quantum limit
The term 'quantum limit' describes the ultimate boundaries imposed by quantum mechanics on various physical measurements and processes.
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.
