bonds and spinon pairing in the Dicke model
R. Ganesh, L. Theerthagiri, G. Baskaran
Resonating valence bond (RVB) states are a class of entangled quantum many body wavefunctions with great significance in condensed matter physics. We propose a scheme to synthesize…
