Can Quantum Physics be weaponized?

Click For Summary

Discussion Overview

The discussion explores the potential for quantum physics to be applied in weaponry, drawing parallels to the historical development of nuclear weapons from special relativity. Participants examine various theoretical applications, existing technologies, and speculative ideas regarding quantum mechanics and its implications for future weaponization.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that quantum physics played a more significant role in the development of nuclear weapons than special relativity, citing the study of nuclear properties and processes.
  • Others propose that modern chemistry, grounded in quantum mechanics, could lead to the discovery of new explosive materials.
  • A participant mentions existing weapons technologies that utilize quantum physics, such as lasers and EMP devices, and discusses the potential for future applications like fusion-powered weapons.
  • There are speculative ideas about weaponizing Bose-Einstein condensates, with one participant describing a theoretical process of converting bosons to fermions that could lead to explosive outcomes.
  • Some participants humorously suggest unconventional ideas about weaponization, including the weight of quantum mechanics textbooks and fictional concepts like sharks with laser beams.
  • The discussion includes references to quantum computers and their potential use in cryptanalysis as a form of weaponization.
  • Several participants express skepticism about the feasibility of certain ideas, questioning the practicality of weaponizing specific quantum phenomena.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility or implications of weaponizing quantum physics. Multiple competing views and speculative ideas remain, with some participants expressing skepticism about certain claims while others explore them further.

Contextual Notes

Some discussions involve speculative ideas that depend on unproven assumptions or theoretical constructs, such as the conversion of bosons to fermions. The practicality of many proposed applications remains unresolved.

Only zombie is an eigenvector of such operator.

I thought of a better quantum weapon: take a very large count of fermions (quarks, electrons, whatever), speed it up to a high velocity relative to your enemy and set its trajectory so it goes through your enemy's heart.

Remind me to never piss of a quantum physicist... :biggrin:

I heard somewhere that there is an "agreement", probably informal, that certain forms of directed energy weapons are not to be used against enemy personnel directly, rather only enemy infrastructure.

For example, using high energy lasers to permanently blind the opponent personnel(versus temporary blinding/hearing loss, such as in flash-bang grenades) is considered cruel.

Blinding lasers are barred by the Geneva Conventions, but there is wiggle-room with "dazzling" lasers, or microwave "pain rays". Not really surprising, the conventions bar even the use of expanding/fragmenting ammunition as well. There is nothing to stop the use of a lethal DEW however, but the issue is energy generation, storage, and blooming in atmosphere or target ablation.

I don't think we should be after war. What do you guys think?

War is too complex in any given situation to simply "yea or nay" it. Generally, I think it should be avoided if other means can achieve a favorable result. Sometimes, waiting to engage is a crime too.
