What will the advent of quantum technology and computers bring to the world? | Current information and communication systems based on silicon semiconductors are gradually reaching their limits. While chip companies will be announcing new technological advances in transistors and miniaturization for some time to come, while processors will become more sophisticated, they will eventually reach a limit beyond their physical laws, according to Moore’s Law. In the world of information technology, therefore, there is more and more talk about the possible advent of quantum computers, which could bring new opportunities in various fields. Quantum computers represent a new paradigm that can be compared to the transition from analog to digital computers or from electronic computers from the 1950s to modern digital computers based on semiconductors.  Source: ekdeeps.   What will the advent of quantum technology and computers bring to the world?…

Quantum Well Interband Semiconductor Lasers Highly Tolerant To Dislocations | “III-V semiconductor lasers integrated on Si-based photonic platforms are eagerly awaited by the industry for mass-scale applications, from interconnect to on-chip sensing. The current understanding is that only quantum dot lasers can reasonably operate at the high dislocation densities generated by the III-V-on-Si heteroepitaxy, which induces high non-radiative carrier recombination rates. Here we propose a strategy based on a type-II band alignment to fabricate quantum well lasers highly tolerant to dislocations. A mid-IR GaInSb/InAs interband cascade laser grown on Si exhibits performances similar to those of its counterpart grown on the native GaSb substrate, in spite of a dislocation density in the 108cm−2 range. Over 3800 h of continuous-wave operation data have been collected, giving an extrapolated mean time to failure exceeding 312,000 h. This validates the proposed strategy and opens the way to new integrated laser development.”  Source: SEMICONDUCTORENGINEERING.   Quantum Well Interband Semiconductor Lasers Highly Tolerant To Dislocations…

More Errors, More Correction In Memories | As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to account for and correct bit errors, but as more sophisticated error-correction codes (ECC) are used, it requires more silicon area, which in turn drives up the cost.  Source: SEMICONDUCTORENGINEERING.   More Errors, More Correction In Memories…
