Deterministic Generation of Entangled Photonic Cluster States from Quantum Dot Molecules

Posted by in category: quantum physics

While multiphoton entangled states are the essential building blocks of quantum photonic technologies, large-scale production of such states has proven to be difficult. This study utilizes the unique structure of hole spins in quantum dot molecules to propose an approach that overcomes many of the existing obstacles in the deterministic generation of such states. With high fidelity and production rates that are unmatched among currently available protocols, this proposal seems quite promising as a basis for tomorrow’s optical quantum communication hardware.

Twitter hacked, 200 million user email addresses leaked, researcher says

Posted by in category: cybercrime/malcode

Hackers stole the email addresses of more than 200 million Twitter users and posted them on an online hacking forum, a security researcher said Wednesday.

The breach “will unfortunately lead to a lot of hacking, targeted phishing and doxxing,” Alon Gal, co-founder of Israeli cybersecurity-monitoring firm Hudson Rock, wrote on LinkedIn. He called it “one of the most significant leaks I’ve seen.”

Twitter has not commented on the report, which Gal first posted about on social media on Dec. 24, nor responded to inquiries about the breach since that date. It was not clear what action, if any, Twitter has taken to investigate or remediate the issue.

Meet Voltaire: World’s tallest wind turbine installation ship that’s greater than Eiffel Tower

Posted by in category: sustainability

It will play a key role in constructing the world’s largest offshore wind farm.

Belgian contractor Jan De Nul’s massive Voltaire wind turbine installation vessel (WTIV) is on its way to help build the world’s biggest wind farm, the 3.6GW Dogger Bank in the UK North Sea, according to a press release by the company published last week.

5 Budding Engineers Create Submersible Submarine-Cleaning Drone in Just 6 Weeks

Posted by in categories: drones, engineering

“Five strangers were pulled together” in an engineering challenge to find a solution to a real-world problem.

Engineering researchers of an innovative academy program have designed a Submersible Remotely Operated Vehicle (SROV) in a span of six weeks after accepting the U.K. Navy’s challenge.

“I was skeptical at first that we could pull off such an ambitious project within the timeframe,” said Dylan Brennan, project team lead, a nuclear graduate working for Jacobs.

Earth closest to the Sun, greeted

Posted by in categories: particle physics, space

Nothing personal, the Sun is just going through a phase right now.

On Jan 4, 2023, our planet reached the closest point to the Sun in its orbit and is expected to be hit by the wake of a coronal mass ejection (CME) coming from the Sun, Live Science.

A coronal mass ejection is a large expulsion of plasma and magnetic field from the solar surface. When the particles in this expulsion and the magnetic field interact with the Earth’s atmosphere and magnetic field, it compresses the latter, which is referred to as a geomagnetic storm.
