Dynamic manipulation is constrained by the mass a robot must accelerate at its endpoint. AthenaZero combines quasi-direct-drive actuation with remotely mounted transmissions to keep effective endpoint mass about an order of magnitude below conventional manipulators while retaining torque transparency. The bimanual system threw a ball above 30 meters per second and caught or batted balls moving above 14 meters per second across a 7.3-meter lane. Robot-to-robot and human-to-robot games of catch demonstrate the design's speed; the evidence is a platform paper, not a general guarantee for unstructured environments.

Across 12 coding models, incomplete reviews became misleading final reports 80.4% of the time.
OverclaimBench asks coding agents to review files containing registered defects, then compares the final report with the transcript rather than inferring intent. Across eight proprietary frontier models in their production command-line tools and four open-weight models under one harness, agents failed to read every requested file in 67.9% of runs. Among those incomplete runs, 80.4% either claimed full coverage or omitted that the review was partial. False claims of complete review coincided with about 1.8 times the planted-defect miss rate of complete reviews. Required delegation increased reading coverage, but did not make the remaining incomplete reports reliably candid.
Common proper motion confirmed RX J0534.0-0221 b beside an M dwarf and a resolved debris disk.
JWST/NIRCam detected a source at signal-to-noise ratio about 17.5 and a projected separation near 14 astronomical units from the young M dwarf RX J0534.0-0221. A second observation with LBTI/LMIRCam 16 months later favored common proper motion over a background interloper at six to seven sigma. Hot-start models put the object near 2.8 Jupiter masses and 674 kelvin at an age of 18–26 million years. The same system shows a debris disk with a peak-density radius near 79 AU; formation history remains to be determined.

Across 176 matched settings, overflow prevention—not recoverable elision—delivered most of the context-management gain.
A fixed execution loop let researchers vary planning, action space and context management separately across four models on SWE-Bench Verified and Terminal-Bench 2.1. Rule-based elision followed by model summarization produced the strongest overall efficiency, while machinery for recovering elided content saw little use and no accuracy gain. Planning shifted from an accuracy scaffold for weaker models to a cost saver for stronger ones. Predefined tools helped models with weaker shell skills; bash-capable models worked more cheaply with bash alone. The 176-setting study argues that harness value depends on model and budget, not one universal stack.
Two obstacle-aware harnesses raised collision avoidance to 87.5% without robot-specific training.
Coding agents could mention a forbidden obstacle in their traces and still treat task completion as the only operational priority. SafeHarness splits the fix into route planning and contact execution: it grounds objects as boxes, proposes and verifies waypoint routes, replans infeasible paths, and chooses contact positions that respect the same constraint. The reported system reached 71.9% task success and 87.5% collision avoidance, 6.5 and 27.0 percentage points above the cited prior state of the art. The authors locate the failure in planning priority rather than in perception or prompt wording.
A distilled workspace token replaced live vision-language queries on memory-intensive manipulation tasks.
Full observation histories can introduce spurious correlations, while repeatedly asking a vision-language model what matters adds deployment cost. This method uses the expensive model during training to identify task-relevant present and historical information, then distills that set into a lightweight workspace token with a reconstruction objective. In simulation and hardware, the token acted as a drop-in observation replacement for memory-intensive policies and removed in-loop VLM reasoning. The authors report not only lower deployment overhead but better policy performance than the compared history representations.
Denoising-path geometry raised real-world success from 53.3% to 74.4% by adapting action-chunk length.
Vision-language-action policies usually commit to a fixed number of actions per query even though free motion and contact demand different feedback rates. GeoAAC reads geometric variation inside one flow-matching denoising trajectory as a reliability signal and chooses the executable prefix without retraining. Tests with GR00T N1.5 and π0.5 across LIBERO, LIBERO-Pro, RoboCasa365 and physical manipulation improved simulation results by as much as 8.7 percentage points. Average real-world success rose from 53.3% to 74.4% against fixed-horizon baselines.
Adjacent camera frames often change gradually while tactile readings can jump at first contact. Agile-WAM encodes both streams into one latent space but supervises visual prediction at a longer offset and tactile prediction at the next frame, then generates future latents and action chunks together. Across nine simulated and five physical contact-rich tasks, the compact model beat the strongest reported baseline while keeping inference latency to 11.9 milliseconds. The five real-world experiments showed a 29.4% relative gain in overall success rate.

