BT and Toshiba have showcased the UK’s first use of secure quantum communication at the telecoms company’s research and development centre in Ipswich.
The showcase demonstrates the use of quantum cryptography for communications over fibre optic cabling. By exploiting the quantum states of photons, the most visible elementary particles in the electromagnetic spectrum, the cryptographic technique can be used to communicate securely over normal fibre cables.
If the Defense Department is looking to implement blockchain, other organizations may quickly follow suit. Blockchain technology helps guarantee that information has a timestamp and recorded whenever any change happens, ensuring data can be trusted in real time. In DARPA’s case, blockchain technology could help track attempted data breaches.
“Whenever weapons are employed … it tends to be a place where data integrity in general is incredibly important,” Booher said. “So nuclear command and control, satellite command and control, command and control in general, [information integrity] is very important.”
In September, DARPA awarded a $1.8 million contract to computer security firm Galois, asking it to verify a specific type of blockchain technology from a company called Guardtime. If the verification goes well, the military could become one of a growing number of industries and institutions using blockchain to help ensure the security of their operations.
Taiwan’s Deputy Minister of National Defense Lee Hsi-ming recently said Taipei is seriously considering organizing its own DARPA to accelerate the research, development and application of military technology.
Lee’s statement, which was made at the 14th annual US-Taiwan Defense Industry Conference in Virginia, followed media reports saying Taiwan lags behind other East Asian countries in establishing a DARPA-like agency. Japan and China have already organized advanced defense research establishments.
Lee’s announcement about establishing a “Taiwanese DARPA,” however, triggered debate among legislators in the country’s parliament, the Legislative Yuan. Critics of the proposed think tank said the proposal for its creation might become a contentious policy item since it will require sharing or distributing funds across agencies.
Since they were first theorized by the physicist Richard Feynman in 1982, quantum computers have promised to bring about a new era of computing. It is only relatively recently that theory has translated into significant real-world advances, with the likes of Google, NASA and the CIA working towards building a quantum computer. Computer scientists are now warning that the arrival of the ultra-powerful machines will cripple current encryption methods and as a result bring a close to the great bitcoin experiment—collapsing the technological foundations that bitcoin is built upon.
“Bitcoin is definitely not quantum computer proof,” Andersen Cheng, co-founder of U.K. cybersecurity firm Post Quantum, tells Newsweek. “Bitcoin will expire the very day the first quantum computer appears.”
The danger quantum computers pose to bitcoin, Cheng explains, is in the cryptography surrounding what is known as the public and private keys—a set of numbers used to facilitate transactions. Users of bitcoin have a public key and a private key. In order to receive bitcoin, the recipient shares the public key with the sender, but in order to spend it they need their private key, which only they know. If somebody else is able to learn the private key, they can spend all the bitcoin.
Not 100 billion galaxies but one trillion. Is this the missing mass then? No more “dark matter”?
The latest finding with the Hubble space telescope:
In Brief:
This newly developed bionic eye sends images directly to the brain to restore a tiny fraction of the pixels a normal eye can produce.
There are about 285 million people in the world who suffer from some type of visual impairment. For many years, researchers have been looking for ways to restore eyesight. This year, Australian volunteers are set to receive bionic eyes which should help restore their vision.
Rocket Lab is dedicating itself to launching small satellites cheaply and efficiently — a capability the American company thinks the burgeoning private spaceflight industry desperately needs.
Small satellites, some no bigger than a lunch box, are revolutionizing how people gather data about the Earth, and they might be the future of global communications.
Rocket Lab’s business model is a bit like Henry Ford’s was when he started selling Model T’s: keep the machine simple, produce a lot of them and keep them affordable. Peter Beck, the company’s owner, told Space.com that he’d like to reach a point where Rocket Lab launches one of its custom-made, small-satellite rockets about once per week. And similar to Henry Ford (who didn’t even want to make different colors of the Model T), Beck said that until that basic goal is met, he has no plans to diversify the company’s services.

In Brief:
NASA has announced that all research it has funded will be FREE and accessible to anyone through their new open portal PubSpace.
NASA is opening up its research library to the public in the newly launched web database PubSpace …and it’s absolutely free.
