✨ Celebrating a Milestone in Technology: The 1956 Nobel Prize in Physics ✨   In 1956, the world of science and technology celebrated a groundbreaking achievement that would forever change the landscape of electronic devices. The Nobel Prize in Physics was awarded to three visionary scientists: William Shockley, John Bardeen, and Walter Brattain. Their invention? The transistor - a device that has become the cornerstone of modern electronics.   🎈 The Inventors Behind the Revolution: William Shockley, an American physicist, led the research project on transistors at the Shockley Semiconductor Laboratory in Silicon Valley. His p-n junction theory was pivotal in the development of solid-state electronics. John Bardeen, renowned for his contributions to modern solid-state physics and electronics, played a crucial role in the invention of the transistor alongside his work on superconductivity. Walter Brattain, responsible for the experimental work leading to the transistor's creation, developed techniques essential for its development and commercial application. 🌟 The Invention That Sparked an Era: The transistor, an electronic element for amplifying and controlling electrical signals, marked a significant leap from the bulky, inefficient vacuum tubes of the early 20th century. Its advantages - small size, durability, low power consumption, reliability, and high-frequency operation - opened up new horizons in computing, communication, and a myriad of electronic devices.   🌞 A Legacy That Transforms the World: The transistor's invention catalyzed the rapid advancement of information technology and digital society transformation. It laid the foundation for the intelligent electronic products that have become integral to our daily lives.   ⚡ Shanghai Leiditech's Contribution: In the spirit of innovation that the transistor embodies, Shanghai Leiditech has been at the forefront of integrating transistors into smart products. From compiling industry charts to developing protection schemes for USB2.0 and USB3.0/TYPE-C, Leiditech continues to explore the endless possibilities that transistors offer in circuits and beyond.   #NobelPrize #Physics #Transistor #Technology #Innovation #ElectronicRevolution #SmartDevices #ShanghaiLeiditech

🎉 Congratulations to Antonio Lacerda Santos Neto for the successful defense of his PhD Thesis entitled "Predictive modeling of nanoelectronic devices". The work was supervised by Xavier Waintal and Christoph Groth. This PhD thesis is a cotribution to the control of quantum-mechanical systems in condensed matter, advancing our understanding and development of full-fledged quantum technologies. Their work focused on creating a comprehensive simulation stack, ranging from the microscopic modeling of individual quantum bits and flying qubits to the treatment of many-body correlations with automatic Feynman diagrams calculations, and exploring the collective behavior of multi-qubit devices and quantum error correction codes. A notable achievement of this research is bridging the gap between abstract quantum models and actual physical systems, essential for understanding quantum entanglement and decoherence dynamics. Antonio developed innovative algorithms that simplify models from their microscopic counterparts using renormalization group theory, applied to quantum nanoelectronics and semiconductor circuits. This work addresses long-standing issues like the 0.7 anomaly and modern challenges in building flying qubit architectures. Thanks to Anton Akhmerov, Fabienne Michelini, Rodolfo Jalaber and Hermann Sellier for their participation to the jury. #phdthesis #quantum #quantumtechnologies #quantumcomputing CEA-Irig, Université Grenoble Alpes, Grenoble INP - UGA

Celebrating the 2023 #NobelLaureates in Chemistry, Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov - https://ow.ly/38WH50PSUAI Quantum dots are everywhere in optics. The semiconductor crystals are so small they are governed by quantum size effects. The laureates are honored “for the discovery and synthesis of quantum dots.” Moungi G. Bawendi, Lester Wolfe Professor at Massachusetts Institute of Technology Bawendi leads a research group responsible for developing the most widely used method of quantum dot synthesis. He developed the hot-injection synthesis method for creating quantum dots, which provided a new level of control over the size and optical quality of quantum dots. Louis E. Brus, Samuel Latham Mitchill Professor Emeritus at Columbia University While at Bell Labs, Brus and his team were inspired by the work of Alexei Ekimov and Alexander Efros on quantum dots. He showed in 1983 that nanoparticles floating freely in a fluid—now known as colloidal quantum dots—have a size-dependent quantum effect. Alexei I. Ekimov, Chief Scientist at Nanocrystals Technology Inc. Ekimov performed research at the Vavilov State Optical Institute with semiconductor nanocrystals, eventually discovering quantum dots. He used knowledge of optical techniques in the analysis of doped-glass, to create size-dependent quantum effects in colored glass.

When you're researching with professor David Catlett, PhD, MTS '17, who sometimes moonlights in ministry when not teaching chemistry, don't be surprised if Bible verses crop up on your machine. Students recently built a device on campus to irradiate semiconductor chips. The verse in the concrete comes from the end of Exodus 34 in the Latin Vulgate, when the Israelites see Moses coming from the tabernacle with beams of light shining from his face.

I am happy to be a co-author for "Technology Visions for APL’s Centennial". I am sharing the link to the article that was published as part of APL's Technical Digest. The Johns Hopkins University Applied Physics Laboratory (APL) will celebrate its centennial in 2042, about 20 years from the time of this writing. As the Lab looks toward this milestone, a team comprising APL staff members who are fellows of several premier technical societies or APL master inventors predicted which innovations and technologies might become global trends by 2042 and, consequently, could be considered as potential elements in APL’s science and technology strategy. This article describes their predictions. Here is the link to the article. #johnshopkins #jhuapl #apl
