Quantum mechanics describes the microscopic properties of nature in a regime where classical mechanics no longer applies. It explains phenomena such as the wave-particle duality, quantization of energy, and the uncertainty principle and is generally used in single-body systems. Use the quantum-field-theory tag for the theory of many-body quantum-mechanical systems.

I don't understand the no-communication theorem
To communicate a particular bit sequence from Alice to Bob, there must be a fixed assignment of a logical 1 to a state, say, s1, and a logical 0 to s2. But when Alice measures her object, the outcome …

About the complex nature of the wave function?
Already great answers to this often asked question. Very simply put tho, quantum eigenstates have associated relative phase values, and the in-phase and quadrature plane (also strangely but convention …

Is the wavefunction a real physical wave or only a mathematical abstraction? [closed]
Does interaction with physical slits in a double slit experiment indicate that the wavefunction is a real physical wave, as opposed to a mathematical abstraction? This question pertains to the psi ont …

Superposition of position eigenstates after measurement of position?
John Rennie’s answer applies to discrete eigenstates as well since they are also idealizations. There is no manifest physical existence of a mathematically ideal direction “up,” or any other direction …

Open problem? Square of the wave function $\Psi(x)_{x_o} = \delta(x-x_0)$ of a particle loca...
Most scientists agree there are still some interpretational issues in QM, so it is hard to make unequivocal statements. IMO, point-like single quantum pure states (i.e., Hilbert space "rays") are not …

What's the difference between classical and quantum vector superposition?
One of the more bizarre features of quantum mechanics is quantum superposition of states, which is distinctly different from classical superposition of conventional vectors. Classical superposition re …

Is it correct to say a quantum particle is in both "states" at the same time?
There are few if any unequivocal statements that can be made about interpretations of QM, nearly everything is just someone's opinion. No one really understands what superposed quantum states actually …

Are distributions of position and momentum assumed to be independent in quantum mechanics?
Any real world position measurement result also implicitly includes a momentum measurement. Why? Any measurement of x results in some psi(x), its Fourier transform is psi(p), both are measurement resu …

Why would classical correlation in Bell's experiment be a linear function of angle?
OP, here are the justifications for the cos^2 θ and linear parts of your correlation vs angle graphic:
In the quantum case, the “first” detection (using “first” for illustration even though the detect …
