SUBJECT: Assessing Chinaâs current AI development and forecasting its future technology priorities.
In July 2024, the Atlantic Council Global China Hub (AC GCH) and the Special Competitive Studies Project (SCSP) convened experts and policymakers in the second of a two-part private workshop series to gather insights into Chinaâs technology priorities today and in the future. Participants discussed Beijingâs posture on artificial intelligence (AI) development and deployment today, including the hurdles Chinaâs AI industry faces amid US-China technology competition, as well as Beijingâs policy priorities over the next decade. This memo summarizes insights gathered during the workshop.
In todayâs strategic competition between the United States and China, both countries seek to bolster their nationsâ innovation ecosystems and enhance their ability to develop and deploy breakthrough technologies. The United States is committed to maintaining US technological leadership in the long term, as Secretary of Commerce Gina Raimondo demonstrated at the Reagan National Defense Forum in December 2023, when she stated that âAmerica leads the world in artificial intelligence. America leads the world in advanced semiconductor design, period⊠eâre a couple years ahead of China. No way are we going to let them catch up. We cannot let them catch up.â
A long-standing prediction of quantum electrodynamics is that high-energy photons can scatter off each other. However, this process has yet to be observed because dedicated experiments have an extremely low signal-to-noise ratio. Now Alexander Macleod at the Extreme Light Infrastructure, Czech Republic, and Ben King at the University of Plymouth, UK, have designed an experiment that could achieve a high-enough signal-to-noise ratio to measure the phenomenon [1]. Researchers could use such measurements to derive the values of fundamental constants in quantum electrodynamics and then set constraints on various extensions to the standard model of particle physics.
Conventionally, scientists have looked for evidence of photonâphoton scattering by colliding pairs of laser beams. Macleod and King instead propose colliding three laser beams: an x-ray beam and two high-power optical beams. The two optical beams provide the photons that scatter off each other, and the x-ray beam imparts a momentum kick to the scattered photons. This kick alters the trajectory of the photons and spatially separates them from much of the experimental background. As a result, in the detection region, the signal-to-noise ratio is higher than that of two-beam setups.
Macleod and King consider how their setup could be realized in two currently existing research facilities: the European X-Ray Free-Electron Laser facility in Germany, as part of the planned BIREF@HIBEF experiment, and the SPring-8 Angstrom Compact Free Electron Laser in Japan. They then show how the technology used in these facilities should be sufficient to measure photonâphoton scattering. Macleod says that such a demonstration would be important for researchers working on âhigh-power lasers, strong-field physics, and quantum electrodynamics.â
An asteroid-mass primordial black hole flying near a planet could perturb the planetâs orbit by a detectable amount.
Gravitational-wave signals from black hole mergers could reveal the presence of âgravitational atomsââblack holes surrounded by clouds of axions or other light bosons.
Subrahmanyan Chandrasekhar famously stated that black holes are âthe most perfect macroscopic objects there are in the Universe: The only elements in their construction are our concepts of space and time.â His observation relates to the fact that astrophysical black holes, as described by the Kerr spacetime, can be characterized by just two parameters: mass and spin. However, things might get more complex. Theorists have predicted that if a bosonic field interacts with a Kerr black hole, perturbations in the field can grow to form a cloud around the black hole, creating a âgravitational atom,â in which the bosons surrounding the black hole behave somewhat like the electrons surrounding an atomic nucleus [1] (Fig. 1). Whatâs more, if such a gravitational atom is part of a binary involving a second black hole, excitations and ionization processes akin to those occurring in hydrogen atoms may affect how the black hole binary evolves.
Sharing stories over a cup of coffee; dancing in a group; cheering a football game in a crowd: these everyday rituals are among many different types of shared experiences that help humans develop social cohesion.
Anyone who has ever pet a cat or shuffled their feet across the carpet knows that rubbing objects together generates static electricity. But an explanation for this phenomenon has eluded researchers for more than two millennia.
Recent satellite data reveal that the Konya Basin in the Central Anatolian Plateau of TĂŒrkiye is continually being reshaped over millions of years, according to a new analysis led by Earth scientists at the University of Toronto.
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative termâthe metal is nearly 200,000 degrees Fahrenheit. With the short duration of a high-powered laser pulse, copper shifts from a solid state to a plasma state in an instant before it explodes. Understanding the progression of heat in the copper is an exciting breakthrough in physics relevant to the interior of giant planets and laser fusion fuel cores.
Scientists have discovered that ocean waves may become far more extreme and complex than previously imagined.
