familiar from quantum mechanics but interpreted in this context as coordinates of a quantum space or spacetime. These relations were proposed by Roger Penrose in his earliest spin network theory of space. It is a toy model of quantum gravity in 3 spacetime dimensions (not the physical 4) with a Euclidean (not the physical Minkowskian) signature.
This was the quantum analog of Shannon's noiseless coding theorem, and it helped to start the field known as quantum information theory. Schumacher is also credited with inventing the term qubit along with William Wootters of Williams College , which is to quantum computation as a bit is to traditional computation.
This is a list of well-known spacetimes in general relativity. [1] Where the metric tensor is given, a particular choice of coordinates is used, but there are often other useful choices of coordinate available.
Sarfatti's ideas relating quantum physics to David Chalmers's "hard problem" (i.e. how our conscious experiences are generated) are mentioned in a paper by Paavo Pylkkänen. [ 11 ] Sarfatti claims to have been recruited by agents of the CIA and DOD to work on both the physics of consciousness and the propulsion of "flying saucers" back in the ...

Nima Arkani-Hamed (Persian: نیما ارکانی حامد; born April 5, 1972) is an Iranian-American-Canadian [3] [4] theoretical physicist, with interests in high-energy physics, quantum field theory, string theory, cosmology and collider physics.
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
His 1995 textbook Foundations of Quantum Group Theory is a standard text still used by researchers today. He also pioneered a quantum groups approach to noncommutative geometry and the use of such methods as a route to quantum gravity, [1] [2] leading in 1994 to the first model with testable predictions of quantum spacetime.
