To what extent is standard quantum mechanics actually non ...

With not just one, but two complete formulations of quantum mechanics in hand, the quantum theory grew explosively. It was applied to atoms, molecules, and ...

How Big Can the Quantum World Be? Physicists Probe the Limits.

A quantum particle in a superposition, contrary to common belief, is not really in two (or more) states at once. Rather, a superposition means ...

Quantum Theory - an overview | ScienceDirect Topics

Quantum theory does not predict with certainty the outcome of every experiment. However, quantum theory predicts average values or, more generally, the ...

Quantum non-locality and beyond - Lecture 2 - YouTube

of quantum mechanics, non-locality is now understood to be one of the main aspects of nature. Popescu will explain, in elementary terms, what ...

Quantum Theory - an overview | ScienceDirect Topics

... quantum theory to quantum mechanics. Recall that what we have been calling quantum theory is really a collection of theories applied to different phenomena ...

Does Quantum Physics Prove there is no such thing as Matter?

My understanding so far, is that, at the root of quantum physics, we have discovered that matter (atoms/subatomic particles) does not exist at a ...

Beyond quantum theory - IQOQI Vienna

Due to the high cost of describing many-body quantum states, extracting predictions from quantum physics is typically impossible. If we used all the computers ...

Quantum theory and human perception of the macro-world - PMC

It remains a possibility that standard quantum theory is an incomplete theory, and hence incapable of coping ultimately with separated entities, meaning that a ...

New theory seeks to unite Einstein's gravity with quantum mechanics

Quantum mechanics. All the matter in the universe obeys the laws of quantum theory, but we only really observe quantum behaviour at the scale of ...

Our world (still) cannot be anything but quantum, say physicists

Their verdict is clear: no classical macroscopic theory can truly describe reality. The work also provides further proof that a particle can ...

Quantum Physics Falls Apart without Imaginary Numbers

But physicists are not convinced that standard quantum theory is true. One reason is that it seems to conflict with one of our other theories, ...

Relativity versus quantum mechanics: the battle for the universe

Taking a larger view, the real issue is not general relativity versus quantum field theory, Carroll explains, but classical dynamics versus ...

Quantum nonlocality does not exist - PNAS

Nonlocality is a standard example of a quantum mechanical property not present in classical mechanics. ... actually unitary, but this is not ...

Quantum mechanics | Institute of Physics

To an even greater extent than relativity, quantum mechanics today pervades all areas of fundamental physics – from matter's building blocks to the big bang and ...

Einstein on the Completeness of Quantum Theory

If the quantum wave is not a complete description of the physical system, then Einstein has a ready explanation of the probabilities that have now entered into ...

In Two Place At Once. Unraveling the mystery of quantum…

Without quantum physics, we would not know what we are made of, let alone what stars and galaxies are made of, nor would we understand the ...

Quantum Theory and the Structure of Space-Time - De Gruyter

But, of course, we know that probabilities do not interfere, probability amplitudes do. And if it is a probability wave, what physical meaning ...

Why the foundations of physics have not progressed for 40 years

But all shortcomings of these theories – the lacking quantization of gravity, dark matter, the quantum measurement problem, and more – have been ...

Does quantum mechanics ever really quantize classical mechanics?

But I was speaking to what I believed was the point of your previous remark, in that the presence of superpositions in one's mechanics is not ...

A Theory of Everything That Explains Away The Paradoxes of ...

Of course, this is a controversial idea. Physicists have long considered the possibility that quantum mechanics is incomplete, that it is ...
