Science Café Cleveland presents:



Quantum Entanglement:
How "Spooky Action at a Distance" Led to Quantum Computers and Teleportation


April 8, 2019



Harsh Mathur, PhD

Professor of Physics, Case Western Reserve University



Quantum mechanics is the most precisely-tested theory in science. Twentieth century technologies based on quantum mechanics, notably semiconductor electronics and lasers, have changed the way we live. And yet, almost a full century after its initial formulation, quantum mechanics remains a work in progress, and its full technological potential may still not have been realized.

Quantum mechanics is extremely counterintuitive—even to experts, as can be seen from the following quotes by many of its greatest practitioners:

"Anyone who is not shocked by quantum theory has not understood it."
–Niels Bohr, early pioneer of quantum mechanics

"I don't like it, and I’m sorry I ever had anything to do with it."
–Erwin Schrödinger, co-discoverer of quantum mechanics

"No one can say what quantum mechanics means."
–Richard Feynman, leading quantum theorist

"God does not play dice with the universe."
–Albert Einstein, in a letter objecting to the probabilities inherent in quantum mechanics

One of the main sources of puzzlement in what is known as quantum entanglement is memorably described by Einstein as "spooky action at a distance." Another is the principle of superposition, dramatized by Schrödinger in the form of his (in)famous "cat paradox." The past few years have seen remarkable developments in quantum mechanics with new insights, new experiments, and potential new applications, such as quantum teleportation and quantum computing. The old puzzles and paradoxes and the new developments noted above will be the subject of this month's Science Café Cleveland; no prior knowledge of the subject is required.


You can see Professor Mathur lecture on the principles and applications of quantum mechanics in these two Youtube videos.
