Quantum measurements are subject to an uncertainty that is usually distributed equally between pairs of complementary properties (such as position and momentum). However, a technique known as 'squeezing' can be used to reduce the uncertainty of one desired property at the expense of increasing that of the other. Squeezing may have a critical role in high precision applications such as atomic clocks and optical communications. This paper demonstrates the ultimate squeezing limit for the polarization of a composite optical system.
