AAWSAP DIRD: Quantum Tomography of Negative Energy States in the Vacuum, January 11, 2011 — Department of War Research Paper
This DIRD examines how negative-energy, or “sub-vacuum,” states in quantum fields might be detected and mapped. Its practical scope is limited to the laboratory-scale measurement of minute quantum effects, though it extrapolates from those effects to consider theoretical relevance to concepts…
Incident Overview
This Defense Intelligence Reference Document was written under the Advanced Aerospace Weapon System Applications Program (AAWSAP), the Defense Intelligence Agency contract run by Bigelow Aerospace Advanced Space Studies, and is dated January 11, 2011. It was declassified and published on September 18, 2026 as part of the sixth tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The released copy carries redactions.
What the government released
This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed.
This DIRD examines how negative-energy, or “sub-vacuum,” states in quantum fields might be detected and mapped. Its practical scope is limited to the laboratory-scale measurement of minute quantum effects, though it extrapolates from those effects to consider theoretical relevance to concepts such as warp drives, wormholes, or gravitational control. By reviewing previously identified laboratory examples such as the Casimir effect and squeezed light states, the report identifies the core technical challenge as mapping their spatial and temporal structures reliably. To address this, it proposes quantum optical homodyne tomography as a method to reconstruct and quantify the vacuum fluctuations associated with these states. The document acknowledges that only microscopic, transient negative-energy effects have been realized in laboratory settings. It remains unknown whether larger or longer-lived distributions of such effects can be generated or stabilized, particularly given the experimentally unresolved constraints imposed by quantum inequalities. Overall, this DIRD functions as a measurement- and diagnostics-oriented review intended to lay experimental groundwork for a far more ambitious, highly speculative negative-energy research agenda.
Primary-source excerpt
Drawn directly from the released document: “A beam splitter is a four-port device not only in the case of two incoming light modes interfering to produce two emerging light modes; a beam splitter is always a four-port device. Even if only one beam is split into two beams, if literally nothing behind the semitransparent mirror is interfering with the incident beam, quantum mechanically this nothing means a vacuum state. The very possibility that the second light mode behind the mirror might be excited makes a difference. The vacuum fluctuations carried by the empty mode (and entering the apparatus via the so-called unused input port of the beam splitter) do cause physical effects.”

This paper was written under the contract set out in AAWSAP Statement of Objectives and AAWSAP Solicitation and Original Order, which defined what AAWSAP was asked to study. Read those first: they explain why a program framed around foreign aerospace threats commissioned papers on subjects this far from any known aircraft.
The case in this archive
This record is a primary source for the Advanced Aerospace Weapon System Applications Program, written up here at length from the contemporary record. The file and the case history are worth reading against each other: the document is narrower and more cautious than the account that grew up around it, which is usually the point.
Status of the case
A Defense Intelligence Reference Document is a literature review, and the government’s own summary asks that it be read as one: a reference and synthesis product rather than original research, released without any implication that the concepts it discusses have been validated. The paper collects and summarises published work. It does not report an observation, test a device, or offer evidence that anything it describes has been built, by the United States or anyone else. That caveat matters most for the papers on warp drives, wormholes, antigravity and negative energy, which survey theoretical proposals that remain speculative and in several cases depend on physics no experiment has shown to exist. AAWSAP was a Defense Intelligence Agency contract, awarded in 2008 to Bigelow Aerospace Advanced Space Studies in Las Vegas, to anticipate foreign aerospace threats decades ahead, and its 38 reference papers show what the program chose to spend its time on. The All-domain Anomaly Resolution Office has made no finding about this document, and none is implied by its release.
