Dicke superposition probes for noise-resilient Heisenberg and super-Heisenberg Metrology
Sudha, B. N. Karthik, K. S. Akhilesh +1
Phase sensing with entangled multi-qubit states in the presence of noise is a central theme of modern quantum metrology. The present work investigates Dicke state superposition pro…
Three-qubit W state tomography via full and marginal state reconstructions on ibm_osaka
H. Talath, B. P. Govindaraja, B. G. Divyamani +3
We present a three-qubit quantum state tomography scheme requiring a set of 17 measurement settings, significantly reducing the experimental overhead compared to the conventional 6…
Lorentz canoncial forms of two-qubit states
Sudha, A. R. Usha Devi, B. N. Karthik +4
The Bloch sphere provides an elegant way of visualizing a qubit. Analogous representation of the simplest composite state of two-qubits has attracted significant attention. Here we…
Entanglement and volume monogamy features of permutation symmetric N-qubit pure states with N-distinct spinors: GHZ and WWbar states
Sudha, Usha Devi A R, Akshata Shenoy H +4
We explore the entanglement features of pure symmetric N-qubit states characterized by N-distinct spinors with a particular focus on the Greenberger-Horne-Zeilinger(GHZ) states and…
Lorentz invariants of pure three-qubit states
A R Usha Devi, Sudha, H Akshata Shenoy +2
Extending the mathematical framework of Phys. Rev. A 102, 052419 (2020) we construct Lorentz invariant quantities of pure three-qubit states. This method serves as a bridge between…
Canonical steering ellipsoids of pure symmetric multiqubit states with two distinct spinors and volume monogamy of steering
B G Divyamani, I Reena, Prasanta K Panigrahi +2
Quantum steering ellipsoid formalism provides a faithful representation of all two-qubit states and helps in obtaining correlation properties of the state through the steering elli…
