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.

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.

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.

“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.

The world’s first four-seater electric vehicle can travel up to 250 miles by air on a single charge.

The first fully-functional prototype of the ASKA A5 electric drive and fly Vertical Takeoff and Landing (eVTOL) vehicle was introduced at CES 2023, according to a press release by the firm published on Wednesday.

Traveling 250 miles on a single charge

ASKA A5 is the size of an SUV and the world’s first four-seater electric vehicle that can travel by road and up to 250 miles by air on a single charge.

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.

Yet, it is a small percentage of its workforce.

Amazon.com Inc., one of the largest technology companies in the world with presence in ecommerce, advertising, video streaming and cloud computing, has announced that it will be laying off 18,000 workers as the company copes with the economic downturn in the future, The Wall Street Journal.

Technology companies in the U.S. began laying off people as early as June last year, when Tesla began reducing its staff strength as CEO Elon Musk had a “super bad feeling” about the economy. As the year drew to a close, software-focused companies also announced job cuts, with Meta leading the list with as many as 11,000 employees facing the axe.
