Recent advances in quantum hardware have highlighted both the importance and the growing feasibility of scaling up quantum systems and distributing entanglement across physically separated qubits. Researchers are pursuing multiple paths toward this goal: on one front, novel hardware platforms (e.g. new qubit technologies) promise to support much larger qubit ...

The sinking of gravitationally unstable lithosphere beneath high-elevation plateaus is proposed to be a key driver of their uplift and is proposed to have occurred across our planet including beneath the Andes Tibet Anatolia Colorado Plateau and Nevadaplano. Where the lithosphere is actively sinking geophysical imaging affords a snapshot of ...
A deep property of quantum field theory is the irreversibility of the renormalization group flow: as we move to longer length scales, the number of relevant degrees of freedom only decreases. In this colloquium, we will show how ideas from quantum information theory provide a new understanding of this irreversibility. ...

A common model of AI suggests that there is a single measure of intelligence, often called AGI, and that AI systems are agents who can possess more or less of this intelligence. Cognitive science, in contrast, suggests that there are multiple forms of intelligence and that these intelligences trade-off against ...

Much of the discourse around AI frames it as an alien and inscrutable intelligence. But in fact our success at creating "real" AI with general capabilities in the 2020s has come not only by taking many pages from computational neuroscience, but by performing large-scale modeling on human language-- the "DNA" ...

Synchronized operation of a large number of similar entities can generate behavior that cannot be expected from single one. This principle combined with the physical concept of coherence in waves enables creation of programmable 3-dimensional focal points that can be used to enable many applications such as wireless energy transfer ...

Achieving climate change mitigation goals will likely require increasing the shares of variable renewable energy (VRE) from around 15% today to at least 70% by mid-century.

While photophoresis, or “light-driven motion,” has long explained how aerosol layers remain aloft in the middle atmosphere, practical applications have only recently been gaining attention. Advances in nanofabrication now allow us to build lightweight structures that can propel themselves upward using photophoretic forces alone. These “photophoretic flyers” can sustain flight ...
