How a novel radio frequency control system enhances quantum computers

Posted by in categories: computing, quantum physics

A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit controls at room temperature. They built a series of compact radio frequency (RF) modules that mix signals to improve the reliability of control systems for superconducting quantum processors. Their tests proved that using modular design methods reduces the cost and size of traditional RF control systems while still delivering superior or comparable performance levels to those commercially available.

Their research, featured as noteworthy in the Review of Scientific Instruments and selected as a Scilight by the American Institute of Physics, is and has been adopted by other quantum information science (QIS) groups. The team expects the RF modules’ compact design is suitable for adaptation to the other qubit technologies as well. The research was conducted at the Advanced Quantum Testbed (AQT) at Berkeley Lab, a collaborative research program funded by the U.S. Department of Energy’s Office of Science.

As the U.K. nears elimination of cervical cancer, the U.S. isn’t close

Posted by in categories: biotech/medical, health

A decade ago, a London cancer prevention researcher predicted that the United Kingdom’s national HPV vaccination campaign would take more than 15 years to prevent a majority of cervical cancers. So when he analyzed the data this year, he was stunned to find that the vaccine may already have nearly eliminated cervical cancer in the U.K. among young women.

“If this is right,” Peter Sasieni of King’s College London said of his findings, cervical cancers “could be reduced to about 50 – just 50 cancers in the whole of the U.K. for women under 30. It’s really quite exciting to see that day come – excitement and just joy.”

That joy was tempered with envy in the United States, where some of Sasieni’s peers lamented that the HPV vaccination rate for teenage girls lags far behind — about 59% in the U.S. vs. more than 85% in the U.K. The analysis, published last week in the Lancet, suggests the U.K. has notched a major public health victory against cancer through vaccinating the vast majority of young women against HPV, said Allison Kempe, a pediatrics professor at the University of Colorado School of Medicine who did not work on the study.

Health Canada adds autoimmune disorder warning to AstraZeneca, J&J COVID-19 vaccines

Posted by in categories: biotech/medical, health

Health Canada is updating the labels for the AstraZeneca and Johnson & Johnson COVID-19 vaccines to add immune thrombocytopenia (ITP), an autoimmune condition, as a potential side effect.

In a statement on Tuesday, the agency said very rare cases of ITP have been reported internationally after receiving the Vaxzevria (AstraZeneca) and Janssen (J&J) COVID-19 vaccines.

ITP is a disorder that can cause easy or excessive bruising and bleeding, which results from unusually low blood platelet levels.

Specific Molecular Mechanism that controls the Transition from Acute to Chronic Pain

Posted by in category: biotech/medical

Previously unrecognized control point identified as target for drugs that block transition. A new study led by University of California, Irvine researchers is the first to reveal the specific molecular mechanism that controls the transition from acute to chronic pain, and identifies this mechanism as a critical target for disease-modifying medicines.

Findings from the study, titled “NAAA-regulated lipid signaling governs the transition from acute to chronic pain,” published today in Science Advances, show that disabling N-acylethanolamine acid amidase (NAAA) — an intracellular enzyme-in the spinal cord during a 72 hour time window following peripheral tissue injury halts chronic pain development in male and female mice.

“Delineating the nature, localization and timing of the events involved in pain chronicity is necessary to pinpointing control nodes in the process that can be targeted by new classes of disease-modifying medicines beyond analgesics,” said Daniele Piomelli, Distinguished Professor in the UCI School of Medicine Department of Anatomy & Neurobiology. “This study is the first to identify that NAAA, a previously unrecognized control node, can be effectively targeted by small-molecule therapeutics that inhibit this enzyme, and block the transition from acute to chronic pain.”

NVIDIA’s new AI brain for robots is six times more powerful than its predecessor

Posted by in categories: biotech/medical, robotics/AI, supercomputing, virtual reality

NVIDIA has launched a follow-up to the Jetson AGX Xavier, its $1,100 AI brain for robots that it released back in 2018. The new module, called the Jetson AGX Orin, has six times the processing power of Xavier even though it has the same form factor and can still fit in the palm of one’s hand. NVIDIA designed Orin to be an “energy-efficient AI supercomputer” meant for use in robotics, autonomous and medical devices, as well as edge AI applications that may seem impossible at the moment.

The chipmaker says Orin is capable of 200 trillion operations per second. It’s built on the NVIDIA Ampere architecture GPU, features Arm Cortex-A78AE CPUs and comes with next-gen deep learning and vision accelerators, giving it the ability to run multiple AI applications. Orin will give users access to the company’s software and tools, including the NVIDIA Isaac Sim scalable robotics simulation application, which enables photorealistic, physically-accurate virtual environments where developers can test and manage their AI-powered robots. For users in the healthcare industry, there’s NVIDIA Clara for AI-powered imaging and genomics. And for autonomous vehicle developers, there’s NVIDIA Drive.

The company has yet to reveal what the Orin will cost, but it intends to make the Jetson AGX Orin module and developer kit available in the first quarter of 2022. Those interested can register to be notified about its availability on NVIDIA’s website. The company will also talk about Orin at NVIDIA GTC, which will take place from November 8th through 11th.

Look: Largest-ever catalog of gravitational-wave events

Posted by in categories: cosmology, physics

In 2,015 researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) captured the first direct evidence of gravitational waves, more than a century after the phenomenon was first proposed.


Gravitational-wave events have only been detectable for a few years, and a new study shows the remarkable diversity of waves caused by black hole mergers.

Alternative rocket builder SpinLaunch completes first test flight

Posted by in category: space travel

SpinLaunch, a start-up that is building an alternative method of launching spacecraft to orbit, conducted last month a successful first test flight of a prototype in New Mexico.

The Long Beach, California-based company is developing a launch system that uses kinetic energy as its primary method to get off the ground – with a vacuum-sealed centrifuge spinning the rocket at several times the speed of sound before releasing.

“It’s a radically different way to accelerate projectiles and launch vehicles to hypersonic speeds using a ground-based system,” SpinLaunch CEO Jonathan Yaney told CNBC. “This is about building a company and a space launch system that is going to enter into the commercial markets with a very high cadence and launch at the lowest cost in the industry.”

This New AI Can Change Your Accent Mid-Conversation

Posted by in categories: business, employment, robotics/AI

In today’s multicultural society, language is the biggest barrier between the employer and the employee. And now as more opportunities for remote jobs are open, employees’ biggest fear is the language barrier or the different accents that might put them in a tough spot with the company they are applying for. Three Stanford students decided to encounter this problem after one of their own friends lost a customer support job due to his accent.

We decided to help the world understand and be understood, student Andres Perez Soderi, who is one of the founders of the new firm, told IEEE Spectrum. The friend group-turned-partners include a computer science major from China, an AI-focused management science and engineering major from Russia and a business-oriented MSE major from Venezuela.

After extensive research, the group found out that a lot of work had been done for voice conversion for deep fake technology but very little attention was given to accent translation. “We knew about accent-reduction therapy and being taught to emulate the way someone else speaks in order to connect with them. And we knew from our own experience that forcing a different accent on yourself is uncomfortable,” added Soderi. “We thought if we could allow software to translate the accent [instead], we could let people speak naturally.” Hence, in 2020 they started a company called Sanas which specializes in different accent translation.
