  Using T-duality, we will argue that a zero point length exists in the low
energy effective field theory of string theory on compactified extra
dimensions. Furthermore, if we neglect the oscillator modes, this zero point
length would modify low quantum mechanical systems. As this zero length is
fixed geometrically, it is important to analyze how it modifies purely quantum
mechanical effects. Thus, we will analyze its effects on quantum erasers,
because they are based on quantum effects like entanglement. It will be
observed that the behavior of these quantum erasers gets modified by this zero
point length. As the zero point length is fixed by the radius of
compactification, we argue that these results demonstrate a deeper connection
between geometry and quantum effects.
