As happened in the past with classical computers, researchers are still searching for a good way to implement quantum computers. It isn't so much that researchers don't know what they want to build; it's more of a question of searching for the right materials to create a scalable quantum computer. The current leader in the field—although I'm sure many would dispute this—uses the currents in loops of superconducting material. This has the advantage of being based on very traditional manufacturing processes. And because it is manufactured, many properties are under design control.

This has led to quite rapid progress, but there has been one limitation: long-distance communication. Quantum computers need to be able to communicate with other quantum computers, even with other parts of the same quantum computer. But superconducting loops all speak to each other in the tones of microwaves, which are low energy and easily disrupted. Now, however, a path to using visible light to transfer quantum information between qubits has opened up. This could revolutionize the development of quantum computers based on superconducting currents.

Loopy qubits

The fundamental unit of information in a quantum computer is a qubit. It's not quite analogous to a bit, which has one of two possible values: a one or a zero. While a qubit has two quantum states that we label as a one and a zero, it is incorrect to think of the qubit storing a one or a zero. It is more correct to think of it as holding a one and a zero.

We’re starting to see what arguments in the Waymo v. Uber trial will look like

Anthony Levandowski may have to plead the 5th again, but in front of a jury.

SAN FRANCISCO—At a hearing that stretched for more than four hours yesterday, lawyers for Waymo and Uber hammered out the final rules that will govern what evidence is presented in their upcoming trial. Here are five questions that both sides view as paramount for getting their side of the story out to the jury.

Before that, here's a quick roundup of the Waymo v. Uber basics. Waymo sued Uber in February, claiming that Anthony Levandowski, a former Google engineer, stole 14,000 files just before he left Google to create his own startup, Otto. Within months, he sold Otto to Uber for $680 million and became the head of Uber's self-driving car project. Levandowski, who is not a defendant in the case, pled the Fifth Amendment rather than answer questions about the allegations. He was fired after he wouldn't comply with court orders related to discovery.

Uber denies any of the trade secrets ever got to its servers, and the company says its self-driving car technology was built independently.

Accused NSA leaker was angry over Fox News always being on in the office

“Yeah, I screwed up royally.”

The NSA might have all sorts of high-tech methods to prevent and sniff out internal leaks. But sometimes all it takes is a pair of pantyhose to steal highly sensitive, classified information.

Consider how the agency was able to pin down an alleged leaker of a classified intelligence report, published by The Intercept, that said Russian military intelligence launched a cyberattack on a US voting software company and sent spear-phishing e-mails to local US election officials ahead of the November election.

NSA investigators quickly narrowed down suspects to Reality Leigh Winner, a 25-year-old linguistics contractor for Pluribus International Corporation, a company that provides analytical, translation, and cyberwarfare development services to the intelligence community. When The Intercept asked the NSA in June to confirm the document's authenticity, the online news agency unwittingly exposed the leak's alleged source. The copy of the report showed fold marks that indicated it had been printed—and it included encoded watermarking that revealed exactly when it had been printed and on what printer.

The Google Assistant comes to Android TV, starting with the Nvidia Shield

Ask it to play your favorite shows, turn off the lights, or pause the TV.

The Google Assistant is rolling out to one more form factor, as Google announced today that Android TV is finally getting its flagship voice command system.

For now, it's only on one device, the Nvidia Shield TV, but Google has said it's also coming to the Sony Bravia TV line in "the coming months." If you're wondering why the service isn't debuting on a Google-made Android TV device, it's because one doesn't exist. Since the end of the Nexus Player's run in 2016, Google hasn't offered a first-party Android TV device.

Voice commands are handled from the remote, which has a microphone built in. Users can either press the mic button and issue a command or just say "OK Google" while the box is on. On Android TV, the Google Assistant specializes in navigation and content searching. You can ask it to play shows by name, and as long as you're subscribed to the right content providers, the shows will just play. There are general remote control commands like "pause" and "unpause," and you also get access to the full suite of other Google Assistant commands, like controlling smart home devices (great for turning off the lights before a movie), asking questions, and accessing third-party voice apps.

