Quantum Physics 2005 Notes-3 Observables – (Chapter 5) Notes 3
... • Observables are physical attributes of a system that can be measured in the laboratory. • In quantum physics, in the absence of a measurement, a microscopic system does not necessarily have values of its physical properties. (A particle does not “have” a position until we measure it. It has a set ...

Note that all the quantum numbers are required to be the same (because we are specifying that the particles are electrons and they are € in the 1s orbital) except the ms quantum numbers, which have to be different for the two electrons in order to satisfy the Pauli Principle.

Transition state theory and its extension to include quantum
... “In view of [its] success, it is unfortunate that the theory [TST] does not enjoy a better understanding and confidence among non-specialists. Some of this difficulty can be traced to the rather unconvincing derivations of the [TST] expression for the rate constant which are found in many physical c ...

Quantum Computations with Polarized Photons
... We have presented a method to perform any quantum computation in a fully optical way, by encoding each qubit in a single photon polarization state. A universal set of gates has been proposed, along with the prescriptions for the generation of the input states and for the retrieval of the final resul ...
