“I think it is not an exaggeration to say that the realization of the importance of entanglement and the clarification of the quantum description of single objects have been at the root of a second quantum revolution, and that John Bell was its prophet. And it may well be that this once purely intellectual pursuit will also lead to a new technological revolution.”

“John Bell devoted most of his efforts to conceptual and theoretical questions. Would he have liked that I also stress the importance of the technological revolutions that were, and will be, enabled by the conceptual revolutions? I cannot tell, but we know that he started his career in accelerator design, and that he always showed a profound respect for technological achievements. I like to think that he would have loved quantum-jumps-based atomic clocks, as well as entangled qubits.”

“As a witness of that period, I am also deeply convinced that John Bell indirectly played a crucial role in the progress of the application of quantum mechanics to individual objects, microscopic and mesoscopic. The example of his intellectual freedom, that had led to the recognition of the importance of entanglement, was no doubt an encouragement to those who were contemplating the possibility of developing new approaches, beyond the so-efficient paradigm developed decades earlier. His example opened the gate for new quantum explorations.”

“Quantum theory is now discussing instantaneous connections between two entangled quantum objects such as electrons.”

Roger Ebert (1942–2013) American film critic, author, journalist, and TV presenter

Context: Quantum theory is now discussing instantaneous connections between two entangled quantum objects such as electrons. This phenomenon has been observed in laboratory experiments and scientists believe they have proven it takes place. They’re not talking about faster than the speed of light. Speed has nothing to do with it. The entangled objects somehow communicate instantaneously at a distance. If that is true, distance has no meaning. Light-years have no meaning. Space has no meaning. In a sense, the entangled objects are not even communicating. They are the same thing. At the “quantum level” (and I don’t know what that means), everything may be actually or theoretically linked. All is one. Sun, moon, stars, rain, you, me, everything. All one. If this is so, then Buddhism must have been a quantum theory all along. No, I am not a Buddhist. I am not a believer, not an atheist, not an agnostic. I am more content with questions than answers.

“By taking issue with Bell on this score, I am not saying that I am satisfied with my understanding of quantum mechanics. I share Feynman's belief that no one really understands quantum mechanics. But we should not exaggerate our embarrassment; it is ample as it stands. In any event, I agree with Bell that the foundations continue to merit the closest scrutiny.”

Kurt Gottfried (1929) American physicist

Does quantum mechanics carry the seeds of its own destruction? (1991)

“Although quantum theory involves the use of nonlocal states, such as wave packets and entangled states, there is nothing in the theory, or in the real world so far as it is accurately described by quantum theory, that corresponds to the sorts of instantaneous nonlocal influences which have often been thought to arise in the situation envisaged in the EPR paradox, or implied by the fact that quantum theory violates Bell inequalities.”

“I now imagine a quantum theoretician who may even admit that the quantum-theoretical description refers to ensembles of systems and not to individual systems, but who, nevertheless, clings to the idea that the type of description of the statistical quantum theory will, in its essential features, be retained in the future. He may argue as follows: True, I admit that the quantum-theoretical description is an incomplete description of the individual system. I even admit that a complete theoretical description is, in principle, thinkable. But I consider it proven that the search for such a complete description would be aimless. For the lawfulness of nature is thus constituted that the laws can be completely and suitably formulated within the framework of our incomplete description.”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

"Einstein's Reply to Criticisms" (1949)

“The quantum revolution showed us why the old picture of a vacuum as an empty box was untenable.”

John D. Barrow (1952–2020) British scientist

...Gradually, this exotic new picture of quantum nothingness succumbed to experimental exploration... in the form of vacuum tubes, light bulbs and X-rays. Now the 'empty' space itself started to be probed. ...There was always something left: a vacuum energy that permeated every fibre of the Universe.

“On further reflection, I now think that in arguing his case Bell exaggerated, oversimplified the historical development of both classical electrodynamics and quantum mechanics, and as a result arrived at a definition of "understanding" that may be too rigid in that it reflects a presumption - a prejudice, if you will - as to what constitutes physical reality.”

Kurt Gottfried (1929) American physicist

“The actual heart of quantum mechanics is that the objects in its equations are connected to the observations very differently than the classical counterparts have been.”

“The quantum dualities, which are known as S-duality or U-duality, extend the classical T-duality and lead to a beautiful and coherent picture of stringy dualities. These exchange highly quantum situations with semiclassical backgrounds, exchange different branes, etc. As in the classical dualities, among all dual descriptions there is at most one description which is natural because it is semiclassical. All other dual descriptions are very quantum mechanical.”
