In-Line Fiber-Integrated Photon-Pair Generation from van der Waals Crystals
Mayank Joshi, Tanumoy Pramanik, Mengting Jiang +9
Miniaturized quantum light sources that operate directly in optical fibers are an attractive platform for optical quantum technologies. However, most miniaturized spontaneous param…
Physical interpretation of nonlocal quantum correlation through local description of subsystems
Tanumoy Pramanik, Xiaojiong Chen, Yu Xiang +11
Characterization and categorization of quantum correlations are both fundamentally and practically important in quantum information science. Although quantum correlations such as n…

Xiaojiong Chen, Yaohao Deng, Shuheng Liu +15
Famous double-slit or double-path experiments, implemented in a Young's or Mach-Zehnder interferometer, have confirmed the dual nature of quantum matter, When a stream of photons,…
Entangling three identical particles via spatial overlap
Donghwa Lee, Tanumoy Pramanik, Young-Wook Cho +3
Quantum correlations between identical particles are at the heart of quantum technologies. Several studies with two identical particles have shown that the spatial overlap and indi…
Entangling Bosons through Particle Indistinguishability and Spatial Overlap
Mariana R. Barros, Seungbeom Chin, Tanumoy Pramanik +4
Particle identity and entanglement are two fundamental quantum properties that work as major resources for various quantum information tasks. However, it is still a challenging pro…
Nonlocal quantum correlations under amplitude damping decoherence
Tanumoy Pramanik, Young-Wook Cho, Sang-Wook Han +3
Different nonlocal quantum correlations of entanglement, steering and Bell nonlocality are defined with the help of local hidden state (LHS) and local hidden variable (LHV) models.…
Experimental comparison of various quantum key distribution protocols under reference frame rotation and fuctuation
Juhwan Yoon, Tanumoy Pramanik, Byung Kwon Park +4
In free-space quantum key distribution (QKD) between moving parties, e.g., free-space QKD via satellite, the reference frame rotation and fluctuation degrades the performance of QK…
Informationally symmetrical Bell state preparation and measurement
Yong-Su Kim, Tanumoy Pramanik, Young-Wook Cho +4
Bell state measurement (BSM) plays crucial roles in photonic quantum information processing. The standard linear optical BSM is based on Hong-Ou-Mandel interference where two photo…

Souradeep Sasmal, Tanumoy Pramanik, Dipankar Home +1
We consider quantum steering by non-Gaussian entangled states. The Reid steering criterion based on the Heisenberg uncertainty relation fails to detect steerability for many catego…
Experimental detection of steerability in Bell local states with two measurement settings
Adeline Orieux, Marc Kaplan, Vivien Venuti +3
Steering, a quantum property stronger than entanglement but weaker than non-locality in the quantum correlation hierarchy, is a key resource for one-sided device-independent quantu…
Revealing of hidden quantum steerability using local filtering operations
Tanumoy Pramanik, Young-Wook Cho, Sang-Wook Han +3
Nonlocal quantum correlation is at the heart of bizarre nature of quantum physics. While there are various classes of nonlocal quantum correlation, steerability of a quantum state…
Robustness of reference-frame-independent quantum key distribution against the relative motion of the reference frames
Tanumoy Pramanik, Byung Kwon Park, Young-Wook Cho +4
Reference-Frame-Independent quantum key distribution (RFI-QKD) is known to be robust against slowly varying reference frames. However, other QKD protocols such as BB84 can also pro…
Classical light steering leading to quantum-like security
Tanumoy Pramanik, Archan S. Majumdar
We show how single system steering can be exhibited by classical light, a feature originating from superposition in classical optics that also enables entanglement and Bell-violati…
Preservation of quantum key rate in the presence of decoherence
Shounak Datta, Suchetana Goswami, Tanumoy Pramanik +1
It is well known that the interaction of quantum systems with the environment reduces the inherent quantum correlations. Under special circumstances the effect of decoherence can b…
Non-Local Advantage of Quantum Coherence
Debasis Mondal, Tanumoy Pramanik, Arun Kumar Pati
A bipartite state is said to be steerable if and only if it does not have a single system description, i.e., the bipartite state cannot be explained by a local hidden state model.…
