ALT An abstract depiction of gravitational waves, shown as black ripples in the background with two intersecting beams in the foreground. Above is a pastel-colored cloud filled with spheres and squiggly lines.

ALT Rectangle diagram titled “All 3D topological phases in K-theory.” A large yellow rectangle represents 2D topological invariants and is divided into three columns: Gapless, TI/TSC, and Atomic states. Inside it is a smaller orange rectangle (1D invariants), with a red-and-orange striped region within labeled "Symmetry indicators.” A small green rectangle (3D invariants) sits on top of the TI/TSC column. A legend on the right identifies each color: red for 0D, orange for 1D, yellow for 2D, and green for 3D invariants.

ALT A two-panel diagram comparing conventional and quantum-enhanced sensing of classical fields. In the top panel, conventional sensing measures a complex field along selected axes, producing separate projections that lose information, or a blurred distribution due to added vacuum noise. In the bottom panel, quantum-enhanced Bell Quantum Signal Learning uses entangled two-mode squeezed states, with one mode probing the field and the other stored as a reference. Beam splitters and homodyne measurements combine the modes to recover multiple properties of the field with greater precision and without choosing a single measurement direction in advance.

ALT Top row: two scanning electron microscope images on a dark blue-green background, each with a white "1 µm" scale bar. Left image labeled "Rough" shows an electrode tip with a jagged edge. Right image labeled "Sharp" shows an electrode tip with a smooth edge. Bottom row: two line graphs plotting conductance G(S) against voltage (mV, from -10 to 10) both labeled "FeTe0.55Se0.4 ." Left graph, labeled “Rough," RN = 106 Ω, shows a red line with a single sharp peak centered at zero voltage. Right graph, labeled "Sharp," RN = 276 Ω, shows a blue line forming a flat-topped plateau between about -2 and 2 mV.

ALT A schematic showing two sets of arrows extending from a central point in 3D space. Black axes extend from the center, and a light gray grid forms a background. Orange arrows on the left are labeled “Tr ρ = 1,” while blue arrows on the right are labeled “Tr ρ = 0.” Each set follows a red triangular path marked with time-evolution expressions. At the bottom in the gridded space are labels “𝒦₀” in orange and “𝒦α” in blue.

ALT Panel (a) consists of a graph plotting the dynamics of kurtosis of rapidity distribution as a function of rescaled time on the x-axis. The graph contains six lines corresponding to V0 = 1 (dark blue), V0 = 2 (medium blue), V0 = 3 (light blue), V0 = 4 (light green), V0 = 5 (medium green), and V0 = 6 (dark green). Panel (b) plots the evolutions of distributions of rapidity on the y-axis, rescaled time on the y-axis, and 𝛳 on the z-axis. HR for V0 = 4 is plotted with a light blue line, and gBBGKY for V0 = 4 is plotted with a dark blue line. Panels (c, e, f) present similar graphs plotting the evolution two-point correlation function. Panel (d) presents a similar graph as panel (a), plotting the dynamics of the kinetic energy function. In all the graphs, dots represent the molecular dynamics of the system while solid lines represent the prediction by gBBGKY.

ALT Six-panel figure on black, arranged in two rows of three. Each panel except top-right shows a purple-to-yellow heatmap with a white parallelogram outline marking the moiré unit cell and a green dot marking a fixed hole position. Some show a single bright glowing blob, others show three bright spots at the parallelogram's corners, and one shows a glow at the center and corner. The top-right panel is a separate schematic with red and blue circles showing electron and hole doping with curved arrows.

ALT A phase map of shock-compressed MgO showing temperature versus pressure for three crystal orientations: [111] shown in red, [110] in blue, and [100] in green. The measurements follow different paths through the B1 and B2 solid phases before converging near complete melting at about 572 GPa and 13,200 K. X-ray diffraction ranges below the plot show orientation-dependent B1-to-B2 transition behavior. An inset compares MgO’s melt curve with those of Ta, Fe, SiO2, diamond, and MgSiO3, showing MgO’s unusually high melting temperature. A top axis relates pressure to estimated core-mantle boundary pressures in super-Earths.

ALT Two diagrams with x-y-z axes show topological charge polarization induced by an external magnetic field in a magnetic AXI, and topological nonlocal spin polarization induced by an external magnetic field in a T-DAXI. Both diagrams show a green cuboid, labeled either “AXI” or “T-DAXI,” with a red arrow labeled either “P” or “Ps,” representing the induced charge polarization, and an external magnetic field, B, both pointing upward. For AXI, positive-charge circles run along the bottom and negative-charge circles run along the top. For T-DAXI, left-pointing arrows, representing “spin sy down,” run along the bottom and right-pointing arrows, representing “spin sy up,” run along the top.

