In Niven's novel Ringworld's Children the Ringworld itself is converted into a gigantic Quantum II hyperdrive and launched into hyperspace while within its star's gravity well.

* Quantum gravity

Quantum gravity can be treated as an effective field theory.

Quantum field theory on curved ( non-Minkowskian ) backgrounds, while not a full quantum theory of gravity, has shown many promising early results.

* Quantum gravity, a general term for theories intended to quantize general relativity

The article " Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity ", published in the Social Text Spring / Summer 1996 " Science Wars " issue, proposed that quantum gravity is a social and linguistic construct.

Sokal wrote " Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity ", an article proposing that quantum gravity has progressive political implications, and that the " morphogenetic field " ( characterized by Sokal as " a bizarre New Age concept due to Rupert Sheldrake ") could be a cutting-edge theory of quantum gravity.

Quantum effects such as the Casimir effect cannot violate the averaged null energy condition in any neighborhood of space with zero curvature, but calculations in semiclassical gravity suggest that quantum effects may be able to violate this condition in curved spacetime.

Pullin's book ( with R. Gambini ) Loops, Knots, Gauge Theories and Quantum Gravity surveys the state of the art in loop quantum gravity at the time of its publication.

Quantum gravity is believed to be background-independent ( in some suitable sense ), and TQFTs provide examples of background independent quantum field theories.

* String theory and Quantum gravity

Quantum nonlocality is often proposed as a mechanism for superluminal communication.

Quantum oscillations is another experimental technique where high magnetic fields are used to study material properties such as the geometry of the fermi surface.

Quantum brute force is easily defeated by doubling the key length, which has little extra computational cost in ordinary use.

According to a poll at a Quantum Mechanics workshop in 1997 ,< ref > the Copenhagen interpretation is the most widely-accepted specific interpretation of quantum mechanics, followed by the many-worlds interpretation.

Quantum mechanics under the Copenhagen Interpretation interpreted probability as a physical phenomenon, which is what Jaynes called a Mind Projection Fallacy.

A similar view is adopted in Quantum Information Theories.

This has been demonstrated in the famous Lamb-Retherford experiment and was the starting point for the development of the theory of Quantum electrodynamics ( which is able to deal with these vacuum fluctuations and employs the famous Feynman diagrams for approximations using perturbation theory ).

Bernard d ' Espagnat a French theoretical physicist best known for his work on the nature of reality wrote a paper titled The Quantum Theory and Reality according to the paper: " The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment.

" In an article in the Guardian titled Quantum weirdness: What we call ' reality ' is just a state of mind d ' Espagnat wrote that:

A more advanced Quantum II Hyperdrive introduced later is able to cover the same distance in one and a quarter minutes ( 420, 768 x c ).

Quantum mechanics is of a wider scope, as it encompasses classical mechanics as a sub-discipline which applies under certain restricted circumstances.

Quantum mechanics has superseded classical mechanics at the foundational level and is indispensable for the explanation and prediction of processes at molecular and ( sub ) atomic level.

Quantum mechanics is a set of principles describing physical reality at the atomic level of matter ( molecules and atoms ) and the subatomic ( electrons, protons, and even smaller particles ).

Although Schrödinger himself after a year proved the equivalence of his wave-mechanics and Heisenberg's matrix mechanics, the reconciliation of the two approaches and their modern abstraction as motions in Hilbert space is generally attributed to Paul Dirac, who wrote a lucid account in his 1930 classic Principles of Quantum Mechanics.

The first complete mathematical formulation of this approach is generally credited to John von Neumann's 1932 book Mathematical Foundations of Quantum Mechanics, although Hermann Weyl had already referred to Hilbert spaces ( which he called unitary spaces ) in his 1927 classic paper and book.

Quantum field theory has driven the development of more sophisticated formulations of quantum mechanics, of which the one presented here is a simple special case.

Physicist Lee Smolin writes in Three Roads to Quantum Gravity that topos theory is " the right form of logic for cosmology " ( page 30 ) and " In its first forms it was called ' intuitionistic logic '" ( page 31 ).

* Quantum mechanics: In quantum mechanics, which deals with the behavior of very small objects, it is not possible to observe a system without changing the system, and the " observer " must be considered part of the system being observed.

Quantum mechanics ( QM – also known as quantum physics, or quantum theory ) is a branch of physics dealing with physical phenomena at microscopic scales, where the action is on the order of the Planck constant.

Planck is considered the father of the Quantum Theory

Quantum mechanics is essential to understanding the behavior of systems at atomic length scales and smaller.

Quantum coherence is an essential difference between classical and quantum theories, and is illustrated by the Einstein-Podolsky-Rosen paradox.
