Geometric phase and entanglement for massive spin-1 particles

Controlled Dense Coding with Symmetric State

“…It is noted that normalized condition α 2 + δ 2 + γ 2 + δ 2 = 1 should be satisfied in (1). Under the case of α = δ = γ = δ = 1/4, | 123 is a generalized GHZ state [32]. In order to control the amount of information transmitted from Alice to Bob in the quantum channel with entanglement, after performing a von Neumann measurement on his qubit under the basis,…”

“…Moreover, it is also common in atomic and molecular physics to consider the cases of the three particles and their resonances. Therefore, it is interesting to investigate three-qubit symmetric state for the dense coding [32].…”

Nonadiabatic Geometric Quantum Computation by Straightway Varying Parameters of Magnetic: A New Design

“…Recently, geometric phase has been attracting increasing interest because of its importance for understanding and implementing quantum computation in real physical systems [5][6][7][8][9]. Geometric quantum computation is a scheme intrinsically fault-tolerant and therefore resilient to certain types of computational errors.…”

Geometric Population Inversion in Rabi Oscillation

“…It is known that a quantum state may retain a memory of its motion in terms of a geometric phase [1][2][3][4][5][6], when it undergoes a closed evolution in parameter space. In fact, the geometric phase essentially arises as an effect of parallel transport in the Poincaré representation of the manifold [7][8][9][10][11].…”