EU Proposes Take Down Stay Down Approach to Combat Online Piracy

The European Commission published a set of guidelines today outlining how online service providers should tackle illegal content, including piracy. The recommendation follows the notice-and-stay-down principle, proposing proactive automated filters and measures against repeat infringers.

In recent years, many copyright holders have grown frustrated with pirates copies of their content (re)appearing on hundreds of online platforms.

This problem is not restricted to pirate sites, but also affects other services where users can freely upload content, including Dropbox, Google, YouTube, and Facebook.

In an attempt to streamline these takedown procedures the European Commission published a detailed set of guidelines today. Their communication titled “Tackling Illegal Content Online” includes a comprehensive overview of how illegal content, including piracy, should be dealt with.

The recommendation, of which a non-final copy leaked earlier this month, is non-binding. However, future legislative measures are not ruled out if no significant progress is made.

One of the motivations to release the guidelines is to define clearly what a good takedown policy would look like. A harmonized and coherent takedown approach is currently missing in the EU, the Commission notes.

“A more aligned approach would make the fight against illegal content more effective. It would also benefit the development of the Digital Single Market and reduce the cost of compliance with a multitude of rules for online platforms, including for new entrants,” the recommendation reads.

One of the suggestions that stand out is “proactive” filtering. The Commission recommends that online services should implement measures that can automatically detect and remove suspected illegal content.

“Online platforms should do their utmost to proactively detect, identify and remove illegal content online. The Commission strongly encourages online platforms to use voluntary, proactive measures aimed at the detection and removal of illegal content and to step up cooperation and investment in, and use of, automatic detection technologies.”

This is similar to the much-discussed upload filters and raises the question whether such practice is in line with existing EU law. In the Sabam v Netlog case, the European Court of Justice previously ruled that hosting sites can’t be forced to filter copyrighted content, as this would violate the privacy of users and hinder freedom of information.

Importantly, the Commission emphasizes that when online services explicitly search for pirated material, they won’t lose the benefit of the liability exemption provided for in Article 14 of the E-Commerce Directive. In other words, copyright holders can’t hold these services accountable for content that slips through the net.

The recommendation further includes some specific suggestions to make sure that content, once removed, does not reappear. This is the notice-and-stay-down approach copyright holders are lobbying for, which can be addressed by content recognition tools including hash filtering.

“The Commission strongly encourages the further use and development of automatic technologies to prevent the re-appearance of illegal content online,” the document reads, adding that errors should not be overlooked.

“Where automatic tools are used to prevent re-appearance of illegal content a reversibility safeguard should be available for erroneous decisions, and the use and performance of this technology should be made transparent in the platforms’ terms of service.”

Hash-based and other automatic filters are not new of course. Services such as Google Drive and Dropbox already have these in place and YouTube’s Content-ID system also falls into this category.

Another measure to prevent re-uploading of content is to ban frequent offenders. The Commission notes that services should take appropriate measures against such users, which could include the suspension or termination of accounts.

Most of the suggestions come with a recommendation to have sufficient safeguards in place to repair or prevent errors. This includes a counter-notice process as well as regularly published transparency reports. In some cases where context is relevant, it is important to have a human reviewer in the loop.

Finally, the Commission encourages cooperation between online services and so-called “trusted flaggers.” The latter are known representatives of copyright holders who are trusted. As such, their takedown notices can be prioritized.

“Notices from trusted flaggers should be able to be fast-tracked by the platform. This cooperation should provide for mutual information exchange so as to evaluate and improve the removal process over time.”

The proposals go above and beyond current legal requirements. For many larger online services, it might not be too hard to comply with most of the above. But, for smaller services, it could be quite a burden.

European Digital Rights (EDRi) has highlighted some good and bad elements but remains critical.

“The document puts virtually all its focus on internet companies monitoring online communications, in order to remove content that they decide might be illegal. It presents few safeguards for free speech, and little concern for dealing with content that is actually criminal,” EDRi writes.

Google has also been critical of the notice-and-stay-down principle in the past. Copyright counsel Cédric Manara previously outlined several problems, concluding that the system “just won’t work.
