David Deutsch Quotes

The qubit acts as a bridge between the microscopic and the macroscopic worlds.

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.

I've always been fascinated by quantum physics and the possibility of alternate realities.

I am fascinated by quantum physics.

The main ingredient of the first quantum revolution, wave-particle duality, has led to inventions such as the transistor and the laser that are at the root of the information society.

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.

I'm fascinated with quantum physics.

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

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.

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future.

If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.

The mathematics of quantum mechanics very accurately describes how our universe works.

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 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.

When I moved to Stanford I began to pursue the line of research I have been following ever since, namely trying to understand the larger implications of fractional quantum hall discovery.

In the future, maybe quantum mechanics will teach us something equally chilling about exactly how we exist from moment to moment of what we like to think of as time.

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.

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

Technologies that may be realized in centuries or millennium include: warp drive, traveling faster than the speed of light, parallel universes; are there other parallel dimensions and parallel realities? Time travel that we mentioned and going to the stars.

Spooky action at a distance.

In subjects that physicists think of as purely quantum, classical ideas and classical computational techniques can often be powerful.

Quantum physics is quite interesting. All these tiny particles are there as much as they're not there. That to me is very, very interesting. And how our thoughts change the outcome of an experiment, I think that's all quite spiritual.

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

We appear to have form, but we are like a whirlpool. We appear to have form, but we are just whirling electrons.
