I don't believe this is the case. The following search works fine for me
with the OP's properties drawer:
C-c a m TITLE="Quantum Mechanics"

I don't believe the space in property values is meant to indicate
multiple values (i.e., in the same way that ":" separates tags). Here's
an example from the manual:
--8<---------------cut here---------------start------------->8---
* CD collection
** Classic
*** Goldberg Variations
:PROPERTIES:
:Title: Goldberg Variations
:Composer: J.S. Bach
:Artist: Glen Gould
:Publisher: Deutsche Grammophon
:NDisks: 1
:END:
--8<---------------cut here---------------end--------------->8---
That said, one can create ad hoc multivalue properties by using regexps
in property searches.
Best,
Matt
