The QSolid project was launched in January 2022 with the aim of building a high-quality #quantumcomputer "Made in Germany" based on superconducting #quantumchips. After 30 months, the large-scale project, led by Frank Wilhelm-Mauch, has reached the mid-term. In the first half of the project, the team of over 160 people from 25 partner institutions was able to develop #keytechnologies for an initial 10-#qubit prototype of the final demonstrator. This created the basis for the implementation, further development and scaling of the system in the remaining course of the project until December 2026. #QSolid focuses on #quantumbits, or #qubits for short, of very high quality with a low error rate. The susceptibility of qubits to errors is currently considered one of the greatest challenges in #quantum computer development. The project envisages a system that contains various quantum processors based on next-generation superconducting circuits with a reduced error rate. More: https://lnkd.in/g38UghSJ /mb

Chiplets are coming to #quantumcomputing. Low Noise Amplifier + Switch + Quantum Dot Array = a pretty impressive demonstration showing the direction of travel for quantum computing. A useful quantum computer is going to need a lot of qubits - so demonstrating we can make the key components using a standard GlobalFoundries process is a pretty killer competitive advantage. Incredible work in this paper from David J. Ibberson, James Kirkman, John Morton, M.Fernando González Zalba made possible by the careful, state-of-the-art cryogenic circuit design led by Alberto Gómez Saiz. The final sentences of these papers always contain wonderful throw-away lines that tell the story: "The result indicates that, with our methodology, high-fidelity readout of silicon spin qubits could be achieved in timescales well below 10 μs, a result that ... fulfills the readout requirements to implement a fault-tolerant quantum computer."

B for #BowandWrap Bow and warp of semiconductor wafers and substrates are measures of the flatness of wafers. One of the key challenges in the development of #VCSEL is the improvement of their operational specifications such as wafer bow and warp.  The aim of the #PhotoGeNIC project is to develop a new VCSEL that meets this challenges, resulting in higher-quality VCSELs that will increase the production yield, reduce the defectivity, and introduce reduced impact on the environment. #photonics #gamechanger #innovation #electronics #HorizonEurope

Our latest paper has not 1, not 2, but 3 novel cryo-CMOS ICs! put together to deliver an all-CMOS quantum dot readout experiment. Using GlobalFoundries 22FDX process we demonstrate critical steps towards the development of integrated silicon quantum processors. On the electronic side, we show a LNA with a noise temperature of 4.2K and a 1<>8 wideband RF Multiplexer with a <1.1dB insertion loss. On the quantum device side, we demonstrate charge sensors with single electron resolution and sensitivity approaching the state-of-the-art. This work perfectly showcases the capabilities of Quantum Motion, spanning the design of cryogenic integrated circuits (Alberto Gómez Saiz), the creation of new test setups and techniques (James Kirkman), the design of quantum structures (M.Fernando González Zalba) and their testing (David J. Ibberson). Above all the work is a testament of the close collaboration between Integrated Circuit Design Engineers and with Quantum Engineers happening in Quantum Motion. https://lnkd.in/eqg2dPwf #quantum #cryocmos

📜 𝗢𝗻 𝘁𝗵𝗶𝘀 𝗱𝗮𝘆 𝗶𝗻 𝟭𝟵𝟰𝟳, John Bardeen, William Shockley, and Walter Brattain demonstrated the transistor at Bell Laboratories in Murray Hill, New Jersey, thus ushering in the era of modern electronics. This tiny device paved the way for the modern electronics era. 𝗧𝗵𝗲 𝗳𝗶𝗿𝘀𝘁 𝘁𝗿𝗮𝗻𝘀𝗶𝘀𝘁𝗼𝗿 was a point-contact transistor, a significant leap from the bulky and less reliable vacuum tubes of the era. Made of germanium, a semiconducting material, it consisted of a thin strip of gold foil with two closely spaced gold contacts. The germanium’s ability to conduct electricity was altered by the electric field generated by the contacts, allowing it to amplify or switch electronic signals 🔌. 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗕𝗿𝗲𝗮𝗸𝘁𝗵𝗿𝗼𝘂𝗴𝗵𝘀 The point-contact transistor operated on the principle of solid-state physics 🔬. It utilized the phenomenon of electron and hole mobility within semiconductors. The key aspect here was its ability to control the flow of electrons through a semiconductor, using a small input voltage to control a larger current. This was a significant improvement over the thermionic emission used in vacuum tubes 💥. 𝗖𝗮𝗽𝗮𝗰𝗶𝘁𝘆 𝗮𝗻𝗱 𝗨𝘁𝗶𝗹𝗶𝘇𝗮𝘁𝗶𝗼𝗻 In terms of capacity, the first transistor could amplify a signal by about 100 times, with a frequency range sufficient for early audio applications 🎶. Its small size, lower heat emission, and reduced power consumption compared to vacuum tubes opened new vistas in electronic design, leading to smaller, more efficient, and more reliable devices 📱. 𝗪𝗼𝗿𝗹𝗱-𝗖𝗵𝗮𝗻𝗴𝗶𝗻𝗴 𝗜𝗺𝗽𝗮𝗰𝘁 The invention of the transistor marked the beginning of the miniaturization of electronic circuits, leading to the development of integrated circuits (ICs) and microprocessors 💾. It revolutionized industries, from telecommunications to computing, and was integral in the space race and the development of the personal computer 🖥️. Today’s transistors are leaps and bounds ahead of the first transistor. Made primarily of silicon, modern transistors can be as small as a few nanometers across – about 10,000 times smaller than a human hair. This miniaturization, enabled by advancements in photolithography and semiconductor processing, allows billions of transistors to be packed into a single microchip. Modern transistors switch and amplify signals at much higher speeds and with greater energy efficiency. They operate in the realm of GHz, suitable for high-speed computing and telecommunications. Moreover, they serve as the building blocks for processors, memory chips, and a myriad of other devices. The first transistor was a foundational innovation that set the stage for the digital age. Its evolution from a rudimentary point-contact device to the highly sophisticated and minuscule transistors of today exemplifies the extraordinary journey of technological advancement 🌟. https://lnkd.in/dBvNRHHa #HistoryofTech #Evolution #DigitalRevolution
