Nature Communications features an article titled, “A physical zero-knowledge object-comparison system for nuclear warhead verification.” The research was led by members of our CVT team including Sébastien Philippe, Robert J. Goldston, Alexander Glaser, & Francesco d’Errico.
Zero-knowledge proofs are mathematical cryptographic methods to demonstrate the validity of a claim while providing no further information beyond the claim itself. The possibility of using such proofs to process classified and other sensitive physical data has attracted attention, especially in the field of nuclear arms control. Here we demonstrate a non-electronic fast neutron differential radiography technique using superheated emulsion detectors that can confirm that two objects are identical without revealing their geometry or composition. Such a technique could form the basis of a verification system that could confirm the authenticity of nuclear weapons without sharing any secret design information. More broadly, by demonstrating a physical zero-knowledge proof that can compare physical properties of objects, this experiment opens the door to developing other such secure proof-systems for other applications.
CVT Graduate Associate, Jayson Vavrek, is featured in an MIT NSE article on his efforts with turning praticle detectors into weapons detectors.
Nuclear Science and Engineering PhD student Jayson Vavrek applies his particle physics to solve problems with nuclear weapons disarmament.
Department of Nuclear Science and Engineering (NSE) graduate student Jayson Vavrek got his start in high-energy particle physics, looking for the smallest forms of matter in the universe. Now at MIT, he uses the same tools and principles to verify nuclear weapons.
The system Vavrek is developing, along with his advisor Areg Danagoulian, Assistant Professor of NSE, is called physical cryptography.

Researchers develop a ‘physical cryptography’ for secure and accurate accounting of the world’s nuclear arsenals
Verifiably reducing the number of nuclear weapons in the world will require more than international diplomacy; a scientific breakthrough is needed. To date, all nuclear arms control treaties have been limited in a peculiar way: Participants cannot determine that the warheads of other countries being counted are real.
Are You Radioactive?
Shaun Clarke, CVT Assistant Director, with CVT students put on a workshop for middle school students and their families about the basics of radiation titled “Are you radioactive?”. Participants learn how to see and measure radiation, one of the most powerful and mysterious forces in the universe. Activities included building a radiation detector using everyday household objects to observe the natural radiation that is all around us.

January 6 Explosion in North Korea
University of Michigan and other university scientists, part of the Consortium for Verification Technology (CVT), are studying the January 6, 2016 explosion in North Korea. The initial analysis of seismic signals performed by Paul Richards and Won-Young Kim at Columbia University’s Lamont-Doherty Earth Observatory found that this event is comparable in magnitude to those from the May 2009 and February 2013 nuclear weapons tests in North Korea (the October 2006 test is widely regarded as a fizzle). Richards and Kim are quoted in an article by CNBC. Other scientists have independently validated this conclusion. Regarding the North Korean claim that it has tested a thermonuclear weapon, CVT scientist Frank Von Hippel of Princeton says: “the seismic magnitude appears to be in the same range as the 2013 test, which was estimated to be of the order of 10 kilotons, it was not in the yield range that we usually associate with thermonuclear tests.” CVT scientist Alexander Glaser, also of Princeton, adds: “If radionuclides have been (or will be) vented from the underground test site, then nuclear forensic analysis may be able to substantiate or challenge North Korea’s claim about the nature of the device. “
CVT scientists Milton Garces (University of Hawaii) and John Lee (University of Michigan) are in the process of obtaining infrasound and radionuclide data, respectively, from the International Monitoring System. These data, together with the seismic data, will provide excellent research and educational opportunities for the faculty and students in the CVT.

IAEA safeguards inspector at a gas centrifuge uranium enrichment plant
In this video, we follow an IAEA safeguards inspector at a gas centrifuge uranium enrichment plant in the Netherlands. Uranium enrichment, a process in which the proportion of fissile U-235 isotopes is increased from 0.71% to up to 6% for industrial use, is an essential step in the preparation of nuclear fuel. However, the nuclear material and technology at enrichment plants can also be used to manufacture weapons grade uranium (over 85%). The IAEA verifies that all nuclear material and activities are declared by the State, and that no nuclear material is diverted from peaceful purposes.
In the film, the inspector explains and demonstrates how she collects samples, checks inventories, and verifies enrichment levels – all to ensure that material is not being diverted to nuclear weapons or other nuclear explosive devices. Inspectors, equipment, techniques and technologies are critical components of IAEA safeguards.
Student Feature: Ruaridh Macdonald, CVT Associate
“Energy is incredibly fundamental to life,” MIT graduate student Ruaridh Macdonald says. “That’s why I keep studying it.”
This tenet has been the thread throughout Macdonald’s nearly eight years at MIT — first as an undergraduate, then as a master’s student, and now as a PhD student — all spent studying nuclear science and engineering. Though he has remained engaged in this one department, he’s participated in a variety of projects, first studying reactor design as he pursued his master’s degree and now working on a nuclear weapons verification project in the Laboratory for Nuclear Security and Policy.

The Consortium for Verification Technology was successful in organizing the first university-led radiation measurement campaign at the Device Assembly Facility at the Nevada National Security Site. The goal of the experiments was to characterize the performance of three unique radiation imaging systems in the presence of large quantities of special nuclear material including 4.5 kg of weapons grade plutonium and 13 kg of highly enriched uranium. The systems included a dual-particle scatter camera and a photon scatter and coded-aperture camera from the University of Michigan. The third imaging system was a coded-aperture neutron imaging system being developed at Oak Ridge National Laboratory. The week-long experiments provided excellent benchmark data and operational experience for each imaging system with sources that are not typically accessible to researchers. Four University of Michigan students took part in the experiments.
