Google is hosting a global contest to develop AI that’s beneficial for humanity
Posted by Derick Lee in categories: quantum physics, robotics/AI
The Quantum Flagship was first announced in 2016, and on 29 October, the commission announced the first batch of fund recipients. The 20 international consortia, each of which includes public research institutions as well as industry, will receive a total of €132 million over 3 years for technology-demonstration projects.
One of the most ambitious EU ‘Flagship’ schemes yet has picked 20 projects, aiming to turn weird physics into useful products.

The business of immortality
Posted by Derick Lee in categories: business, life extension
We’ve always wanted to live forever. But in 2019, the pursuit of immortality is big business, and Silicon Valley is at its epicenter. While the new, high-tech war on death is being led by the elite, it could wind up having big consequences for everyone else.

Quantum optical cooling of nanoparticles
Posted by Genevieve Klien in categories: nanotechnology, particle physics, quantum physics
When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature. Researchers at the University of Vienna, the Austrian Academy of Sciences and the Massachusetts Institute of Technology (MIT) are now one step closer to reaching this goal by demonstrating a new method for cooling levitated nanoparticles. They now publish their results in the renowned journal Physical Review Letters.
Tightly focused laser beams can act as optical “tweezers” to trap and manipulate tiny objects, from glass particles to living cells. The development of this method has earned Arthur Ashkin the last year’s Nobel prize in physics. While most experiments thus far have been carried out in air or liquid, there is an increasing interest for using optical tweezers to trap objects in ultra-high vacuum: such isolated particles not only exhibit unprecedented sensing performance, but can also be used to study fundamental processes of nanoscopic heat engines, or quantum phenomena involving large masses.
A key element in these research efforts is to obtain full control over the particle motion, ideally in a regime where the laws of quantum physics dominate its behavior. Previous attempts to achieve this, have either modulated the optical tweezer itself, or immersed the particle into additional light fields between highly reflecting mirror configurations, i.e. optical cavities.

Mark Zuckerberg: The Internet needs new rules. Let’s start in these four areas
Posted by Michael Lance in categories: cybercrime/malcode, internet
I’ve spent most of the past two years focusing on issues like harmful content, elections integrity and privacy. I think it’s important to define what roles we want companies and governments to play in taking on these challenges, so I wrote this op-ed laying out how regulation can help.
Tech nology is a major part of our lives, and companies such as Facebook have immense responsibilities. Every day, we make decisions about what speech is harmful, what constitutes political advertising, and how to prevent sophisticated cyberattacks. These are important for keeping our community safe. But if we were starting from scratch, we wouldn’t ask companies to make these judgments alone.
I believe we need a more active role for governments and regulators. By updating the rules for the Internet, we can preserve what’s best about it — the freedom for people to express themselves and for entrepreneurs to build new things — while also protecting society from broader harms.

An artificial neuron implemented on an actual quantum processor
Posted by Genevieve Klien in categories: information science, quantum physics, robotics/AI
Artificial neural networks are the heart of machine learning algorithms and artificial intelligence. Historically, the simplest implementation of an artificial neuron traces back to the classical Rosenblatt’s “perceptron”, but its long term practical applications may be hindered by the fast scaling up of computational complexity, especially relevant for the training of multilayered perceptron networks. Here we introduce a quantum information-based algorithm implementing the quantum computer version of a binary-valued perceptron, which shows exponential advantage in storage resources over alternative realizations. We experimentally test a few qubits version of this model on an actual small-scale quantum processor, which gives answers consistent with the expected results. We show that this quantum model of a perceptron can be trained in a hybrid quantum-classical scheme employing a modified version of the perceptron update rule and used as an elementary nonlinear classifier of simple patterns, as a first step towards practical quantum neural networks efficiently implemented on near-term quantum processing hardware.

Astronaut bed rest study pays participants $19,000 for 89 days
Posted by Genevieve Klien in category: space
A few days back we talked about a joint NASA and ESA study that was being conducted in Germany looking at long term effects of weightlessness on astronauts and how artificial gravity might help them. More details have surfaced about that study, and it pays very well for doing nothing but laying in bed. The study pays participants $19,000 (16,500 euro) and is known as AGBRESA study 2019.

Women in Science Open House aims to inspire young girls in the STEM field
Posted by Genevieve Klien in category: science
The first Women in Science Open House aims to inspire young women in the STEM field.
Michelle Cash, program coordinator at the Sandy Creek Nature Center, the event has been something she has wanted to do for a long time. After speaking with an intern at the nature center, they realized now is the perfect time because of recent social movements and the increase of women in political power.
“I think this is a good time to recognize and start to make people aware that there’s women out there doing really good stuff for science and has been doing stuff for science for a long, long time,” Cash said.
