The working of a quantum computer is based on the principles of quantum mechanics, an area of physics that deals with the smallest particles in the universe. Physicist Richard Feynman proposed the ...

Quantum effects are the surprising and often counterintuitive phenomena that occur at the nanoscale, where the laws of classical physics break down and the principles of quantum mechanics dominate.

Quantum entanglement—a phenomenon where particles are mysteriously linked no matter how far apart they are—presents a long-standing challenge in the physical world, particularly in understanding its ...
