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…
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…
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 structures of and forms
Sudha, B. N. Karthik, A. R. Usha Devi +1
In their seminal paper (Phys. Rev.121, 920 (1961)) Sudarshan, Mathews and Rau investigated properties of the dynamical and maps acting on dimensional quantum systems. N…
