Computable genuine multimode entanglement measure: Gaussian vs. non-Gaussian
Saptarshi Roy, Tamoghna Das, Aditi Sen De
Genuine multimode entanglement in continuous variable systems can be quantified by exploring the geometry of the state-space, namely via the generalized geometric measure (GGM) whi…
Uniform Decoherence Effect on Localizable Entanglement in Random Multi-qubit Pure States
Ratul Banerjee, Amit Kumar Pal, Aditi Sen De
We investigate the patterns in distributions of localizable entanglement over a pair of qubits for random multi-qubit pure states. We observe that the mean of localizable entanglem…
Enhancement in performance of quantum battery by ordered and disordered interactions
Srijon Ghosh, Titas Chanda, Aditi Sen De
Considering ground state of a quantum spin model as the initial state of the quantum battery, we show that both ordered and disordered interaction strengths play a crucial role to…
Recycling the resource: Sequential usage of shared state in quantum teleportation with weak measurements
Saptarshi Roy, Anindita Bera, Shiladitya Mal +2
Complete measurements, while providing maximal information gain, results in destruction of the shared entanglement. In the standard teleportation scheme, the sender's measurement o…
Frequentist-approach inspired theory of quantum random phenomena predicts signaling
C. S. Sudheer Kumar, Anup Biswas, Aditi Sen De +1
Different ensembles of the same density matrix are indistinguishable within the modern Kolmogorov probability measure theory of quantum random phenomena. We find that changing the…