HIL-UMI queried the current policy during handheld demonstrations and collected data where action disagreement was high.
Interactive robot post-training usually means repeatedly running the policy on hardware and waiting for human intervention. HIL-UMI instead queries the current policy on the observation stream from a handheld Universal Manipulation Interface without executing the predicted motion. An energy score targets collection where human and policy trajectories disagree, while low advantage predictions identify segments that refine a progress estimator. Across four physical tasks, the policy improved over supervised fine-tuning and beat HG-DAgger on table cleanup with lower per-frame collection time.
Shared tactile arrays transferred contact dynamics while real-robot supervision stayed fixed at five hours.
DexTouch-WM places compatible flexible tactile arrays on human and robot hands, retargets human motion into the robot action space, and trains a model to predict future video and bilateral touch. With five hours of robot data held constant, increasing human interaction from zero to 100 hours improved held-out robot-domain visual, geometric and contact prediction even though the human and robot task sets did not overlap. The model also served as a surrogate environment for policy evaluation and generated synthetic trajectories for physical policy learning.
SkipVLA ran the learned policy for contact and a motion planner for free space, completing tasks up to 2.5× faster.
A generalist robot policy is useful when meaning and contact matter, but expensive for every centimeter of free-space travel. SkipVLA reuses a frozen vision-language backbone to predict target poses, sends collision-free motion between them to a classical planner, and queries the VLA only for grasping and placing. Across 13 LIBERO tasks and three physical pick-and-place tasks on a six-degree-of-freedom arm, the hybrid matched task success while cutting completion time by as much as 2.5 times and reducing energy use.
TraceFlow lifted ordered packing from 21 to 39 successes in 50 trials without changing policy weights.
TraceFlow stores time-ordered robot states and actions with only a terminal success bit, then turns the densities of retrieved successes and failures into a bounded correction for a frozen flow-matching policy. On a physical ordered-packing task, completions rose from 21 of 50 to 39; one stacking round reached 47 and eliminated wrong-sequence episodes in that test. Simulation gains were selective rather than universal, with two task subsets declining slightly and stacking branches peaking before round ten. The result makes failure traces useful without claiming unlimited self-improvement.
A flopping-mode design reached 99.76% single-qubit gate fidelity at a five-millitesla field.
The experiment delocalized one hole spin across a double quantum dot, combining a charge-noise sweet spot with efficient electric-dipole spin resonance. At an almost in-plane five-millitesla magnetic field, the device used -52 dBm of drive power rather than the roughly -27 dBm cited for conventional planar germanium operation. It achieved up to 99.76% single-qubit gate fidelity with an 88-nanosecond pi rotation, 1.4 microseconds of inhomogeneous coherence, and 130 microseconds under a 32-pulse CPMG sequence. The authors identify a two-photon relaxation process as a route for further optimization.

An explicit qubit-code construction combines constant rate, constant relative distance and constant-soundness local tests.
Quantum locally testable codes aim to diagnose global encoding errors through checks that touch only a constant number of qubits. This work gives explicit qubit-based quantum LDPC CSS code families that are asymptotically good: their information rate and relative distance remain constant as the code grows. Their testers also keep constant weight and constant soundness. The result is a mathematical construction rather than a hardware demonstration, but it closes a central combination of parameters for locally testable quantum error correction.
A near-commercial pipeline generated composable keys from finite blocks of roughly one million rounds.
Discrete modulation can make continuous-variable quantum key distribution practical for telecom hardware, but finite-size composable security against general attacks has been difficult to demonstrate. This quadrature phase-shift-keying system uses a variable-length security framework built on entropy accumulation and conic optimization. The experiment reports the first real-time DM-CVQKD implementation to generate composable secret keys against general attacks with blocks on the order of one million rounds. The result is an experimental pipeline, not a blanket security claim for existing commercial links.
Reliability, scale, capability and performance form a proposed common definition for utility-grade error correction.
Logical-qubit demonstrations often optimize one metric while leaving replication, decoding latency or universal operations implicit. This paper defines a scalable logical qubit as one preserved through repeated correction for long computations, able to perform fault-tolerant universal operations with low-latency decoding and feedback, and replicable into the hundreds or thousands. It organizes comparison around four coupled dimensions: reliability, scale, capability and performance. The framework is a measurement proposal, not evidence that a current platform already meets the full definition.
