Reduced State Stabilizer Rényi Entropy as a Probe of Quantum Phase Transitions in Frustrated J_1-J_2 Spin Models

George Biswas, Santanu Sarkar, Jun-Yi Wu +1

We investigate whether the second-order purity-corrected stabilizer Rényi entropy (SRE) of reduced two-qubit density matrices can serve as a reliable local indicator of quantum pha…

Reduced-State Stabilizer Rényi Entropy as a Probe of Quantum Criticality in the Transverse ANNNI Model and the Quantum Compass Model

Santanu Sarkar, George Biswas, Jun-Yi Wu +1

We investigate the effectiveness of the stabilizer Rényi entropy (SRE), a quantifier associated with non-stabilizer resources (quantum magic), as an indicator of quantum phase tran…

Enhanced quantum violation of a non-contextual inequality and witnessing quantum dimension

Ritwija Roy, Anindya Biswas

We consider a non-contextual inequality in the sequential measurement scenario and derive the optimal quantum violation of it without assuming the dimension of the system. Since th…

Fidelity and Entanglement of Random Bipartite Pure States: Insights and Applications

George Biswas, Shao-Hua Hu, Jun-Yi Wu +2

We investigate the fidelity of Haar random bipartite pure states from a fixed reference quantum state and their bipartite entanglement. By plotting the fidelity and entanglement on…

Estimating phase transition of perturbed J1-J2 Heisenberg quantum chain in mixtures of ground and first excited states

Sayan Mondal, George Biswas, Ahana Ghoshal +2

We show that the nearest neighbour entanglement in a mixture of ground and first excited states - a subjacent state - of the J1-J2 Heisenberg quantum spin chain can be used as an o…

Black Holes in AdS Einstein Gauss Bonnet Gravity With Power- Yang Mills Field

Anindya Biswas

In this paper we construct an exact spherically symmetric black hole solution with a power Yang-Mills (YM) source in the context of Einstein Gauss-Bonnet gravity ( EGB). W…
