QUANTUM SUPERPOSITION PRINCIPLE
... As a classical system, we might use the state of this system to store a number between 0 and k−1. The superposition principle says that if a quantum system is allowed to be any one of number of different states then it can also be placed in a linear superposition of these states with complex coeffic ...

In quantum mechanics instead, the wave function extends in the classically forbidden region as well, so there is a certain probability to find the particle in this region. Thi ...

Bohr–Einstein debates
The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science. An account of the debates was written by Bohr in an article titled ""Discussions with Einsteinon Epistemological Problems in Atomic Physics"". Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is absolutely central to our modern understanding of the physical world. The consensus view of professional physicists has been that Bohr proved victorious, and definitively established the fundamental probabilistic character of quantum measurement.
