Coherence thermometry using multipartite quantum systems
Pranav Perumalsamy, Abhijit Mandal, Sovik Roy +1
Accurate temperature measurement at the quantum scale is becoming increasingly important for emerging quantum technologies, motivating the development of quantum thermometry based…
Near-perfect Noisy Quantum State Teleportation
Md Manirul Ali, Sovik Roy, Dipankar Home
Achieving high fidelity of quantum teleportation (QT) in a noisy environment is an essential requirement for its real-world applications. To this end, we devise a distinctive proto…
Non-maximally entangled mixed states of X and non-X types as teleportation channels
Anushree Pandey, Sovik Roy, Md. Manirul Ali +1
Mixed spin-1/2 states violating Bell-CHSH inequality is useful for teleportation. There exist states which do not violate Bell-inequality but is still useful as teleportation chann…
Dephasing-Induced Distribution of Entanglement in Tripartite Quantum Systems
Sovik Roy, Md. Manirul Ali, Abhijit Mandal +1
Preserving multipartite entanglement amidst decoherence poses a pivotal challenge in quantum information processing. However, assessing multipartite entanglement in mixed states am…
