Why Use a Laser for Quantum Technologies?

Lasers are not simply tools. They are the foundation of quantum information technology and Quantum 2.0 scalability. Their exceptional accuracy, flexibility, and control make them useful in quantum computing, communication, and metrology.

Precision Control for Quantum Computing

Lasers are the foundation of numerous types of quantum computing, providing unparalleled control and manipulation of quantum states. Lasers offer the accuracy and coherence required for the complex operations of quantum gates, whether they are used to initialize, manipulate, or read the quantum states of qubits. This is especially important in systems such as trapped ion quantum computers, where lasers fine-tune the ions' internal and motional states.

High-Speed Quantum Communication

Lasers play a crucial role in quantum communication. They enable high-speed information transfer required for cutting-edge quantum key distribution (QKD) techniques. Secure quantum information can be sent over vast distances using lasers, whether in free space or along fiber optic paths, ensuring high levels of data security.

Laser Cooling and Trapping: The Key to Stability

Lasers are very effective in cooling and trapping particles, which is essential for maintaining stable quantum states. Laser cooling, for example, brings atoms to temperatures close to absolute zero, considerably lowering external noise and decoherence, which are major challenges in quantum systems.

Scalability and Integration for Quantum Networks

Several organizations have exhibited functioning prototypes in quantum sensing, timing, computing, and networking. The industry is now ready for the next step: implementing scalable designs and commercializing products.

Lasers offer the scalability and integration required as the world moves into increasingly intricate quantum networks. Their ability to precisely tune and target qubits in large-scale quantum systems opens up new possibilities for scalable and useful quantum computing and networking applications.

Adaptability for Diverse Quantum Technologies

Lasers stand out because of their versatility. With various wavelengths, energies, and pulse durations, they are ideal for meeting the unique needs of various quantum technologies. This adaptability is critical for designing lasers to meet the unique requirements of various quantum systems, ranging from atoms and ions to solid-state qubits.
