A radical of quantum researchers has issued a manifesto urging colleagues to defy what it calls the “militarisation” of quantum science. The authors, who picture themselves arsenic “Quantum Scientists for Disarmament”, accidental they reason subject uses of quantum research, cull subject backing for world work, and privation universities to disclose which quantum projects instrumentality defence money.
The manifesto, uploaded to the arXiv repository connected the web connected January 13, frames its telephone arsenic a effect to wider trends successful rearmament and the dispersed of dual-use technologies, i.e. those that assertion civilian worth portion besides serving defence goals. The radical proposes 4 contiguous steps: to talk arsenic a corporate against subject use, to unit an morals statement wrong the field, to make a forum for acrophobic researchers, and to found a nationalist database listing defence-funded projects astatine nationalist universities.
“We inactive judge that warfare indispensable beryllium utterly rejected arsenic a means of settling planetary disputes, and that bid tin lone beryllium guaranteed by diplomacy, planetary treaties, and cooperation, alternatively than by communal assured destruction,” the manifesto says. “As scientists moving successful a non-neutral probe field, we tin rise our voices toward that aim.”

Military patronage
The researchers reason that quantum physics is nary longer conscionable basal subject and that its subject applications person go evident. These see quantum communications, abstraction and drone sensing, high-precision timing for navigation, and surveillance.
The manifesto says that NATO, for example, has located its quantum physics enactment wrong its broader “emerging and disruptive technologies” docket and released a nationalist quantum strategy summary successful 2024 that described probe successful this tract arsenic an constituent of strategical competition. European institutions person besides described quantum physics arsenic applicable to defence projects, with the European Commission describing quantum sensors arsenic offering show improvements for subject operations.
The manifesto besides says India’s National Quantum Mission works successful “strong collaboration” with the nationalist and backstage defence sectors. Late past month, India’s Chief of Defence Staff released a ‘Military Quantum Mission Policy Framework’ to usher however the equipped forces program to integrate quantum technologies.
Researchers don’t ever spot the defence implications of a task astatine the outset. Even erstwhile partial accusation exists, institutions tin fell it down backing structures and concern vehicles. This is wherefore they accidental they’ve called for a nationalist database, to unit agencies and institutions to beryllium wide astir who funds what, and to trim the country for immoderate actors to contradict their engagement aft a exertion finds its mode into a subject application.
Military patronage has a agelong past successful physics, a tract successful which it has often shaped probe agendas without ever dictating the day-to-day contents of experiments. Quantum physics itself grew retired of attempts successful the aboriginal 20th period to explicate atoms and light, enactment associated with figures specified arsenic Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger. But the 2nd fractional of the period pushed quantum ideas into devices similar atomic clocks, masers and lasers, and semiconductor physics, each of which states treated arsenic strategical technologies.
Accounts of the improvement of quantum electronics and universities’ incentives and organisational structures during the Cold War person paved the mode for debates astir whether specified patronage lone accelerated probe oregon besides changed its direction, and astir however overmuch bureau scientists person retained wrong these backing systems.
The Defense Advanced Research Projects Agency (DARPA) astatine the U.S. Department of Defence is besides famed for straight backing quantum accusation subject for decades.

‘Soft power’
Today, however, quantum physics, cyber security, precocious artificial intelligence, and abstraction systems are each capabilities that governments privation to control, scale, and weaponise, often with the anxiousness that their rivals mightiness bash truthful first.
The manifesto acknowledges that the greater menace isn’t each portion of quantum probe starring to a limb but that defence-linked backing tin reshape the full ecosystem successful the subject establishment’s favour. This is chiefly due to the fact that its backing is stable, which is charismatic for students and universities.
“The enlargement of subject backing for some basal and applied probe connected emerging technologies, including quantum technologies, is not constricted to the world’s large subject powers. In a broader context, this opaque enlargement often takes the signifier of asymmetric military-academic partnerships betwixt the defence departments of almighty nations and world institutions of the Global South,” the manifesto adds.
“This strategy serves arsenic a subtle mechanics done which hegemonic countries enforce their ‘soft’ powerfulness implicit nations of the Global South. For instance, from the position of states that tin walk little of their nationalist wealth connected science, these funds tin enactment projects that would not beryllium executed otherwise, and assistance support pre-existing infrastructure and personnel, appearing arsenic astir irrecusable offers.”
