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 Computing of Phonon Spectra and Thermal Properties of Crystalline Solids
Naman Khandelwal, Bikash K. Behera, Ashok Kumar +1
Variational quantum algorithms offer a promising framework for solving eigenvalue problems on near-term quantum hardware, yet their applicability beyond electronic structure calcul…
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…
Discerning and quantifying high frequency activities in EEG under normal and epileptic conditions
Jyotiraj Nath, Shreya Banerjee, Bhaswati Singha Deo +2
We investigate the nature of the modifications in the temporal dynamics manifested in the high-frequency EEG spectra of the normal human brain in comparison to the diseased brain u…
