Neutral atom quantum computers are gaining significant attention for their exceptional scalability. This scalability is achieved through two primary techniques: the optical lattice method, which arranges atoms in a regular grid using laser fields, and the optical tweezer-based approach. The optical tweezer system is particularly advantageous because it allows for easy scaling of the qubit count. By simply increasing the laser intensity, the number of optical tweezers—and therefore qubits—can be expanded without difficulty.
Another notable benefit of the neutral atom platform is the strong connectivity between qubits. Using holographic methods, optical tweezers can be arranged in three-dimensional space, enabling entanglement and interaction between all qubits. This is particularly advantageous for solving complex combinatorial optimization problems and similar computational challenges.
SDT combines expertise in laser manipulation and optical trapping with advanced FPGA-based digital and analog technology, contributing to the development of neutral atom quantum computing. Leveraging these capabilities, SDT aims to develop a 3D neutral atom quantum computer with 300 qubits by the end of 2026.
