A machine learning approach to tomographic pattern generation and classification of quantum states of light
Soumyabrata Paul, H. S. Subramania, S. Ramanan +2
Optical tomograms can be envisaged as patterns. The Wasserstein generative adversarial network (WGAN) algorithm provides a platform to train the machine to compare patterns corresp…
Tomographic markers and photon addition to coherent states of light: Comparison with experiment
Soumyabrata Paul, S. Lakshmibala, V. Balakrishnan +1
Photon addition to quantized light is of immense interest, both experimentally and theoretically. We identify a set of markers that play an important role in the context of photon…
Comparing probability distributions: application to quantum states of light
Soumyabrata Paul, V. Balakrishnan, S. Ramanan +1
Probability distributions play a central role in quantum mechanics, and even more so in quantum optics with its rich diversity of theoretically conceivable and experimentally acces…
Optimal sensing of photon addition and subtraction on nonclassical light
Soumyabrata Paul, Arman, S. Lakshmibala +3
We demonstrate that the Wasserstein distance corresponding to optical tomograms of nonclassical states faithfully captures changes that arise due to photon addition to, or…
Tomographic entanglement indicators in a coupled oscillator model
Sreelekshmi Pillai, S. Ramanan, V. Balakrishnan +1
We study entanglement in a simple model comprising two coupled linear harmonic oscillators of the same natural frequency. The system is separable in the center of mass (COM) and re…
