Application of quantum computing in discrete portfolio optimization

Shunza, Justus; Akinyemi, Mary; Yinka-Banjo, Chika - In: Journal of management science and engineering 8 (2023) 4, pp. 453-464

This study proposes a novel and more efficient quantum algorithm for portfolio optimization using quantum combinatorial optimization (QCO) techniques. A recent construction developed in 2021 has sparked the field of financial portfolio optimization through the Quantum Walk Optimization Algorithm...

Remanent quantum correlations in dissipative qubits

Nizama, Marco; Cáceres, Manuel O. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 23, pp. 6155-6160

Starting from the exact evolution of a Markovian dissipative quantum walk, a non-Markovian decoherence of two qubits … dominates, quantum correlations survive in time as ∝t−1/2. Thus, even under the influence of dissipation, two qubits retain …
