QMIMO: Circuit Based Quantum MIMO Design with Variational Receiver
Sayeda Bipanchi Ahmed, Bikash K. Behera, Mandar Thatte +1
This paper investigates a quantum extension of classical Multiple-Input Multiple-Output (MIMO) communication in which the conventional linear channel model is replaced by a paramet…
Unsharp Measurement with Adaptive Gaussian POVMs for Quantum-Inspired Image Processing
Debashis Saikia, Bikash K. Behera, Mayukha Pal +1
We propose a data-adaptive probabilistic intensity remapping framework for structure-preserving transformation of grayscale images. The suggested method formulates intensity transf…
Quantum Simulation and Energy Estimation for Discretized Anharmonic oscillator
Saurav Suman, Bikash K. Behera, Vivek Vyas +1
Anharmonic potential quantum system play crucial role in physics as they provide a more realistic description of oscillatory phenomena, which often deviate from the idealized harmo…
Excitation Gaps of Ground and Excited State Energy of the Fermi-Hubbard Model Using Variational Quantum Eigensolver
Mrinal Dev, Bikash K. Behera, Vivek Vyas +1
The Hubbard model is a challenging quantum many-body problem and serves as a benchmark for quantum computing research. Accurate computation of its ground and excited state energies…
Evolution of Entanglement Witness of Dicke State under Noise and Error Mitigation
Tomis Prajapati, Harsh Mehta, Shreya Banerjee +2
The experimental verification of multipartite entangled states is essential for advancing quantum information processing. Entanglement witnesses (EWs) provide a widely used and exp…
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…
