Quantum Mechanics

3. In quantum mechanics, the entity or device that measures a system, causing the wave function to collapse.
6. The path followed by an object moving through space.
7. The basic unit of information in a quantum computer, representing 0, 1, or a superposition of both.
10. The ability of a quantum system to be in multiple states (like dead and alive) at the same time until measured.
13. A system where the future is entirely determined by the past; cause and effect are absolute.
17. The quality of being open to more than one interpretation; inexactness.
18. The physicist known for his Uncertainty Principle, stating you can't know position and momentum simultaneously.
19. A fundamental particle of light that acts as both a wave and a particle.
20. The pattern created when two waves overlap, amplifying or canceling each other out; seen in the double-slit experiment.

1. Something that goes against your gut feeling or common sense, yet is true.
2. A fundamental constituent of matter; protons and neutrons are made of these.
4. A seemingly absurd or self-contradictory statement or proposition that when investigated may prove to be well founded.
5. The quantum phenomenon where a particle passes through a solid barrier that it shouldn't have the energy to cross.
8. The scale of reality that is large enough to be seen with the naked eye; the opposite of the quantum realm.
9. Based on or adapted to a theory of probability; subject to or involving chance variation.
11. The concept that matter exhibits both wave-like and particle-like properties.
12. A phenomenon where two particles become linked and share the same state instantly, regardless of distance.
14. Einstein's theory of space and time, which governs the macroscopic world, often at odds with quantum mechanics.
15. The process by which a quantum system interacts with its environment and loses its quantum behavior, becoming classical.
16. The Austrian physicist famous for a thought experiment involving a cat in a box.
