IIRC the space character of a property value must be escaped (%20)
because Org uses the plain space character to separate multiple values
in a property.  So the drawer should look like:

    :PROPERTIES:
    :TITLE: Quantum%20Mechanics
    :AUTHOR: Franz%20Schwabl
    :CATEGORY: Quantum%20Mechanics
    :TAGS: Quantum%20Mechanics Group%20Theory
    :KEYWORD: Quantum%20Mechanics Perturbation Second%20Quantization
    :LOCATION: iTune
    :END:

But now, sadly, that's all we've got.  The search engine can only
search for equal strings (e.g. TITLE="Quantum%20Mechanics") or regular
expression and it does not handle multivalue properties.

Looks like to use the intended functionality someone has to patch Org
mode's tag search to handle multivalue properties.

Best,
