초록

Quantum information technology is driving innovative computing, communication, and sensing advancements. High-performance tunable lasers have become essential tools for precisely controlling and manipulating qubits. These lasers provide high stability and accuracy at specific wavelengths, enabling efficient control of various types of qubit systems, such as ions, neutral atoms, and defects. High-performance tunable lasers allow the initialization of qubit states, execution of quantum gate operations, and minimization of errors during the readout process. In addition, tunable lasers are critical in precisely regulating the interactions between multiple qubits to optimize quantum entanglement and correlation. This study explores the existing and state-of-the-art technologies related to the design and implementation of high-performance tunable lasers in the visible and near-infrared wavelength ranges that are crucial for key material systems used in quantum technology. Based on this investigation, we present new methodologies for maximizing the scalability of qubit control. These laser technologies are expected to contribute to the commercialization and performance enhancement of quantum information technology, a common foundational technology.
