What is Nonclassical Light?

Nonclassical light refers to a class of light that exhibits properties that cannot be explained by classical electromagnetic theory. These properties include:

• Quantization: Nonclassical light is emitted in discrete units called photons, violating the classical notion of continuous wave propagation.
• Entanglement: Photons from nonclassical light sources can be correlated in ways that cannot be explained by classical probabilities, a phenomenon known as quantum entanglement.
• Squeezing: Nonclassical light can exhibit reduced fluctuations in certain properties, such as phase or amplitude, known as squeezing.

Semiconductor Lasers and LEDs as Nonclassical Light Sources

Semiconductor lasers and LEDs have emerged as promising candidates for generating nonclassical light due to their unique properties. These devices are capable of:

• Precise control: The semiconductor materials used in these devices allow for precise manipulation of the light emission process, enabling the creation of specific nonclassical states.
• Scalability: Semiconductor lasers and LEDs can be manufactured in large quantities, making them cost-effective and suitable for practical applications.
• Compactness: These devices are inherently small and lightweight, allowing for integration into portable and handheld devices.

Applications in Quantum Technologies

The generation of nonclassical light from semiconductor lasers and LEDs holds tremendous potential for advancing quantum technologies, including:

• Quantum communication: Nonclassical light can be used to encode quantum information, enabling secure and ultra-fast communication systems.
• Quantum computing: Nonclassical light can serve as a resource for quantum computation, providing entangled states and squeezed states for quantum logic operations.
• Quantum sensing: Nonclassical light can be used to enhance the sensitivity and resolution of quantum sensing devices, such as atomic clocks and interferometers.

Research and Technological Advancements

The field of nonclassical light generation from semiconductor lasers and LEDs is rapidly evolving, with numerous research groups and companies actively pursuing this area. Key advancements include:

• Development of new semiconductor materials: Engineers are exploring novel semiconductors with tailored bandgaps and defect structures to optimize nonclassical light generation.
