In Star
Trek, the Heisenberg
compensator (or subspace field compensator) is a component of a
starship's transporter system which was designed to sidestep one of the
most basic laws of quantum physics – Heisenberg's uncertainty
principle. The Heisenberg uncertainty principle states that when
measuring conjugate quantities, which are
pairs of observables of a single elementary particle, increasing the
accuracy of the measurement of one quantity increases the uncertainty
of the simultaneous measurement of the other quantity. The most
familiar of these pairs is the position and momentum. Simply put, the
uncertainty principle states that one cannot know both the position of
a subatomic particle and its momentum to arbitrary precision - it is
impossible to know both where an electron is and where it is going at
the same time.

Star
Trek's transporter is supposed to operate by reading the precise
quantum state of every particle making up the person to be transported,
breaking down that person from their component matter into energy,
"beaming" that energy to the desired location, and recombining this
energy back into their component matter according to the information
gleaned when the precise quantum state was read. However, the Heisenberg uncertainty
principle states (in general terms) that one cannot know the quantum
state of a subatomic particle to arbitrary precision. Heisenberg
compensator therefore allowed the transporter sensors to compensate for
their inability to determine both the position and momentum of the
target particles to the same degree of accuracy and ensure the matter
stream of an individual being 'beamed up' remained coherent during
transport, and no data is lost.
The actual mechanics of how Heisenberg compensators were supposed to
work has never been explained in any Star Trek episode or technical
manual. When asked by Time Magazine in 1994, "How do the Heisenberg
compensators work?" Star Trek designer Mike Okuda famously replied,
"They work just fine, thank you."
In 2007, computer company Sun Microsystems actually launched the Sun
Heisenberg Compensator at the Supercomputing 2007 (SC07) Conference in
Reno, Nevada. This was, however, not an actual product but a video
parodying the incomprehensible marketing techno-jargon used by computer
companies in promoting their products.
