More nonlocality with less incompatibility in higher dimensions: Bell vs prepare-measure scenarios
Sudipta Mondal, Pritam Halder, Saptarshi Roy +1
Connecting incompatibility in measurements with the violation of local realism is one of the fundamental avenues of research. For two qubits, any incompatible pair of projective me…
Measurement-based qudit quantum refrigerator with subspace cooling
Debkanta Ghosh, Tanoy Kanti Konar, Aditi Sen De
We develop a method to transform a collection of higher-dimensional spin systems from the thermal state with a very high temperature of a local spin-s Hamiltonian to a low-lying en…
Creating two-qudit maximally entangled quantum link through bulk
Keshav Das Agarwal, Sudip Kumar Haldar, Aditi Sen De
We design a set-up for creating maximally entangled two-qudit links between distant nodes which are weakly coupled with interacting spin-s bulk (processor). We exhibit that such qu…
Deciding factor for detecting a particle within a subspace via dark and bright states
Aashay Pandharpatte, Pritam Halder, Aditi Sen De
In a measurement-induced continuous-time quantum walk, we address the problem of detecting a particle in a subspace, instead of a fixed position. In this configuration, we develop…
Discovering Factorization Surface of Quantum Spin Chains with Machine Learning
Nakul Aggarwal, Keshav Das Agarwal, Tanoy Kanti Konar +2
Entanglement in quantum many-body systems is required for a variety of quantum information tasks, making it crucial to identify the parameter space in which the ground state is ful…
