Robust entanglement detection in arbitrary two-mode Gaussian state: a Stokes-like operator-based approach
Arijit Dutta, Sibasish Ghosh, Jaewan Kim +1
Detection of entanglement in quantum states is one of the most important problems in quantum information processing. However, it is one of the most challenging tasks to find a univ…
Effects of white noise on Bell theorem for qudits
Arijit Dutta, Jaewan Kim, Jinhyoung Lee
We introduce two types of statistical quasi-separation between local observables to construct two-party Bell-type inequalities for an arbitrary dimensional systems and arbitrary nu…
Thermal transitions of the modulated superfluid for spin-orbit coupled correlated bosons in an optical lattice
Arijit Dutta, Abhishek Joshi, K. Sengupta +1
We investigate the thermal physics of a Bose-Hubbard model with Rashba spin-orbit coupling starting from a strong coupling mean-field ground state. The essential role of the spin-o…
Optimal Usage of Quantum Random Access Memory in Quantum Machine Learning
Jeongho Bang, Arijit Dutta, Seung-Woo Lee +1
By considering an unreliable oracle in a query-based model of quantum learning, we present a tradeoff relation between the oracle's reliability and the reusability of quantum state…
Geometric extension of Clauser-Horne inequality to more qubits
Arijit Dutta, Tschang-Uh Nahm, Jinhyoung Lee +1
We propose a geometric multiparty extension of Clauser-Horne (CH) inequality. The standard CH inequality can be shown to be an implication of the fact that statistical separation b…
Spatial behavior in a Mott insulator near the voltage-driven resistive transition
Arijit Dutta, Pinaki Majumdar
We develop a real space theory of the voltage bias driven transition from a Mott insulator to a correlated metal. Within our Keldysh mean field approach the problem reduces to a se…
Clearer visibility Hong-Ou-Mandel effect with correlation function based on rates rather than intensities
Krzysztof Rosołek, Kamil Kostrzewa, Arijit Dutta +3
We test ideas put forward e.g in arXiv:1508.02368, which suggest that using rates in quantum optics can lead to better indicators of non-classicality for states of quantum optical…
Simple criteria for noise resistance of two qudit entanglement
Arijit Dutta, Junghee Ryu, Wieslaw Laskowski +1
Too much noise kills entanglement. This is the main problem in its production and transmission. We use a handy approach to indicate noise resistance of entanglement of a bi-partite…
Geometrical Bell inequalities for arbitrarily many qudits with different outcome strategies
Marcin Wieśniak, Arijit Dutta, Junghee Ryu
Greenberger-Horne-Zeilinger states are intuitively known to be the most non-classical ones. They lead to the most radically nonclassical behavior of three or more entangled quantum…
Geometric Bell-like inequalities for steering
Marek Żukowski, Arijit Dutta, Zhi Yin
Many of the standard Bell inequalities (e.g., CHSH) are not effective for detection of quantum correlations which allow for steering, because for a wide range of such correlations…
Detection efficiency loophole in Pusey-Barrett-Rudolph theorem
Arijit Dutta, Marcin Pawlowski, Marek Zukowski
Detection efficiency loophole poses a significant problem for experimental tests of Bell inequalities. Recently discovered Pusey-Barrett-Rudolph (PBR) theorem suffers from the same…
Geometric chained inequalities for higher-dimensional systems
Marek Żukowski, Arijit Dutta
For systems of an arbitrary dimension, a theory of geometric chained Bell inequalities is presented. The approach is based on chained inequalities derived by Pykacz and Santos. For…
Translating Concepts of State Transfer to Spin-1 Chains
Marcin Wiesniak, Arijit Dutta, Jeonghee Ryu
State transfer is a well-known routine for various systems of spins-. Still, it is not well studied for chains of spins of larger magnitudes. In this contribution we arg…
Multisetting Bell inequalities for spins-1 avoiding KS contradiction
Arijit Dutta, Marcin Wieśniak, Marek Żukowski
Bell's theorem for systems more complicated than two qubits faces a hidden, as yet undiscussed, problem. One of the methods to derive Bell's inequalities is to assume existence of…
