The study was led by Ren Yuanzhen, a researcher with the Beijing Institute of Tracking and Telecommunications, under the PLA’s Strategic Support Force. Coauthors included several senior scientists in China’s defense industry.
Ren and his colleagues could not immediately be reached for comment and it is uncertain to what extent their view represents an official stance of the Chinese military or government.
“A combination of soft and hard kill methods should be adopted to make some Starlink satellites lose their functions and destroy the constellation’s operating system,” said the paper, published in the domestic, peer-reviewed journal Modern Defense Technology.
Scientists realize quantum teleportation between remote, non-neighboring nodes in a quantum network. The network employs three optically connected nodes based on solid-state spin qubits. The teleporter is prepared by establishing remote entanglement on the two links, followed by entanglement swapping on the middle node and storage in a memory qubit.
They demonstrate that once successful preparation of the teleporter is heralded, arbitrary qubit states can be teleported with fidelity above the classical bound, even with unit efficiency. These results are enabled by key innovations in the qubit readout procedure, active memory qubit protection during entanglement generation and tailored heralding that reduces remote entanglement infidelities.
This demonstrates a prime building block for future quantum networks and opens the door to exploring teleportation-based multi-node protocols and applications.
Researchers in Delft have succeeded in teleporting quantum information across a rudimentary network. This first of its kind is an important step towards a future quantum internet. This breakthrough was made possible by a greatly improved quantum memory and enhanced quality of the quantum links between the three nodes of the network. The researchers, working at QuTech—a collaboration between Delft University of Technology and the Netherlands Organisation for Applied Scientific Research (TNO)—are publishing their findings today in the scientific journal Nature.
The power of a future quantum Internet is based on the ability to send quantum information (quantum bits) between the nodes of the network. This will enable all kinds of applications such as securely sharing confidential information, linking several quantum computers together to increase their computing capability, and the use of highly precise, linked quantum sensors.
Starlink has launched a new product meant specifically for RV dwellers and those who can’t wait to get connected to the satellite internet service. While applying for a regular Starlink dish and service will put customers in a waitlist until 2023, Starlink for RVs is immediately available and will ship out to buyers right now. The downside? Network resources are always de-prioritized for it, and the service costs $135, which is $25 more than a regular Starlink connection.
In other words, the RV option costs just as much as a regular Starlink connection with the Portability feature introduced back in March that allows customers to use the service while they’re away from home. A regular connection requires one to have a home service first, though, and that may not be possible for some people. Another difference is that the product for RVs gives customers the ability to pause and un-pause service, so they can control when their billing starts and ends.
Since the network is de-prioritized for the RV service, though, users’ connection might be slow and intermittent in congested areas and during peak hours. “Stated speeds and uninterrupted use of the service are not guaranteed,” the company wrote in its Help page, clearly making sure interested customers understand that it’s prioritizing at-home users. One important thing to note for those looking into the RV option is that they can’t use Starlink while in motion at this time. SpaceX chief Elon Musk also added on Twitter that the dish is too big for cars, though that didn’t stop at least one user from bolting it onto their vehicle’s hood.
Elon Musk said on Monday that he’s testing out SpaceX’s Starlink satellite internet on his private jet.
“I am testing Starlink on the plane. Some polishing needed, but it’s working quite well,” Musk tweeted. He also wrote in the Twitter post that he works while traveling on the jet.
His tweet was part of a Twitter thread about SpaceX president and COO Gwynne Shotwell defending Musk, following sexual misconduct claims involving a flight attendant working on the billionaire’s plane, which Insider first reported on Thursday.
SpaceX announced this week that it is launching a Starlink internet service option designed with RV owners in mind.
The company is rolling out an optional $25 monthly fee for customers who want to relocate their satellite dishes, CNBC’s Michael Sheetz first reported. The extra cost will be added on to the Starlink base service price of $110 per month and will be billed in one-month increments. The users will be able to pause and restart their service at any time.
However, the company says that the internet service will not be active while the RV is in motion and will be limited to an “as-needed basis at any destination where Starlink provides active coverage,” according to a press release.
On large, isolated construction sites, reliable remote operations are a game changer. See how BAM Nuttall remotely deployed Spot for 3D laser scanning using a p… See more.
On a large and remote construction site in Shetland, where the team is battling the elements, covering large distances every day, the Trimble and Boston Dynamics integrated robot solution has become man’s newest four-legged friend.
BAM Nuttall has successfully trialled the integrated Trimble X7 laser scanner with Boston Dynamics’ Spot® robot in a remote construction setting — utilising a private stand-alone 5G network for remote control — in the first use case of its kind.
Enlisting Spot as the newest member of the site team, the four-legged robot has used specially adapted 3D laser scanning equipment to collect data and create site records. Spot and the Trimble X7 payload were controlled remotely using a private 5G communications network covering the 55,176 m2 site, marking the robot’s first 5G deployment in the U.K.
Canada’s government said it would ban the use of the two Chinese telecommunications giants’ 5G gear due to national security concerns. The move follows similar bans in other Western countries.
Microsoft warns of “cryware” malware that steals information and exfiltrate data directly from non-custodial cryptocurrency wallets.
Microsoft is warning of an emerging threat targeting internet-connected cryptocurrency wallets, signaling a departure in the use of digital coins in cyberattacks.
The tech giant dubbed the new threat “cryware,” with the attacks resulting in the irreversible theft of virtual currencies by means of fraudulent transfers to an adversary-controlled wallet.
“Cryware are information stealers that collect and exfiltrate data directly from non-custodial cryptocurrency wallets, also known as hot wallets,” Berman Enconado and Laurie Kirk of the Microsoft 365 Defender Research Team said in a new report.
