Beating noise in frequency estimation with squeezing and memory in continuous-variable systems
Ayan Patra, Manju, Aditi Sen De +1
Quantum metrology promises precision beyond classical limits, yet environmental noise typically degrades the quantum resources required for such enhancement. In this work, we inves…
Quantum synchronization between two spin chains using pseudo-bosonic equivalence
Jatin Ghildiyal, Manju, Shubhrangshu Dasgupta +1
Quantum synchronization among many spins is an intriguing domain of research. In this paper, we explore the quantum synchronization of two finite chains of spin-1/2 particles, via…
Quantum synchronization and entanglement of indirectly coupled mechanical oscillators in cavity optomechanics: a numerical study
Devender Garg, Manju, Shubhrangshu Dasgupta +1
It is often conjectured that quantum synchronisation and entanglement are two independent properties which two coupled quantum systems may not exhibit at the same time. However, as…
Entanglement as a sufficient condition for quantum synchronization between two mechanical oscillators
Manju, Shubhrangshu Dasgupta, Asoka Biswas
We present an optomechanical model to show that entanglement can be a sufficient condition for quantum synchronization of two mechanical oscillators. As both these entities can be…
