Single-photon nonlinearity at room temperature
Posted by Saúl Morales Rodriguéz in categories: energy, nanotechnology, quantum physics
Nonlinearity induced by a single photon is desirable because it can drive power consumption of optical devices to their fundamental quantum limit, and is demonstrated here at room temperature.
The recent progress in nanotechnology1,2 and single-molecule spectroscopy3–5 paves the way for emergent cost-effective organic quantum optical technologies with potential applications in useful devices operating at ambient conditions. We harness a π-conjugated ladder-type polymer strongly coupled to a microcavity forming hybrid light–matter states, so-called exciton-polaritons, to create exciton-polariton condensates with quantum fluid properties. Obeying Bose statistics, exciton-polaritons exhibit an extreme nonlinearity when undergoing bosonic stimulation6, which we have managed to trigger at the single-photon level, thereby providing an efficient way for all-optical ultrafast control over the macroscopic condensate wavefunction. Here, we utilize stable excitons dressed with high-energy molecular vibrations, allowing for single-photon nonlinear operation at ambient conditions.

IC Shortage Keeps Linux Out Of Phone Charger, For Now
Posted by Genevieve Klien in categories: computing, mobile phones
We’ve been eagerly following the development of the WiFiWart for some time now, as a quad-core Cortex-A7 USB phone charger with dual WiFi interfaces that runs OpenWrt sounds exactly like the sort of thing we need in our lives. Unfortunately, we’ve just heard from [Walker] that progress on the project has been slowed down indefinitely by crippling chip shortages.
At this point, we’ve all heard how the chip shortage is impacting the big players out there. It makes sense that automakers are feeling the pressure, since they are buying literally millions of components at a clip. But stories like this are a reminder that even an individual’s hobby project can be sidelined by parts that are suddenly 40 times as expensive as they were when you first put them in your bill of materials.
In this particular case, [Walker] explains that a power management chip you could get on DigiKey for $1.20 USD a few months ago is now in such short supply that the best offer he’s found so far is $49.70 a pop from an electronics broker in Shenzhen. It sounds like he’s going to bite the bullet and buy the four of them (ouch) that he needs to build a working prototype, but obviously it’s a no go for production.

Conti Ransomware Expands Ability to Blow Up Backups
Posted by Genevieve Klien in category: cybercrime/malcode
The Conti ransomware gang has developed novel tactics to demolish backups, especially the Veeam recovery software.
Good at identifying and obliterating backups? Speak Russian? The notorious Conti ransomware group may find you a fine hiring prospect.
That’s according to a report published on Wednesday by cyber-risk prevention firm Advanced Intelligence, which details how Conti has honed its backup destruction to a fine art – all the better to find, crush and kill backed-up data. After all, backups are a major obstacle to encouraging ransomware payment.

What China’s New Data Rules Mean for Tesla and Other Auto Makers | WSJ
Posted by Genevieve Klien in categories: information science, sustainability, transportation
China’s new rules on auto data require car companies to store important data locally.
Cars today offer high-tech features and gather troves of data to train algorithms. As China steps up controls over new technologies, WSJ looks at the risks for Tesla and other global brands that are now required to keep data within the country. Screenshot: Tesla China.

Cadillac axes Escalade’s hands-free driving feature due to chip shortage
Posted by Genevieve Klien in categories: computing, transportation
The wider Super Cruise rollout is on pause.
The 2022 Cadillac Escalade will no longer come with the company’s hands-free driving system, Super Cruise, because of the ongoing global chip shortage. Cadillac is suspending the feature on other new vehicles, too.

Using AI and old reports to understand new medical images
Posted by Gemechu Taye in categories: biotech/medical, health, robotics/AI
Getting a quick and accurate reading of an X-ray or some other medical images can be vital to a patient’s health and might even save a life. Obtaining such an assessment depends on the availability of a skilled radiologist and, consequently, a rapid response is not always possible. For that reason, says Ruizhi “Ray” Liao, a postdoc and a recent Ph.D. graduate at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), “we want to train machines that are capable of reproducing what radiologists do every day.” Liao is the first author of a new paper, written with other researchers at MIT and Boston-area hospitals, that is being presented this fall at MICCAI 2,021 an international conference on medical image computing.
