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…

Chebyshev cosmography in the framework of extended symmetric teleparallel theory

Sai Swagat Mishra, N. S. Kavya, P. K. Sahoo +1

Cosmography has been extensively utilized to constrain the kinematic state of the Universe using measured distances. In this work, we propose a new method to reconstruct coupling t…

Unveiling the Effects of Coupling Extended Proca-Nuevo Gravity on Cosmic Expansion with Recent Observations

L. Sudharani, N. S. Kavya, V. Venkatesha

We study Coupling Extended Proca-Nuevo gravity, a non-linear theory extending from dRGT massive gravity with a spin-1 field. This theory is shown to yield reliable, ghost-free cosm…

Can models play a bridge between early and late time Universe?

N. S. Kavya, Sai Swagat Mishra, P. K. Sahoo +1

The ability of Big Bang Nucleosynthesis theory to accurately predict the primordial abundances of helium and deuterium, as well as the baryon content of the Universe, is considered…

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…

Cosmic expansion beyond CDM: Investigating power-law and logarithmic corrections

M. Koussour, N. S. Kavya, V. Venkatesha +1

The cosmic acceleration observed in the expansion of the Universe has sparked extensive research into the nature of dark energy, which is known to constitute approximately 70\% of…
