We use numerically exact diagonalization to calculate the spin-orbit- and phonon-induced triplet-singlet relaxation rate in a two-electron quantum dot exposed to a tilted magnetic field. Our scheme includes a three-dimensional description of the quantum dot, the Rashba and the linear and cubic Dresselhaus spin-orbit coupling, the ellipticity of the quantum dot, and a full angular description of the magnetic field. We are able to find reasonable agreement with the experimental results of Meunier et al. [Phys. Rev. Lett. 98, 126601 (2007)] in terms of the singlet-triplet energy splitting and the spin relaxation rate, respectively. We analyze in detail the effects of the spin-orbit factors, magnetic-field angles, and dimensionality and discuss the origins of the remaining deviations from the experimental data.

Optimization and performance investigation of 1-Toffoli gate quantum full adders for spin-torque-based n-qubit architecture
Kulkarni, Anant; Haghparast, Majid; Kaushik, Brajesh Kumar (Springer, 2024)Quantum computing (QC) is suitable for reversible computing due to its inherent parallel processing ability and fast speed. It also helps to address the issue of high-power dissipation in classical computing. Moreover, QC ... -
Embracing iterations in Quantum software : a vision
Khan, Arif Ali; Fahmideh, Mahdi; Ahmad, Aakash; Waseem, Muhammad; Niazi, Mahmood; Lahtinen, Valtteri; Mikkonen, Tommi (ACM, 2022)In today’s software engineering, iterations, affordable en masse, form an important part of just about any system. However, not all computing resources are cheap to consume. In High-Performance (HPC) and Quantum Computing ... -
Software architecture for quantum computing systems : a systematic review
Khan, Arif Ali; Ahmad, Aakash; Waseem, Muhammad; Liang, Peng; Fahmideh, Mahdi; Mikkonen, Tommi; Abrahamsson, Pekka (Elsevier BV, 2023)Quantum computing systems rely on the principles of quantum mechanics to perform a multitude of computationally challenging tasks more efficiently than their classical counterparts. The architecture of software-intensive ...
