Twin-field quantum key distribution (QKD) across an 830-km fibre

Posted by in categories: computing, encryption, internet, quantum physics, security

By using quantum key distribution (QKD), quantum cryptographers can share information via theoretic secure keys between remote peers through physics-based protocols. The laws of quantum physics dictate that photons carrying signals cannot be amplified or relayed through classical optical methods to maintain quantum security. The resulting transmission loss of the channel can limit its achievable distance to form a huge barrier to build large-scale quantum secure networks. In a new report now published in Nature Photonics, Shuang Wang and a research team in quantum information, cryptology and quantum physics in China developed an experimental QKD system to tolerate a channel loss beyond 140 dB across a secure distance of 833.8 km to set a new record for fiber-based quantum key distribution. Using the optimized four-phase twin-field protocol and high quality setup, they achieved secure key rates that were more than two orders of magnitude greater than previous records across similar distances. The results form a breakthrough to build reliable and terrestrial quantum networks across a scale of 1,000 km.

Quantum cryptography and twin-field quantum key distribution (QKD)

Quantum key distribution is based on fundamental laws of physics to distribute secret bits for information-theoretic secure communication, regardless of the unlimited computational power of a potential eavesdropper. The process has attracted widespread attention in the past three decades relative to the development of a global quantum internet, and matured to real-world deployment through optical-fiber networks. Despite this, wider applications of QKD are limited due to channel loss, limiting increase in the key rate and range of QKD. For example, photons are carriers of quantum keys in a QKD setup, and they can be prepared at the single-photon level to be scattered and absorbed by the transmission channel. The photons, however, cannot be amplified, and therefore the receiver can only detect them with very low probability. When transmitted via a direct fiber-based link from the transmitter to the receiver, the key rate can therefore decrease with transmission distance.

Aptera tests a beta version of its SEV at the track ahead of production later this year

Posted by in categories: solar power, sustainability, transportation

Solar Electric Vehicle (SEV) startup Aptera Motors, recently shared test footage of the beta version of its upcoming SEV. The SEV prototype was seen on a test track alongside the three alpha versions already unveiled by Aptera. The beta version represents Aptera’s last phase before pre-production and deliveries later this year.

Aptera Motors is a mobility startup based in San Diego, California, that specializes in solar electric vehicles (SEVs). Since this is the second iteration of the company intending to bring its flagship SEV to market, it has been a story we at Electrek have been following for quite some time.

After unveiling its new SEV in late 2020 with the same monicker as the company, Aptera Motors has been quite prudent in keeping the public and its growing list of reservation holders in the know about its progress.

Tha Martian: Science Fiction and Science Fact

Posted by in categories: entertainment, space

Wed, Feb 2 at 11:30 AM PST.


Dr Jim Green, NASA Office of the Chief Scientist, looks at the science behind the blockbuster movie: The Martian.

The bestselling book about an astronaut stranded on Mars was brought to life in Ridley Scott’s film, The Martian. Before production started, Ridley called NASA to obtain information about NASA’s plans for human exploration of Mars as well as the science of Mars that would contribute to a realistic look and feel of the film in keeping with the approach laid out in Andy Weir’s book.

Google warns that defamation case ruling will force it to ‘censor’ the internet

Posted by in categories: internet, law

The Guardian reports that the case revolves around George Defteros, a Victoria defense lawyer who previously represented Melbourne gangland figures. He sued Google over claims that its publication of search results showing a 2004 article defamed him.

The article from The Age implied that Defteros had become more than just a lawyer for criminal elements but was also a friend and confidant, crossing professional boundaries. The piece also reported on the murder charges Defteros faced in relation to the killing of three men. Prosecutors withdrew the charges in 2005.

House in The Girl Before informed by minimalist Japanese architecture

Posted by in categories: electronics, habitats

Production designer Jon Henson drew on minimalist Japanese architecture to create a house that acts “like a fourth character” for the set of BBC television series The Girl Before.

Written by British author JP Delaney, The Girl Before is a psychological thriller novel set in a fictional one-bedroom house called One Folgate Street in Hampstead, London.

For the TV series, which was created by BBC and HBO Max, the majority of the interior scenes were filmed last spring in a purpose-built set at Bottle Yard Studios in Bristol, while the house’s exterior was specially built.

Circa 2018 o.o!


It’s shiny, fast and ultrapowerful. But it’s not the latest Alfa Romeo. A physics laboratory in Tennessee just unveiled Summit, likely to be named the world’s speediest and smartest supercomputer.

Perhaps most exciting for the U.S.? It’s faster than China’s.
