Why Use a Laser for Quantum Technologies?

Lasers are crucial for Quantum 2.0 scalability and quantum information technology. Their unmatched control, precision, and versatility make them essential for communication, metrology, and quantum computing.

Precision Control for Quantum Computing

Lasers are the foundation of numerous forms of quantum computing, providing unparalleled control and manipulation of quantum states. Lasers provide the precision and coherence required for the sophisticated 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 emotional states.

High-Speed Quantum Communication

Lasers are crucial in quantum communication. They enable high-speed information transfer required for cutting-edge quantum key distribution techniques. Secure quantum information can be transmitted over long distances using lasers, whether through free space or along fiber optic paths, ensuring high levels of data security.

Laser Cooling and Trapping: The Key to Stability

Lasers are particularly effective at cooling and trapping particles, essential for maintaining stable quantum states. Laser cooling, for example, brings atoms to temperatures close to absolute zero, significantly reducing environmental noise and decoherence, which are common challenges in quantum systems.

Scalability and Integration for Quantum Networks

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

As society progresses toward more complex quantum networks, lasers provide the scalability and integration required. Their precise tuning and targeting capabilities make them perfect for individually addressing qubits in large quantum systems, enabling practical and scalable quantum computing and networking solutions.
