Spectroscopy is a scientific technique used to analyze the interaction between matter and electromagnetic radiation to determine the composition, structure, and properties of substances. It is fundamental in fields like chemistry, physics, and astronomy for identifying materials and understanding molecular and atomic interactions.

Spectroscopy

Quantum computing leverages the principles of quantum mechanics to process information in ways that classical computers cannot, using qubits that can exist in multiple states simultaneously. This allows for potentially exponential increases in computing power, enabling solutions to complex problems in fields like cryptography, optimization, and materials science.

Quantum Computing

Frequency locking occurs when two oscillating systems adjust their frequencies to match each other, leading to a synchronized state. This phenomenon is crucial in various fields, including electronics, optics, and biology, as it enables the coordination of systems that would otherwise operate independently.

Frequency Locking

Modulation is a technique used in communication systems to modify a carrier signal in order to encode information for transmission. It is essential for efficiently transmitting data over various media, allowing signals to be adapted for different frequencies and bandwidths while minimizing interference and noise.

Modulation

Optical frequency combs are a revolutionary tool in precision measurement, acting as a ruler for light by providing a spectrum of equally spaced, sharp laser lines. They enable the measurement of light frequencies with unprecedented accuracy, facilitating advancements in timekeeping, spectroscopy, and the study of fundamental physics.
