Defense Intelligence Reference Document Quantum Tomography Of Negative Energy States In The Vacuum

Defense Intelligence Agency · 51 pages · text from the file's own layer

This Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 11 January 2011. It was produced in FY 2010 under the Advanced Aerospace Weapons System Applications (AAWSA) Program. It reviews negative, or sub-vacuum, energy found in squeezed light and the Casimir effect, and explains quantum optical homodyne tomography as a way to measure and map that energy in the lab. It proposes balanced homodyne detector arrays that could help detect anomalous aerospace platforms using engineered spacetime propulsion.

Figure 4. Wigner Function for a Vacuum (top) and for a Coherent State (bottom). This
clearly shows that coherent states are just "displaced vacua" (Sect. 11B-3). Optical homodyne
tomography was used to reconstruct the Wigner functions from experimental data (courtesy of Ulf
Leonhardt).
