First ever blueprint for quantum computers unveiled

February 2, 2017

London, Feb 2: Scientists have unveiled the first ever practical blueprint to construct a large scale quantum computer, the most powerful computer on Earth that could revolutionise industry, science, medicine and commerce.

The work by scientists, including those from University of Sussex in the UK and Google, features the actual industrial blueprint to construct such a large-scale machine, more powerful in solving certain problems than any computer ever constructed before.

Once built, the computer's capabilities mean it would have the potential to answer many questions in science; create new, lifesaving medicines and solve the most mind-boggling scientific problems, researchers said.

It could also unravel the yet unknown mysteries of the furthest reaches of deepest space and solve some problems that an ordinary computer would take billions of years to compute.

The work features a new invention permitting actual quantum bits to be transmitted between individual quantum computing modules in order to obtain a fully modular large-scale machine capable of reaching nearly arbitrary large computational processing powers.

Previously, scientists had proposed using fibre optic connections to connect individual computer modules.

The invention introduces connections created by electric fields that allow charged atoms (ions) to be transported from one module to another.

The approach allows 100,000 times faster connection speeds between individual quantum computing modules compared to current state-of-the-art fibre link technology.

"For many years, people said that it was completely impossible to construct an actual quantum computer. With our work we have not only shown that it can be done but now we are delivering a nuts and bolts construction plan to build an actual large-scale machine," said Professor Winfried Hensinger from University of Sussex, who is leading the research.

"It was most important to us to highlight the substantial technical challenges as well as to provide practical engineering solutions," said Bjoern Lekitsch, also from the University of Sussex.

As a next step, the team will construct a prototype quantum computer, based on this design.

"The availability of a universal quantum computer may have a fundamental impact on society as a whole," Hensinger said.

The computer's possibilities for solving, explaining or developing could be endless. However, its size will be anything but small.

The machine is expected to fill a large building, consisting of sophisticated vacuum apparatus featuring integrated quantum computing silicon microchips that hold individual charged atoms (ions) using electric fields.

The blueprint to develop such computers has been made public to ensure scientists throughout the world can collaborate and further develop this brilliant, ground-breaking technology as well as to encourage industrial exploitation.

Mumbai, Jun 27: The Bombay High Court observed that COVID-19 patients from poor and indigent sections cannot be expected to produce documentary proof to avail subsidised or free treatment while getting admitted to hospitals.

The court on Friday was hearing a plea filed by seven residents of a slum rehabilitation building in Bandra, who had been charged ₹ 12.5 lakh by K J Somaiya Hospital for COVID-19 treatment between April 11 and April 28.

The bench of Justices Ramesh Dhanuka and Madhav Jamdar directed the hospital to deposit ₹10 lakh in the court.

The petitioners had borrowed money and managed to pay ₹10 lakh out of ₹12.5 lakh that the hospital had demanded, after threatening to halt their discharge if they failed to clear the bill, counsel Vivek Shukla informed the court.

According to the plea, the petitioners were also overcharged for PPE kits and unused services.

On June 13, the court had directed the state charity commissioner to probe if the hospital had reserved 20% beds for poor and indigent patients and provided free or subsidised treatment to them.

Last week, the joint charity commissioner had informed the court that although the hospital had reserved such beds, it had treated only three poor or indigent persons since the lockdown.

It was unfathomable that the hospital that claimed to have reserved 90 beds for poor and indigent patients had treated only three such persons during the pandemic, advocate Shukla said.

He further argued that COVID-19 patients, who are in distress, cannot be expected to produce income certificate and such documents as proof.

However, senior advocate Janak Dwarkadas, who represented the hospital, said the petitioners did not belong to economically weak or indigent categories and had not produced documents to prove the same.

A person who is suffering from a disease like COVID-19 cannot be expected to produce certificates from a tehsildar or social welfare officer before seeking admission in the hospital, the bench noted and asked the hospital to deposit ₹10 lakh in court within two weeks.

Consumer watchdog Which? has claimed that more than one billion Android phones and tablets are vulnerable to hackers as they no longer supported by security updates.

According to the research report, the most at-risk phones are any that run Android 4 or older and those smartphones running Android 7.0 which can not be updated are also at risk.

Based on data from Google analysed by Which?, two in five android device users around the world are no longer receiving the important updates. Currently, those devices are unlikely to have issues, but the lack of security leaves them open to attack.

"It is very concerning that expensive Android devices have such a short shelf life before they lose security support, leaving millions of users at risk of serious consequences if they fall victim to hackers," Kate Bevan editor Which? said in a statement.

"Google and phone manufacturers need to be upfront about security updates with clear information about how long they will last and what customers should do when they run out. The government must also push ahead with planned legislation to ensure manufacturers are far more transparent about security updates for smart devices and their impact on consumers," Kate added.

Android phone released around 2012 or earlier, including popular models like the Samsung Galaxy S3 and Sony Xperia S, are particularly at risk to hackers.

Which? has made suggestions to Android users on what to consider if they have an older phone that may be at risk.

Any Android device which is more than two years old, check whether it can be updated to a newer version of the operating system. If it is on an earlier version than Android 7.0 Nougat, try to update via Settings> System>Advanced System update.

In case a user is not able tto update the phone, the device could be at risk of being hacked if it is running a version of Android 4 or lower.

A user also need to be careful about downloading apps outside the Google Play store and should also install a mobile anti-virus via an app.

Twitter has hinted that it is planning a paid subscription platform that can be reused by other teams in the future.

The news that the micro-blogging platform is building a subscription platform with a team codenamed "Gryphon" resulted in Twitter stock rising over 8% on Wednesday.

Twitter revealed its plan via a job listing that seeks a full-stack senior software engineer in New York to join "Gryphon".

Interestingly, Twitter "edited" the job listing once the news broke, removing the part about "Gryphon" and any mention of their internal team or their subscription feature. The listing said the company is looking for an Android engineer to "work on a bevy of backend engineering teams to build components that allow for experimentation to deliver the best experience possible to all of our users".

Later, Twitter users noticed that the company restored the earlier job listing that mentioned the upcoming subscription platform and "Gryphon".

A spokesperson for Twitter told CNN on Wednesday that it's only a job posting, not a product announcement.

This is not the first time Twitter has thought of a paid product. 

In 2017, it sent out a survey to users and a preview of what a premium offering of its TweetDeck app might look like, including breaking news alerts and more analytics, according to The Verge.

"We're conducting this survey to assess the interest in a new, more enhanced version of Tweetdeck. We regularly conduct user research to gather feedback about people's Twitter experience and to better inform our product investment decisions, and we're exploring several ways to make TweetDeck even more valuable for professionals," a Twitter spokesperson had said at that time.
