[citation needed] Any candidate theory of quantum gravity must be able to reproduce Einstein's theory of general relativity as a classical limit of a quantum theory. This is not guaranteed because of a feature of quantum field theories which is that they have different sectors, these are analogous to the different phases that come about in the ...
General relativity theory expressed in this way, made possible to pursue quantization of it using well-known techniques from quantum gauge field theory. The quantization of gravity in the Ashtekar formulation was based on Wilson loops , a technique developed by Kenneth G. Wilson in 1974 [ 8 ] to study the strong-interaction regime of quantum ...
In quantum information theory, a quantum channel is a communication channel which can transmit quantum information, as well as classical information. An example of quantum information is the general dynamics of a qubit. An example of classical information is a text document transmitted over the Internet.
Quantum cosmology [1] [2] is the attempt in theoretical physics to develop a quantum theory of the universe. This approach attempts to answer open questions of classical physical cosmology , particularly those related to the first phases of the universe.
Open strings attached to a pair of D-branes We move and live in three dimensions: length, width, and height. However, Einstein revealed what was once unimaginable: time is actually a dimension and linked with space itself. To reconcile the massive cosmic and minuscule quantum worlds, physicists are realizing four dimensions may not be enough.
Since LQG is based on a specific quantum theory of Riemannian geometry, [6] [7] geometric observables display a fundamental discreteness that play a key role in quantum dynamics: While predictions of LQC are very close to those of quantum geometrodynamics (QGD) away from the Planck regime, there is a dramatic difference once densities and ...
The problem of quantum cosmology is that the physical states that solve the constraints of canonical quantum gravity represent quantum states of the entire universe and as such exclude an outside observer, however an outside observer is a crucial element in most interpretations of quantum mechanics.
