The Battle For Post-Quantum Security Will Be Won By Agility


By Thomas Poeppelmann and Martin Schlaeffer Due to their special features, quantum computers have the disruptive potential to replace existing conventional computers in many applications. They could, for example, calculate simulations of complex molecules for the chemical and pharmaceutical industry, perform complicated optimizations for the automotive and aviation industry, or create new fi... » read more

Variational Quantum Algorithms (VQA)


  Abstract "Applications such as simulating large quantum systems or solving large-scale linear algebra problems are immensely challenging for classical computers due their extremely high computational cost. Quantum computers promise to unlock these applications, although fault-tolerant quantum computers will likely not be available for several years. Currently available quantum device... » read more

Manufacturing Bits: Aug. 17


Scaling qubits Australia is a hotbed of R&D activity, especially in the field of quantum computing. For example, the University of New South Wales (UNSW) in Australia has demonstrated a possible way to control millions of qubits in a silicon quantum chip. Researchers from UNSW Sydney have devised a new three-dimensional dielectric resonator, a technology that could deliver controlled... » read more

Post-Quantum Cryptography


Quantum computing is increasingly seen as a threat to communications security: rapid progress towards realizing practical quantum computers has drawn attention to the long understood potential of such machines to break fundamentals of contemporary cryptographic infrastructure. While this potential is so far firmly theoretical, the cryptography community is preparing for this possibility by deve... » read more

Emergent magnetic monopoles isolated using quantum-annealing computer


Using D-Wave’s quantum-annealing computer, Los Alamos National Laboratory has shown that it’s possible to isolate magnetic monopoles. This research could one day enable future nanomagnets.   Abstract: "Artificial spin ices are frustrated spin systems that can be engineered, wherein fine tuning of geometry and topology has allowed the design and characterization of exotic eme... » read more

The Great Quantum Computing Race


Quantum computing is heating up, as a growing number of entities race to benchmark, stabilize, and ultimately commercialize this technology. As of July 2021, a group from China appears to have taken the lead in terms of raw performance, but Google, IBM, Intel and other quantum computer developers aren’t far behind. All of that could change overnight, though. At this point, it's too early t... » read more

Where Imperfections Lead To Opportunity


By Evelyn Hu It is natural to hold a bias that assumes that the highest-quality devices are those formed from the most perfect materials (crystalline, well-ordered, stoichiometric). Therefore, it is ironic, and perhaps counterintuitive, that particular kinds of defects, such as vacancies (missing atoms) in semiconductor materials, can form the building blocks of a new quantum information tec... » read more

Security In FPGAs And SoCs


Chip security is becoming a bigger problem across different markets, with different emerging standards and more sophisticated attacks. Jason Moore, senior director of engineering at Xilinx, talks with Semiconductor Engineering about current and future threats and what can be done about them. » read more

Manufacturing Bits: Feb. 16


Hybrid bonding consortium for packaging A*STAR’s Institute of Microelectronics (IME) and several companies have formed a new consortium to propel the development of hybrid bonding technology for chip-packaging applications. The group, called the Chip-to-Wafer (C2W) Hybrid Bonding Consortium, includes A*STAR’s IME organization, Applied Materials, ASM Pacific, Capcon, HD MicroSystems, ONT... » read more

The Chip Industry’s Next-Gen Roadmap


Todd Younkin, the new president and chief executive of the Semiconductor Research Corp. (SRC), sat down with Semiconductor Engineering to talk about engineering careers, R&D trends and what’s ahead for chip technologies over the next decade. What follows are excerpts of that conversation. SE: As a U.S.-based chip consortium, what is SRC's charter? Younkin: The Semiconductor Research... » read more
