6.845 Quantum Complexity Theory, Lecture 02
... We mentioned before that measuring collapses the state, but what if we could take our quantum state and duplicate it? How would this look like? α |0� + β |1� → (α |0� + β |1�)(α |0� + β |1�) = α2 |00� + αβ |01� + αβ |10� + β 2 |11� Therefore we just need to find some unitary transformation to perform ...

Quantum (wave) mechanics
... A group or packet of matter waves is associated with every moving object. The packet travels with the same velocity as the object does. The waves in the packet have the average deBroglie wavelength h / mv . Even though we can’t visualise what is meant by and so can’t form a mental image of ma ...

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.
