Definition

C1General Physics

(technical, academic)The smallest possible value a physical quantity can reach according to quantum mechanics.

Example

  • At the quantum limit, classical physics no longer provides accurate descriptions.

C1Measurement

(technical, academic)The fundamental limit on measurement accuracy due to the effects of quantum mechanics.

Example

  • The quantum limit restricts how precisely we can measure certain properties of particles.

C2Optics and Photonics

(technical, academic)The maximum sensitivity or resolution achievable, constrained by the quantization of light.

Example

  • Advanced detectors are designed to approach the quantum limit in sensitivity.

C2Electronics and Signal Processing

(technical, academic)The fundamental limit on the signal-to-noise ratio due to the discrete nature of charge carriers.

Example

  • Engineers work to minimize the impact of the quantum limit on electronic noise.
