Why is quantum mechanics discrete?

Quantum mechanics is discrete to the extent that action is quantised in units of h. This leads to things like discrete energy levels in atomic energy levels, molecular vibrations etc. However, action involves two variables, and varying one leads to a corresponding variation in the other.

Is quantum physics discrete?

Quantum mechanics is ultimately continuous, not discrete.

Are quantum fields discrete or continuous?

According to our best laws of physics, the fundamental building blocks of Nature are not discrete particles at all. Instead they are continuous fluid-like substances, spread throughout all of space. We call these objects fields.

Are quantum fields discrete?

While the state space of a single quantum harmonic oscillator contains all the discrete energy states of one oscillating particle, the state space of a quantum field contains the discrete energy levels of an arbitrary number of particles.

What happens when space is discrete?

But according to some models, the discreteness should affect how particles move through space. It is a miniscule effect, but it adds up for particles that travel over very long distances. If space-time is discrete, there should be imperfections.

Is QFT proven?

Yes, quantum field theory (QFT) has been proven many many times. It is the most accurate theory in all science. It began in 1948 as an attempt to explain the anomalous magnetic dipole moment of the electron in a mathematically consistent way. It succeeded extremely well.

Is it possible to create Teleport?

While human teleportation currently exists only in science fiction, teleportation is possible now in the subatomic world of quantum mechanics — albeit not in the way typically depicted on TV. In the quantum world, teleportation involves the transportation of information, rather than the transportation of matter.
