Research Bits: May 9


Optical oscilloscope Researchers from the University of Central Florida developed an optical oscilloscope to measure the electric field of light. The high speed at which light oscillates has made reading its electric field challenging, with current instruments able to resolve an average signal associated with a pulse of light rather than individual peaks and valleys within the pulse. “... » read more

Quantitative Study Of Quantum Phase Transitions Key To High-Temp Superconductivity (Lawrence Berkeley Nat’l Lab )


New technical paper "Evidence for a delocalization quantum phase transition without symmetry breaking in CeCoIn5"  led by Lawrence Berkeley National Laboratory in collaboration with UC Berkeley. “The hope is that our work may lead to a better understanding of superconductivity, which could find applications in next-gen energy storage, supercomputing, and magnetic levitation trains,” said f... » read more

QubiC: An Open-Source FPGA-Based Control and Measurement System for Superconducting Quantum Information Processors


Abstract: "As quantum information processors grow in quantum bit (qubit) count and functionality, the control and measurement system becomes a limiting factor to large-scale extensibility. To tackle this challenge and keep pace with rapidly evolving classical control requirements, full control stack access is essential to system-level optimization. We design a modular field-programmable gate a... » read more

Power/Performance Bits: Aug. 24


Low power AI Engineers at the Swiss Center for Electronics and Microtechnology (CSEM) designed an SoC for edge AI applications that can run on solar power or a small battery. The SoC consists of an ASIC chip with RISC-V processor developed at CSEM along with two tightly coupled machine-learning accelerators: one for face detection, for example, and one for classification. The first is a bin... » read more

World’s thinnest magnet Lawrence Berkeley National Laboratory, the University of California at Berkeley and others have developed what researchers say is the world’s thinnest magnet. The one-atom-thin, two-dimensional (2D) magnet could one day pave the way towards new spin electronics or spintronics memory devices and other technologies in the market. Spintronics uses the orientation of... » read more

Week In Review: Design, Low Power


Tools Cadence unveiled Cerebrus Intelligent Chip Explorer, a new machine learning-based tool to drive the Cadence RTL-to-signoff implementation flow. The tool aims to use reinforcement learning to find flow solutions that otherwise might not be explored and applies models to future designs. The company says it can improve productivity up to 10X and PPA up to 20% with optimization of the flow f... » read more

Week In Review: Design, Low Power


Tools Imperas and Valtrix inked a multi-year distribution and support agreement that makes Imperas simulation technology and RISC-V reference models available pre-integrated within Valtrix STING for RISC-V processor verification. The combined solution covers the full RISC-V specification for user, privilege, and debug modes, including all ratified standard extensions, and the near ratified (st... » read more

Week In Review: Design, Low Power


Valens Semiconductor will become a publicly traded company on NYSE as VLN after a merger with PTK Acquisition Corp. Valens provides long-reach, high-speed video and data transmission for the audio-video and automotive industries. The transaction is expected to provide proceeds of approximately $240 million, including up to $115 million in trust from PTK Acquisition Corp. (assuming no redemption... » read more

Zeptosecond measurements A group of researchers have set a new world’s record for the shortest timespan measurement. DESY, Fritz-Haber-Institute and Goethe University Frankfurt have measured how long it takes for a photon to cross a hydrogen molecule. The result? About 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second (10-21 seconds). This is said to be the sh... » read more

Power/Performance Bits: Nov. 3


Wirelessly charging multiple devices Researchers from ITMO University developed a metamaterial that can be used to turn surfaces into wireless charging areas for multiple devices from different manufacturers with different power transfer standards. "There are various wireless power transfer standards with different frequencies, so you can't just use a charger by any manufacturer," said Poli... » read more
