Post-Selection-Based Stochastic Quantum Battery
Aman Verma, Roson Nongthombam, Amarendra K. Sarma
Quantum batteries are quantum systems that store useful energy, which can be subsequently extracted to perform work. In this paper, we investigate the charging dynamics of the quan…
Robust Nonclassical magnon pair generation and Cauchy-Schwarz inequality violation in a hybrid electromagnonic system
Sabur A Barbhuiya, Ajeet Kumar, Amarendra K Sarma
Magnonic systems are a promising resource for quantum technologies because of their ability to couple significantly disparate quantum platforms and the generation of nonclassical m…
Nonlocal Magnonic Cat States in Hybrid Magnon-Qubit Architectures
Urmimala Dewan, Roson Nongthombam, Sampreet Kalita +1
The quantum superpositions of coherent states offer an alternative to the conventional qubit-based encodings by harnessing the large Hilbert space available in bosonic modes, inclu…
Fundamentals and Applications of Hybrid Electro- and Opto-mechanical system coupled to Superconducting Qubit: A Short Review
Roson Nongthombam, Urmimala Dewan, Amarendra K. Sarma
Superconducting qubits, realized by incorporating Josephson junctions into superconducting circuits, behave as artificial atoms with anharmonic energy spectra and can be precisely…
Entanglement Dynamics in a Two Transmon Qubit System under Continuous Measurement and Postselection
Roson Nongthombam, Amarendra K. Sarma
We investigate the role of continuous measurement and postselection in the dynamics and entanglement of a transmon-cavity-transmon coupled system. In the dispersive regime, charact…
Quantum Noise Suppression Beyond the Standard Quantum Limit in a Hybrid Magnonic Optomechanical System
Alolika Roy, Amarendra K. Sarma
We theoretically study how quantum measurement noise can be engineered in a hybrid cavitymagnomechanical platform for precision force sensing. The proposed configuration consists o…
