Significant foreign assignments:
(a) Significant contributions to science and/ or technology development by the nominee
based on the work done in India during most part of last 5 years:
The nominee, ADITI SEN DE, came back to India in December 2008, leaving her Ramon-y-Cajal
position in Spain, and joined the School of Physical Sciences, Jawaharlal Nehru University as an
assistant professor. In August 2009, she joined the Harish-Chandra Research Institute (HRI). Along
with Ujjwal Sen and Arun K Pati, she started a new group, called the quantum information and computation
(QIC) group, which is currently among the leading QIC groups in India and abroad. It has 19
members including Aditi and two more faculties, 6 postdocs, and 10 Ph.D. students. She works on
quantum information and computation (QIC) and at the interface of QIC and many-body
physics, quantum optics and foundations of quantum mechanics.
During the last five years, she has highly productive track records with 63 research papers,
which includes a review article, in top ranking peer reviewed journals like Reports on Prog. in
Phys., Phys. Rev. Lett., Phys. Rev. A, Phys. Rev. B, Phys. Rev. E, New J. Phys., EPL, Phys.
Lett. A, J. Phys. A. She has also cowritten two chapters of two books. She is on the referee
list of all acclaimed journals and is clearly an extremely visible scientist. I nominate her as an
outstanding candidate for Shanti Swarup Bhatnagar Prize For Science and Technology for
excellence in physical sciences.
Aditi has made ground-breaking contributions in recent years towards building quantum information
technology, especially quantum communication networks and their implementations by quantum
optics ( Phys. Rev. A (PRA) (2014) ; PRA (2015); PRA (2016); arXiv:1707.02449; arXiv:
1802.10398). She has significantly contributed towards development of quantum correlations, basic
ingredient in quantum information processing, which is one of the main challenges in quantum

information theory. She has introduced a multiparty entanglement measure based on local measurements
on a multiparty quantum state, and an entanglement measure averaged on the postmeasurement
ensemble (PRA (2017)). She has a series of important works on the problem of
sharability of quantum correlation and information in a multipartite scenario, which forms the
bedrock for quantum cryptography and has important implications for national security (A chapter
of a book, “Lectures on General Quantum Correlations and their Applications”, Springer Publishing
(2017), pp 23–64; PRA (2013); PRA (2013); PRA (2013); PRA (2015)). An almost universal feature in
all quantum information processing tasks is the use of quantum correlations as resource. A main
obstacle in this enterprise is the fragility of entanglement to decoherence, Aditi has made significant
contributions towards such understanding in several of her recent works (PRA (2015);
PRA(2018); arXiv: 1610.00730). On a completely different note, she has shown that the centuryold
Benford's law for different measures of quantum correlations exhibit a universal behavior (EPL
(2016), Selected as Editor’s Choice 2016).
An important discovery made by her is a new analytic recursive method, the density matrix recursion
method, to characterize multisite entanglement of highly superposed states in quantum
many-body systems.
(b) Impact of the contributions in the field concerned:
Quantum Information and computation is one of the most fascinating fields of research around the
world. It is a science at the crossroads of physics, computer science, mathematics, and information
theory, and has the potential of revolutionizing the future of communication and computational technologies.
The nominee is one of scientists who started working in this field from the early stage of
quantum information science as a Ph.D. student with world-leading groups (Prof. Marek Zukwoski
and Prof. Ryszard Horodecki). She has published 121 research articles with a total of 4067 citations
(according to Google Scholar). This makes for an incredibly high 33 citations per paper
on an average. She has published several articles on this subject, 6 of which have citations
more than 100.
The rapid development of quantum information science is largely due to discoveries of communication
protocols using quantum states, specifically by entangled states and their successful realizations.
She has made significant contributions in building quantum communication network, involving
multiple senders and receivers throughout her career. Aditi has worked extensively on distinguishability
of quantum states, which is one of the basic questions in quantum mechanics and plays an important
role in quantum communication theory, including quantum cryptography.
She has worked extensively on the fundamental issues of quantum information which include characterization
and quantification of quantum correlation in bipartite as well as multipartite quantum
states. In particular, she has contributed significantly in recent developments towards understanding
of quantum correlations beyond entanglement in a multiparty system (one of the papers in this direction
has 412 citations and a recent review article in ROPP). Due to her good understanding on quantum
correlations, in last one year, she has obtained invitations to write a chapter of a book, and review
article in Reports on Progress in Physics. All of them are now published, giving her a recognition
in the community of quantum information science and beyond as a leading scientist.
The potential materials realizing a quantum computer are important systems in their own right in the
fields such as quantum statistical mechanics and condensed matter physics. She has extensively
studied statistical mechanical behaviour of quantum correlation in different spin models and is one of
the experts in the study of quantum correlations in the time-dynamics of spin models (see for recent
reviews, see Rev.Mod.Phys.80:517-576,2008; Rev. Mod. Phys. 84, 1655-1707 (2012), ROPP 2018).
See below the bar-plot of her citation from Google scholar. It shows that during last 5 years, the total
number of citations to her work was always more than 350 per year. And in last two years, it is more
than 400.