ALT A bell-shaped normal distribution shown in blue–symmetric and peaking at x = α. Below the curve is a series of five green circle clocks with one hand. From left to right, the hand rotates from roughly the 11 o’clock position counter clockwise to roughly 7 o’clock, with 9 o’clock sitting under the bell curve peak. The clocks represent the Bloch state projections of a qubit. The bell curve is a probability distribution of the oscillator position. The spread of ticks in the clock around the target state on the yz-plane of the Bloch sphere illustrates the over- and under-rotations arising from Gaussian position uncertainty.

ALT Diagram illustrating hematite's crystal and magnetic structure across a temperature scale from TM ≈ 255 K to TN ≈ 950 K. Three 3D rhombus-shaped structures are shown side by side, each containing orange spheres (Fe³⁺ ions) connected by gray spheres (O²⁻ ions). Red arrows show spin orientation. A legend identifies the orange and gray spheres. Below, two hexagonal top-down views show red arrows for L and black arrows for M pointing in different directions.

ALT Two diagrams each showing four arrows meeting at a central vertex. On the left, for spin 3/2, the arrows are labeled 1, 1, 1, and 3. On the right, for spin 2, the arrows are all labeled 1.

ALT An illustration of the question of whether subsystems exhibit entanglement when a Haar random state is partitioned into three. A circle is separated into three pie pieces containing six (A), seven (B), and five (C) qubits. Arrows point between two sets of qubits from two different pie components, questioning whether they are entangled.

ALT Three channel circuit diagrams used to illustrate local reversibility. The diagram on the left shows a horizontal rectangular block, labeled ρ, representing an input state, with lines connecting rows of smaller rectangular blocks above it. Each small block represents a gate. One gate is highlighted in orange. In the second diagram, the gate above the orange gate is green and labeled with a “~”. A channel circuit acting on ρ is locally reversible if each of its gates (e.g. the orange gate) is reversible, meaning that the gate’s action upon the state at the time can be reversed locally by some other gate (e.g. the green gate). In the third diagram, both the orange and green gates have been removed. As such, local reversibility is a property of both the circuit and the input state ρ.

ALT A figure depicting how short fibers bend smoothly under increasing flow, while longer fibers suddenly snap into a new position. Figure (a) shows how a short fiber bends smoothly as flow increases; (b) a longer fiber snaps suddenly; (c) a schematic showing the fiber, channel and flow paths; (d–e) graphs comparing smooth bending and snapping across fiber geometries; (f) compares measured and predicted flow rates at the snapping threshold.

ALT A 3D rendering of a Bloch-sphere representation of the cat-qubit manifold.

ALT A large black circle labeled Central Image Plane. It’s filled with a grid of dozens of cavities which look like tiny gray blobs, all neatly arranged in rows. The distance between three blobs is 20 micrometers.

ALT A graph displays several measurements of the out-of-time-order-transport parameters in the Floquet XXZ model, with t on the x-axis and g(t) on the y-axis. A green line plots the function for g0(t), and a blue line plots the function for g0(t) - g2(t). Red and purple dashed lines indicate effective field theory predictions outlined in Table I of the paper.

ALT On the top are three photographs. From left to right, these are labeled “high energy physics,” showing a particle collider, “materials,” showing different types of construction materials, and “chemistry,” showing a group of beakers filled with different colored liquids. Below the three photographs is a downward pointing arrow labeled “model.” It points to text that reads “this work, small efficient circuits.” Below is a circuit schematic showing one bosonic mode in green and one qubit in black. Below is text that reads “standard deep qubit circuits,” showing a more complicated version of the circuit schematic with multiple bosonic modes and qubits.

ALT A temperature-pressure phase diagram, with x-axis labeled “P(GPa)" from 0 to 1 and y-axis labeled “T(K)" from 0 to 4. Two black curves divide the plot into "SC1" (lower left) and "SC2" (upper right) regions, meeting near a dashed line labeled "P*." Six colored dots along the boundary and within SC2 show data points at increasing pressures, from blue (0 GPa) to yellow (0.77 GPa). The plot is shaded with a red-to-white gradient, with darkest red in the upper-right of SC2 and fading to white toward SC1, matching a color bar labeled "c33,F (A.A.)" from 0.0 to 1.0.
