Erwin Schrodinger Quotes

Quantum theory also tells us that the world is not simply objective; somehow it's something more subtle than that. In some sense it is veiled from us, but it has a structure that we can understand.

Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong.

If you aren't confused by quantum physics, then you haven't really understood it

The possibilities that are suggested in quantum physics tell us that everything that we're looking at may not be in fact there, so the underlying nature of being is weird.

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.

Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.

It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.

Spooky action at a distance.

Among the lesser effects of quantum theory are gaping holes in old ideas about causality.

If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.

So the old Copenhagen interpretation needs to be generalized, needs to be replaced by something that can be used for the whole universe, and can be used also in cases where there is plenty of individuality and history.

A careful analysis of the process of observation in atomic physics has shown that the subatomic particles have no meaning as isolated entities, but can only be understood as interconnections between the preparation of an experiment and the subsequent measurement.

If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.

There certainly is a tension between the relativity of simultaneity and non-locality in quantum theory, but it's not strong enough to add up to a falsification of either side by itself.

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

Quantum entanglement is a very intriguing issue, but it is not impossible.

The principle that light can be in two places at the same time is absolutely extraordinary.

We talk about quantum weirdness and things being in two places at once, but it all involves atoms and molecules, stuff we don't normally interact with.

It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent.

There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings.

If I realize that actually there's quantum mechanics happening around us all the time in some macroscopic, interconnected way, then that doesn't change my perception of it, that doesn't change my interaction with it; it just changes how I view my interaction.

Since the founding of quantum mechanics in the 1920s, theoretical physics had nurtured an extremely radical tradition.

When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the form of fiction. Particles really do have the possibility of, in some sense, being in more than one place at one time.

Quantum physics thus reveals a basic oneness of the universe.
