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…
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 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…
A tomographic approach to the sum uncertainty relation and quantum entanglement in continuous variable systems
Soumyabrata Paul, S. Lakshmibala, V. Balakrishnan +1
Entropic uncertainty relations (EURs) have been examined in various contexts, primarily in qubit systems, including their links with entanglement, as they subsume the Heisenberg un…
Manifestations of changes in entanglement and onset of synchronization in tomograms
Soumyabrata Paul, S. Lakshmibala, V. Balakrishnan +1
Quantum state reconstruction for continuous-variable systems such as the radiation field poses challenges which arise primarily from the large dimensionality of the Hilbert space.…
Quantum fluctuations stabilize an inverted pendulum
Rohit Chawla, Soumyabrata Paul, Jayanta K. Bhattacharjee
We explore analytically the quantum dynamics of a point mass pendulum using the Heisenberg equation of motion. Choosing as variables the mean position of the pendulum, a suitably d…
From periodically driven double wells to volcano potentials: Quantum dynamics
Soumyabrata Paul, Rohit Chawla, Mandira Das +1
We consider the dynamics of a particle confined in a double well potential which is subjected to a periodic drive. In the case of deep and well separated wells, we find that by adj…
