This Defense Intelligence Reference Document (DIA-08-1004-004), dated 6 April 2010, was produced by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) Program. It is one of a series of advanced technology reports from FY 2009. It reviews the general relativity physics of traversable wormholes and flat-faced "stargate" solutions for faster-than-light travel. It also covers the exotic negative energy these would need, proposed lab methods for generating it such as the Casimir effect and squeezed vacuum, and the constraints involved.

include models for the super-radiant amplification of photons with particular
emphasis on its dynamics and the optimization of the involved parameters.
Experimental concepts being pursued will try to reveal directly the presence of a
non-empty vacuum by using a specifically designed device to amplify the virtual
vacuum photons and produce real electromagnetic radiation via the parametric
amplification of the vacuum fluctuations in an electromagnetic cavity. The 'amplifier'
is a boundary undergoing an oscillation, and hence radiates energy due to the
dissipative action against the vacuum photons. This line of investigation could serve
as a very useful probe to explore the possibility of generating large fluxes of
negative energy. It may be expected that a laboratory demonstration of the
dynamical Casimir effect will occur before 2012.
• Dirac field states: As described in Section Ill-A, this involves either the
superposition of two single particle electron states or the superposition of two multi-
electron-positron states (Reference 29, 30). This is still a nascent topic of study in
quantum field theory. However, mankind already possesses a great deal of
technology that is dedicated to the manipulation and storage of electrons and
positrons via solid state/condensed matter devices and particle accelerators. This
research topic should be supported in order to establish how it could contribute to
an experimental traversable wormhole program.
• Quantum coherence effects: Other types of quantum coherence effects not already
identified or invented should be theoretically developed and explored for the
possibility of finding new free-field or interacting field configurations that produce a
significant magnitude of negative energy which could be produced by technological
means.
• Detecting Negative Energy in the Lab: In Section IV-C this paper identified
proposals for observing negative energy in outer space and in the laboratory, but
further work is needed to downscale astronomical techniques for use at the lab scale,
and we need to firm up our understanding of how lab detectors will respond to
negative energy in situ. A first step in the latter direction was recently proposed by
Marecki (Reference 79) who generalized the analysis of the output of balanced
homodyne detectors (BHDs). The most important feature of these devices is their
ability to quantify the quantum vacuum fluctuations of the electric field because the
output of BHDs provides information on the one- and two-point functions of
arbitrary states of quantum fields. Marecki computed the two-point function and the
associated spectral density for the ground state of the quantum electric field in
Casimir geometries, and predicts a position- and frequency-dependent pattern of
BHD responses if a device of this type is placed inside a Casimir cavity. The
proposed device allows for the direct detection of quantum vacuum fluctuations and
provides a spatial mapping of the negative energy contained inside the cavity. This
offers a potential new characterization of ground states in Casimir geometries, which
would provide an understanding of the negative energy densities present in some
regions in these geometries.
• Trapping and Storing Negative Energy: Ford and Roman (Reference 10) have only
superficially addressed this topic, and there is very little technical literature that
addresses it fully. A theoretical program to develop the physics and technology of
trapping and storing negative energy will need to be supported, and such a program
should be guided by the use of laboratory detectors such as the one proposed in the
28
