Discussion Overview

The discussion revolves around real-life examples and consequences of quantum theory, particularly focusing on technologies that have emerged from quantum mechanics. Participants explore various applications across different fields, including electronics, optics, and materials science.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • Some participants mention the transistor as a fundamental technology derived from quantum theory, essential for modern electronics.
  • Others highlight the laser and superconducting quantum interference devices (SQUIDs) as significant applications of quantum mechanics.
  • One participant notes that modern chemistry heavily incorporates quantum mechanics, suggesting that high school chemistry students are exposed to more quantum concepts than those in physics.
  • Another participant points out that solid-state electronics, including diode lasers used in CD players and superconductors utilized in MRI equipment, are rooted in quantum principles.
  • The Scanning Tunnelling Microscope is proposed as an excellent application of quantum tunnelling effects.
  • Photonic crystals are mentioned as a technology that can facilitate the creation of surface-emitting quantum-cascade lasers.

Areas of Agreement / Disagreement

Participants generally agree on the existence of various technologies that stem from quantum theory, but there is no consensus on a comprehensive list or ranking of these technologies.

Contextual Notes

Some claims depend on specific definitions of technologies and may not encompass all potential applications of quantum theory. The discussion does not resolve the extent to which each example is influenced by quantum mechanics.

Who May Find This Useful

Readers interested in the practical implications of quantum theory, including students and professionals in physics, engineering, and technology development.

What are some real life examples or consequences of quantum theory?
I.E-new technologies... and such.
Thanks

The transistor, which almost all modern electronics are based upon, is one of the most important examples.
 
The laser and the SQUID, for two more. All of modern chemistry (students who take high school chemistry get more quantum mechanics than those who take high school physics).
 
(that's solid-state electronics; the valves etc are pure classical physics)

Other examples: diode laser (e.g. in your CD player), superconductors (so MRI equipment, for example), CCDs (e.g. your digital camera), SQUIDs, ...
 
I suppose the Scanning Tunnelling Microscope is an excellent application how one uses the quantum tunnelling effect.
 
How about Photonic Crystals. They can be used to make surface-emitting quantum-cascade lasers.
