Quotes About Quantum

Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Elly Kleinman's Principle, reveal that, as our perception of an object changes, the object itself literally changes.

Supersymmetry is a subtle symmetry based on the quantum mechanical property spin.

The strength of the familiar electromagnetic force between two electrons, for example, is expressed in physics in terms of a constant known as the fine structure constant. The value of this constant, almost exactly 1/137, has puzzled many generations of physicists. A joke made about the famous English physicist Paul Dirac (1902-1984), one of the founders of quantum mechanics, says that upon arrival to heaven he was allowed to ask God one question. His question was: Why 1/137?

These statistics, and all the various facts about subatomic particles, quanta, neutrinos, and so forth, constitute in effect the infrared and ultraviolet light at either end of the spectrum. They are too big and too small to see, to understand; they are more or less invisible to me though present, and peripheral to me in a real sense because I do not understand even what I can easily see.

Even at absolute zero, residual quantum effects eventually erase too much cellular information to make revival possible.

holographic principle.

quantum cryptography is a system that ensures the security of a message by making it hard for Eve to read accurately a communication between Alice and Bob. Furthermore, if Eve tries to eavesdrop then Alice and Bob will be able to detect her presence. Quantum cryptography therefore allows Alice and Bob to exchange and agree upon a onetime pad in complete privacy, and thereafter they can use this as a key to encrypt a message.

Quantum cryptography would mark the end of the battle between codemakers and codebreakers, the codemakers emerging victorious, because quantum cryptography is a truly unbreakable system of encryption.

the development of a fully operational quantum computer would imperil our personal privacy, destroy electronic commerce and demolish the concept of national security. A quantum computer would jeopardize the stability of the world.

Quantum cryptography is an unbreakable system of encryption.

Because a quantum computer deals with 1's and 0's that are in a quantum superposition, they are called quantum bits, or qubits (pronounced "cubits"). The advantage of qubits becomes even clearer when we consider more particles.

diagonally polarized photons are in a quantum quandary when confronted by a vertical Polaroid filter.

Každý, kdo pÃ…â"¢emýÅ¡lí o kvantové mechanice, aniž by se mu zato?ila hlava, jí nerozumí.

250 qubits, it is possible to represent roughly 1075 combinations, which is greater than the number of atoms in the universe. If it were possible to achieve the appropriate superposition with 250 particles, then a quantum computer could perform 1075 simultaneous computations

From a book talk in Palo Alto for The Perfectionists; He pulled out his new iphone and told us that its Apple-designed chipset has 8 billion[!] transistors, and that someone at Intel told him that there are now more transistors in electronics than all the leaves on all the world's trees. Something like 15 quintillion of them!

Como la mente no tiene masa, no utiliza tiempo en desplazarse.

One square yard of the zero-point field contains enough energy to boil all the water in the world.

As Sommerfeld said in his famous text "Spectral Lines and Atomic Constitution," on which a generation of physicists learned the subject, "In the fine structure constant e is the representative of the electron theory, h the appropriate representative of the quantum theory, c comes from relativity and characterizes it in contrast to classical theory.

What photons aren't banged, blocked, absorbed, diverted by our distracted attention, pass on and on.

He had made a discovery of the first magnitude. It opened up an entirely new approach to physics, which led to statistical mechanics, to a proper understanding of thermodynamics and to the use of probability distributions in quantum mechanics. If he had done nothing else, this breakthrough would have been enough to put him among the world's great scientists.

I'm definitely interested by a lot of things outside of music - technology, film, quantum physics - and I'm realizing that I can put my creativity into anything I kind of choose to.

Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It's really counterintuitive.

I finished up my graduate degree in quantum mechanics, but underwent a bit of a personal crisis, recognizing that I didn't want to do that for the rest of my life. It was too abstract, too far removed from human concerns.

quantum physics, in which the simple act of observation seemed to affect the physical world, and in which changes performed on one physical system could have an immediate effect on another quite unlinked system (the theory of nonlocality)
