Quadratic power enhancement in extended Dicke quantum battery
Harsh Sharma, Himadri Shekhar Dhar
We demonstrate a quadratic enhancement of power in a battery consisting of two-level systems or spins interacting with two photonic cavity modes, where one of the modes is in t…
Thermodynamic Probes of Multipartite Entanglement in Strongly Interacting Quantum Systems
Harsh Sharma, Sampriti Saha, A. S. Majumdar +2
Quantifying multipartite entanglement in quantum many-body systems and hybrid quantum computing architectures is a fundamental yet challenging task. In recent years, thermodynamic…
Quantum error correction for an unresolvable spin ensemble
Harsh Sharma, Himadri Shekhar Dhar, Hoi-Kwan Lau
Spin ensembles are promising quantum technological platforms, but their utility relies on the ability to perform quantum error correction (QEC) for the specific decoherence in thes…
Improving Performance of Quantum Heat Engines using modified Otto cycle
Revathy B. S, Harsh Sharma, Uma Divakaran
The efficiency of a quantum heat engine is maximum when the unitary strokes are adiabatic. On the other hand, this may not be always possible due to small energy gaps in the system…
Protecting information in a parametrically driven hybrid quantum system
Siddharth Tiwary, Harsh Sharma, Himadri Shekhar Dhar
The transfer and storage of quantum information in a hybrid quantum system, consisting of an ensemble of atoms or spins interacting with a cavity, is adversely affected by the inho…
