Why Use a Laser for Quantum Technologies?

A laser is more than just a tool. Due to their unmatched accuracy, flexibility, and control, lasers are the fundamental building blocks of Quantum 2.0 scalability and quantum information technology. They are essential for quantum computing, communication, and metrology.

Precision Control for Quantum Computing

Lasers, with their unparalleled ability to control and manipulate quantum states, form the foundation of many quantum computing modalities. They provide the precision and coherence needed for the complex operations of quantum gates, enabling the initialization, modification, and readout of qubit quantum states. This is especially crucial in systems like trapped ion quantum computers, where lasers finely tune the ions' internal and motional states.

High-Speed Quantum Communication

Lasers are essential in quantum communication, enabling the fast information transfer required for advanced quantum key distribution (QKD) techniques. They also ensure high data transmission security by transporting secure quantum information over long distances through fiber optic paths or free space.

Laser Cooling and Trapping: The Key to Stability

Stable quantum state maintenance requires the ability to cool and trap particles, which lasers excel at. By lowering atoms’ temperature to almost absolute zero, methods such as laser cooling help solve two common problems with quantum systems: decoherence and environmental noise.

Scalability and Integration for Quantum Networks

Several groups have successfully showcased working prototypes across the spectrum of quantum sensing and timing, computing, and networking. The market is now ready to take its next steps, including the commercialization of products and the implementation of scalable designs.

As we advance into more complex quantum networks, lasers offer the necessary scalability and integration. Their precise tuning and targeting capabilities are perfect for individually addressing qubits in expansive quantum systems, paving the way for practical and scalable quantum computing and networking solutions.
