Partial stability of induced entanglement in an off-resonance qutrit-cavity system with nonlinear coupling and intrinsic decoherence

AEJ - Alexandria Engineering Journal, 2022
In this article, we introduce an analytical description for the nonlinear off-resonance qutrit-cavity system through intensity-dependent nonlinear coupling under intrinsic decoherence.

High-fidelity qutrit entangling gates for superconducting circuits [PDF]

Nature Communications, 2022
Ternary quantum information processing in superconducting devices poses a promising alternative to its more popular binary counterpart through larger, more connected computational spaces and proposed advantages in quantum simulation and error correction.

Security analysis of qutrit quantum secret sharing with linear optical correlation measurement [PDF]

Scientific Reports
In this paper, we investigate a possibility of three-dimensional extension of correlation measurement based quantum secret sharing (QSS) with a three-dimensional cyclic-entangled state, called qutrit cyclic-entangled state.

Cyclic assisted cloning of arbitrary unknown single-particle states in amplitude damping channel. [PDF]

PLoS ONE
In this paper, two conclusive three-party cyclic assisted cloning protocols in amplitude damping (AD) channel are put forward that, respectively clone three arbitrary unknown single-qubit states and single-qutrit states with the help of a state preparer.

Symmetry-Induced Emergence of a Pseudo-Qutrit in the Dipolar Coupling of Two Qubits [PDF]

Entropy, 2022
We investigate a system of two identical and distinguishable spins 1/2, with a direct magnetic dipole–dipole interaction, in an external magnetic field. Constraining the hyperfine tensor to exhibit axial symmetry generates the notable symmetry properties

Quantum Tomography of Two-Qutrit Werner States

Photonics, 2022
In this article, we introduce a framework for two-qutrit Werner states tomography with Gaussian noise. The measurement scheme is based on the symmetric, informationally complete positive operator-valued measure. To make the framework realistic, we impose

Generation of Entanglement in Qutrit Spin Coherent States by Nonlinear Hamiltonian [PDF]

Journal of Sciences, Islamic Republic of Iran, 2021
We study entanglement in coherent spin states and several superpositions of multi-qutrit coherent states evolved under the one-axis counter-twisting Hamiltonian in the presence and absence of a magnetic field.
