Simulating the effect of weak measurements by a phase damping channel and determining different measures of bipartite correlations in nuclear magnetic resonance
Akanksha Gautam, Varad R. Pande, Amandeep Singh +2
Quantum discord is a measure based on local projective measurements which captures quantum correlations that may not be fully captured by entanglement. A change in the measurement…
Experimental Detection of Non-local Correlations using a Local Measurement-Based Hierarchy on an NMR Quantum Processor
Amandeep Singh, Dileep Singh, Vaishali Gulati +2
The non-local nature of the correlations possessed by quantum systems may be revealed by experimental demonstrations of the violation of Bell-type inequalities. Recent work has pla…
Generation and Detection of Quantum Correlations and Entanglement on a Spin-Based Quantum Information Processor
Amandeep Singh
This thesis focuses on the experimental creation and detection of a variety of quantum correlations using nuclear magnetic resonance hardware. Quantum entanglement, being most comm…
Experimental Detection of Qubit-Ququart Pseudo-Bound Entanglement using Three Nuclear Spins
Amandeep Singh, Akanksha Gautam, Arvind +1
In this work, we experimentally created and characterized a class of qubit-ququart PPT (positive under partial transpose) entangled states using three nuclear spins on an nuclear m…
Experimentally identifying the entanglement class of pure tripartite states
Amandeep Singh, Kavita Dorai, Arvind
We use concurrence as an entanglement measure and experimentally demonstrate the entanglement classification of arbitrary three-qubit pure states on a nuclear magnetic resonance (N…
Experimental Classification of Entanglement in Arbitrary Three-Qubit States on an NMR Quantum Information Processor
Amandeep Singh, Harpreet Singh, Kavita Dorai +1
We undertake experimental detection of the entanglement present in arbitrary three-qubit pure quantum states on an NMR quantum information processor. Measurements of only four obse…
Experimental demonstration of selective quantum process tomography on an NMR quantum information processor
Akshay Gaikwad, Diksha Rehal, Amandeep Singh +2
We present the first NMR implementation of a scheme for selective and efficient quantum process tomography without ancilla. We generalize this scheme such that it can be implemente…
Witnessing nonclassical correlations via a single-shot experiment on an ensemble of spins using NMR
Amandeep Singh, Arvind, Kavita Dorai
A bipartite quantum system in a mixed state can exhibit nonclassical correlations, which can go beyond quantum entanglement. While quantum discord is the standard measure of quanti…
Entanglement detection on an NMR quantum information processor using random local measurements
Amandeep Singh, Arvind, Kavita Dorai
Random local measurements have recently been proposed to construct entanglement witnesses and thereby detect the presence of bipartite entanglement. We experimentally demonstrate t…
