Wave Photonics’ Post

Dear #quantum community, users, and followers, We have published a new #scientificpublication in the Solid-State Electronics Journal (Volume 215, May 2024, # 108883), co-authored by Dr. Philippe Galy from STMicroelectronics (France) that illustrates some core features of our spin-qubit modeling software QTCAD®. Thank you and congratulations to our 2 authors Dr. Félix Beaudoin and Dr. Pericles Philippopoulos for the tremendous work! This collaborative work with our historic #partner demonstrates how QTCAD® can be used to obtain information about single-qubit gate fidelities in an industrially-compatible 28 nm FD-SOI device, before its fabrication. Notably, we have focused on: >>Computing electron eigenstates in the presence of an inhomogeneous magnetic field; >>Simulating Rabi oscillations using EDSR; >>Bounding the single-qubit gate fidelities by computing the leakage out of the qubit subspace. In this work, we have focused on a single-qubit device. The current version of QTCAD® (v1.3) can also simulate multi-dot systems which makes of it a truly unique tool very useful for quantum device designers and researchers. Do not hesitate to test it. It is free for 30 days and runs on a laptop!

Unveiling the Evolution of Formal Verification in Digital Design! 🧠 Dive into the fascinating journey of formal verification, a critical process ensuring reliability in digital designs, tracing its roots back to groundbreaking milestones in computational logic. In the 1950s, Martin Davis pioneered computer-generated proofs, laying the foundation for formal verification. The late 1960s saw the emergence of first-order theorem provers, revolutionizing computer program verification. During the 1970s, efforts to address theorem proving shortcomings led to the inception of model checking, combining state-space exploration with temporal logic. Randall Bryant's breakthrough in the mid-1980s with ordered binary decision diagrams (OBDDs) revolutionized circuit-level simulation, addressing the challenges of complex designs. The evolution of formal verification methods has led to more efficient, reliable, and trustworthy digital systems, marking a paradigm shift in the semiconductor industry. As Edsger Wybe Dijkstra famously said, "Testing reveals the presence of bugs, not their absence." This underscores the need for innovative approaches like formal verification to ensure robust and dependable verification methodologies. Let's discuss the future of formal verification in digital design! Share your thoughts below. 📣 #SemiconductorIndustry #Semiconductors #FormalVerification

Looking forward to using this feature! It will be quite useful for making reports look great.

Semiwise and sureCore, two innovative companies based in the UK, have recently made significant strides in the field of quantum computing. By utilizing the Spectre tool from Cadence Design Systems, they have successfully tackled critical challenges in developing cryogenic CMOS circuits for quantum computer systems. The collaboration between Semiwise and sureCore focused on modifying transistor models on GlobalFoundries 22FDX using the Cadence Spectre Simulation Platform. This platform is renowned for its capabilities in analog, mixed-signal, and digital circuit simulation and verification at cryogenic temperatures, making it an ideal choice for this cutting-edge project. #electricalengineering #electronics #embedded #embeddedsystems #electrical #computerchips Follow us on LinkedIn to get daily news: HardwareBee - Electronic News and Vendor Directory

Very exited to see this open-source database of superconducting quantum device designs based on #QiskitMetal from Eli Levenson-Falk and team published for the community. SQuADDS: A validated design database and simulation workflow for superconducting qubit design We present an open-source database of #superconducting #quantum device designs that may be used as the starting point for customized devices. Each design can be generated programmatically using the open-source Qiskit Metal package, and simulated using finite-element electromagnetic solvers. We present a robust workflow for achieving high accuracy on design simulations. Many designs in the database are experimentally validated, showing excellent agreement between simulated and measured parameters. Our database includes a front-end interface that allows users to generate ``best-guess'' designs based on desired circuit parameters. This project lowers the barrier to entry for research groups seeking to make a new class of devices by providing them a well-characterized starting point from which to refine their designs.

One major setback of relying too much on commercial software is that it's often a black box, lacking the transparency and control you get from coding to get the solution yourself or conducting the actual experiments. Ask me how I know...or don't 🙄😅 #cad #tcad #simulation #semiconductorindustry

“What is device/compact modeling? How can one explore it as a career?” I had the privilege and pleasure to have Vikram Sekar, PhD on my YT channel. Vikram is the author of a cool newsletter (viksnewsletter.com) that posts about RF engineering and communication technology. Vikram is also a Senior Staff Engineer (Device Modeling) at Qualcomm, San Diego. In the linked video, we discuss about several things including (but not limited to): - Vikram’s career trajectory and over a decade of post-PhD industry experience - Experience with changing thesis supervisor - What does device modeling entail? - Immigration in the US - Growth and outlook about the semiconductor industry Hope you guys have as much fun listening to our chat as we had recording it.

Mixed signal verification is much more than simulating information moving across the analog/digital boundary. For example, one photonics verification challenge is to connect complex digital stimulus to analog circuits interfacing to the photonics circuits. This blog explains why Lightmatter needed this capability and how they implemented it. #verification #mixedsignal #uvm #systemverilog #photonics https://ow.ly/6zR050QVwxU
