Hardware and chips
Hardware and chips: processors, AI accelerators, memory and semiconductor manufacturing.
- Markov process models qudit leakage levels
The study demonstrates that randomized benchmarking sequences with leakage-level decoherence can be analyzed as a Markov process to characterize physical qubit leakage despite SPAM errors.
- Engineers face unprecedented acceleration in AI hardware complexity
The IEEE Design Program addresses the memory wall bottleneck, teaching engineers how to optimize modern AI chips for resource-constrained edge deployments.
- Average Bell pair generation rate reaches 1.03 kHz
Researchers entangled a barium ion with a silicon-vacancy center in a diamond with 87.9% fidelity and a rate of 1.03 kHz, four times faster than prior photonic links.
- Electron spin-qubit coherence reaches 10 ms
Researchers developed a 3D-printed GHz microwave resonator that maintains electron spin-qubit coherence times on the order of 10 milliseconds.
- Linux x32 ABI reduces RAM consumption by 25%
Using 32-bit pointers on 64-bit systems reduces memory consumption by nearly half and improves performance through better cache utilization. A Mastodon deployment experiment cut memory usage from 650 MB to 350 MB, though widespread adoption requires manual compilation since most software is not pre-packaged for x32.
