A Quote by Murray Gell-Mann
In fact any experiment that measures a quantum effect is one in which the quantum effect is aligned with the behavior of some heavy, macroscopic object; that's how we measure it.

Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics - this is the reason why quantum mechanics seems so foreign to our everyday existence.
Quantum events have a way of just happening, without any cause, as when a radioactive atom decays at a random time. Even the quantum vacuum is not an inert void, but is boiling with quantum fluctuations. In our macroscopic world, we are used to energy conservation, but in the quantum realm this holds only on average. Energy fluctuations out of nothing create short-lived particle-antiparticle pairs, which is why the vacuum is not emptiness but a sea of transient particles. An uncaused beginning, even out of nothing, for spacetime is no great leap of the imagination.
I'm really fascinated by the parallels between quantum theory and the teachings of some of these ancient texts. So many of the things that quantum physicists are talking about today, like non-locality and the observer effect, are things the yogis have been saying for thousands of years.
The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
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.
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.
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.
We couldn't build quantum computers unless the universe were quantum and computing. We can build such machines because the universe is storing and processing information in the quantum realm. When we build quantum computers, we're hijacking that underlying computation in order to make it do things we want: little and/or/not calculations. We're hacking into the universe.
Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality
When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'
Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child.
This book is unique. I know of no other which so artfully tackles two of the greatest mysteries of modern science, quantum mechanics, and consciousness. It has long been suspected that these mysteries are somehow related: the authors’ treatment of this thorny and controversial issue is honest, wide-ranging, and immensely readable. The book contains some of the clearest expositions I have ever seen of the strange and paradoxical nature of the quantum world. Quantum Enigma is a pleasure to read, and I am sure it is destined to become a classic.
Ancient wisdom and quantum physicists make unlikely bedfellows: In quantum mechanics the observer determines (or even brings into being) what is observed, and so, too, for the Tiwis, who dissolve the distinction between themselves and the cosmos. In quantum physics, subatomic particles influence each other from a distance, and this tallies with the aboriginal view, in which people, animals, rocks, and trees all weave together in the same interwoven fabric.
I once pitched this show that was just like 'Quantum Leap,' in terms of the set-up, and I got a pass because they said 'Quantum Leap' didn't work, even though it was on for six or seven seasons. You can't say 'Quantum Leap' didn't work!
The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer.
