Launch HN: Flower (YC W23) – Train AI models on distributed or sensitive data
Hey HN - we're Daniel, Taner, and Nic, and we're building Flower (https://flower.dev/), an open-source framework for training AI on distributed data. We move the model to the data instead of moving the data to the model. This enables regulatory compliance (e.g. HIPAA) and ML use cases that are otherwise impossible. Our GitHub is at https://github.com/adap/flower, and we have a tutorial here: https://flower.dev/docs/tutorial/Fl
Multicolour entanglement
In quantum networks using light beams and comprising many nodes, multibeam entanglement between more than two photons is desirable. If achieved and made controllable, such multipartite ...
How Sensors Using Quantum Entanglement Could Improve Earthquake Detection
Seismographs are limited to identifying when a tremor is actually occurring. Quantum entanglement could advance sensor ...

Mitigating errors in superconducting quantum circuits to pave the way for future quantum computers
<div><p><time datetime="00Z" class="datetime">Wednesday, March 22, 2023</time></p> <p>With the quantum age on the horizon, scientists are working to develop quantum computers that will have a processing speed exponentially faster than today’s most advanced supercomputer. Building a useful quantum computer is one of the great engineering challenges of our time. In all implementations, qubits that are reliable, stable, and scalable are essential in this endeavor. </p></div>
New water treatment zaps 'forever chemicals' for good
<div>Engineers have developed a new water treatment that removes 'forever chemicals' from drinking water safely, efficiently -- and for good.</div>
Photosynthesis 'hack' could lead to new ways of generating renewable energy
<div>Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.</div>
Semiconductor lattice marries electrons and magnetic moments
<div>A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.</div>
Surprisingly simple explanation for the alien comet 'Oumuamua's weird orbit
<div>When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar space, cosmic rays converted water to hydrogen in the comet's outer layers. Nearing the sun, outgassed hydrogen gave the tiny comet a kick.</div>
Simulated terrible drivers cut the time and cost of AV testing by a factor of one thousand
<div>The push toward truly autonomous vehicles has been hindered by the cost and time associated with safety testing, but a new system shows that artificial intelligence can reduce the testing miles required by 99.99%.</div>
Is there a multiverse?
<div>Interest in the multiverse theory, suggesting that our universe is just one of many, spiked following the release of the movie "Everything Everywhere All At Once." The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to ultimately stop the destruction of the multiverse.</div>
AI Won’t Kill Our Jobs, It Will Kill Our Job Descriptions—and Leave Us Better Off
The hype around artificial intelligence has been building for years, and you could say it reached a crescendo with OpenAI’s recent release of ChatGPT (and now GPT-4). It only took two months for ChatGPT to reach 100 million users, making it the fastest-growing consumer application in history (it took Instagram two and a half years to gain the same user base, and TikTok nine months). But in Ian Beacraft’s opinion, we’re in an AI hype bubble, way above the top of the peak of inflated expectations
Of course Grover’s algorithm offers a quantum advantage!
I was really, really hoping that I’d be able to avoid blogging about this new arXiv preprint, by E. M. Stoudenmire and Xavier Waintal: Grover’s Algorithm Offers No Quantum Advantage Grover’s algorithm is one of the primary algorithms offered as evidence that quantum computers can provide an advantage over classical computers. It involves an “oracle” (external quantum subroutine) which must be specified for a given application and whose internal structure is not part of the formal scaling
New invention: The oxygen-ion battery
<div>An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.</div>
