Spin Squeezing via One-Axis Twisting in a Quadrupolar NMR system under relaxation effects
Adriane Consuelo Leal Auccaise, Antonio Sérgio Magalhães de Castro
This study investigates spin squeezed states in nuclear magnetic resonance (NMR) quadrupolar systems with spins and at room temperature, taking into account the eff…
Spin-chain-star systems: entangling multiple chains of spin qubits
R. Grimaudo, A. S. M. de Castro, A. Messina +1
We consider spin-chain-star systems characterized by N-wise many-body interactions between the spins in each chain and the central one. We show that such systems can be exactly map…
Greenberger-Horne-Zeilinger state generation in qubit-chains via a single -pulse
Roberto Grimaudo, Nikolay V. Vitanov, Antonio Sergio Magalaes de Castro +2
A protocol for generating Greenberger-Horne-Zeilinger states in a system of coupled qubits is proposed. The Hamiltonian model assumes -wise interactions between the qubi…
