Decoherence and the Transition from Quantum to Classical
... At first glance, the Many Worlds and Copenhagen Interpretations have little in common. The Copenhagen Interpretation demands an a priori “classical domain” with a border that enforces a classical “embargo” by letting through just one potential outcome. The Many Worlds Interpretation aims to abolish ...

Lecture 14: Quantum information revisited Density matrices
... Also similar to before, when we consider a particular quantum system we assume that it has some finite set Σ of associated classical states. We will typically use the term register from now on to refer to abstract physical devices (such as qubits or collections of qubits). Associated with any regist ...

In classical theory, an EM wave striking a free electron should cause the electron to oscillate at the EM wave frequency ...

It was realized by Wigner that in quantum mechanics, time reversal has to be defined in a very special way different from all other symmetries. Time reversal operator is anti-unitary: it ...
