Quantum computers hold the promise of performing certain tasks that are intractable even on the world’s most powerful supercomputers. In the future, scientists anticipate using quantum computing to emulate materials systems, simulate quantum chemistry, and optimize hard tasks, with impacts potentially spanning finance to pharmaceuticals.

However, realizing this promise requires resilient and extensible hardware. One challenge in building a large-scale quantum computer is that researchers must find an effective way to interconnect quantum nodes—smaller-scale processing nodes separated across a computer chip. Because quantum computers are fundamentally different from classical computers, conventional techniques used to communicate electronic information do not directly translate to quantum devices. However, one requirement is certain: Whether via a classical or a quantum interconnect, the carried information must be transmitted and received.

To this end, MIT researchers have developed a quantum computing architecture that will enable extensible, high-fidelity communication between superconducting quantum processors. In work published in Nature Physics, MIT researchers demonstrate step one, the deterministic emission of single photons—information carriers—in a user-specified direction. Their method ensures quantum information flows in the correct direction more than 96 percent of the time.

Is the Director General of the Pacific Community (SPC — https://www.spc.int/about-us/director-general) which is the largest intergovernmental organization in the Pacific and serves as a science and technology for development organization owned by the 26 Member countries and territories in the Pacific region.

SPC’s 650 member staff deliver services and scientific advice to the Pacific across the domains of Oceans, Islands and People, and has deep expertise in food security, water resources, fisheries, disasters, energy, maritime, health, statistics, education, human rights, social development and natural resources.

Dr. Minchin previously served as the Chief of the Environmental Geoscience Division of Geoscience Australia, and has an extensive background in the management and modelling of environmental data and the online delivery of data, modelling and reporting tools for improved natural resource management. He has a long track record of conceiving, developing and delivering transformational and innovative projects in the Environmental and Natural Resource Management domains.

Dr. Minchin has represented Australia in key international forums and was Australia’s Principal Delegate to both the UN Global Geospatial Information Management Group of Experts (UNGGIM) and the Intergovernmental Group on Earth Observations (GEO).

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.
