What was needed at this point was a unification of the two accounts of quantum phenomena, namely matrix mechanics and wave mechanics, and a common solution to their difficulties. Even though Schrödinger had published what he took to be a proof o ...

Quantum Wires and Quantum Point Contacts
... non-Ohmic system: the series resistance is much smaller than the sum of the individual QPC resistances One needs quantum mechanics to understand such behavior – after the first QPC the electron beam gets collimated, and then it is prepared to pass through the second QPC without backscattering. ...

Quantum annealing with manufactured spins
... qubit temperature. The key conclusion we draw from Fig. 3b is that our qubit dynamics is best characterized as being quantum mechanical in nature for T=80 mK. The system evolves to its ground state through a process of quantum annealing. But so far we have shown this only for an individual qubit. It ...

Photon emission only occurs when an electron jumps from one stationary state to another of lower energy If the electron exists in stationary states with fixed orbits, then the angular momentum must be quanti ...

Space-Time Approach to Non-Relativistic Quantum Mechanics
... mathematically equivalent to the familiar formulation. In quantum mechanics the probability of an event which can happen in several different ways is the absolute square of a sum of complex contributions, one from each alternative way. The probability that a particle will be found to have a path x(t ...
