What could the NSA do with a quantum computer?

After many false starts it’s a research field that is just now coming of age - when harnessed, particles can perform staggeringly powerful computation.

The news that the US National Security Agency has been spying on public emails, phone calls and internet chat logs provokes an obvious question: just how much data can the NSA cope with? That depends on whether it has a working quantum computer.

A report leaked to the Guardian suggests that the NSA can get three billion pieces of information a month from computer records alone. Much has been made of how it would take ridiculous amounts of computer time to analyse it all. But that is exactly why the NSA, GCHQ and almost every other security agency in the world have spent the past two decades with one eye on a select group of physicists who could soon make the supercomputers of today look like children’s toys.

A standard “classical” computer stores information as a series of zeroes and ones on the microchips of its circuitry. A 0 is represented by the absence of electrical charge on a component called a capacitor. The presence of charges gives a 1. By moving the charges around between components in welldefined ways, you can represent any number you want and perform any computation.

The quantum computer uses a single atom or electron, rather than a bulky electrical charge, as the 0 or 1. In fact, the particle can be 0 and 1 at the same time. In certain conditions, atoms and subatomic particles can be in two places at once, or spin clockwise and anticlockwise at the same time. That means you can use a single atom to represent two binary digits.

Then there’s entanglement, another phenomenon of the subatomic world. This allows you to link many of the doubleheaded particles to create a string of binary digits that can simultaneously represent a huge array of numbers. A string of just 250 particles is enough to encode, simultaneously, more numbers than there are atoms in the known universe. Put those particles together in the form of a computer, and they can perform a staggeringly powerful computation on all these possible numbers at once.

So far, researchers have identified two applications for quantum computing. The first is a kind of reverse multiplication known as factorisation. This allows you to discover which numbers multiply each other to create any given number. It sounds trivial, but if the bigger number is big enough, no normal computer can do this in a reasonable time. The difficulty of factorisation is the mainstay of all data security, from military intelligence to financial transactions. So, a quantum computer is a game-changer.

The second application seems even more esoteric at first glance. It is a reverse telephonebook search: given a number, it can do the equivalent of finding a name, and much more quickly than any machine we have now. It is a way of sifting through unsorted data efficiently – just what the NSA needs.

And after many false starts it’s a research field that is just now coming of age. The first working, commercial quantum computer was created by DWave Systems, a firm based in Vancouver, Canada. Its first sale, in May 2011, was to the defence company Lockheed Martin, which has links with the NSA.

A major investor in D-Wave is In-Q-Tel, the business arm of the CIA, which “delivers innovative technology solutions in support of the missions of the US intelligence community”. IQT believes its customers can benefit from the promise of quantum computing because the intelligence world faces “many complex problems that tax classical computing”, according to Robert Ames, an IQT vice-president. He made that statement in September last year. Now we know just what he meant.

The second coming of Gordon Ramsay

A star is reborn. 

It would be a lie to say that Gordon Ramsay ever disappeared. The celebrity chef made his television debut in 1997 and went on to star in shows in 1998, 2001, 2004, 2005, 2006, 2007, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, and 2017. There hasn’t been a lull in Ramsay’s career, which has arguably gone from strength to strength. In 2000, he was cooking for Vladimir Putin and Tony Blair – in 2008, he ate the raw heart of a dead puffin.

Left: Gordon Ramsay shaking hands with Vladimir Putin. Right: Gordon Ramsay hugging a puffin (different from the one he ate).

Yet we are, undeniably, in the middle of a Ramsay renaissance. How? How could a man that conquered the last twenty years of cookery-based television have an upsurge in popularity? There are only so many television channels – so many amateur donkey chefs. Wrong. The internet has enabled a Ramsay resurgence, the second act of a play overflowing with blood, sweat, and French onion soup.

Wow.

We all, of course, know about Gordon’s Twitter account. Although started in 2010, the social media profile hit the headlines in February this year when Ramsay began rating food cooked by the world’s amateur-amateur chefs. But other elements of Ramsay’s internet celebrity are more miraculous and mysterious.

His official YouTube channel uploads, on average, three videos a week. Decades old clips from Kitchen Nightmares accumulate over three million views in as many days. A 15,000 follower-strong Facebook fan page for the show – which premiered in 2007 and ended in 2014 – was set up on 19 June 2017.

Wow, wow, wow, wow. Wow.

What makes a meme dank? Academics don’t know. What is apparent is that a meme parodying Gordon Ramsay’s fury over missing lamb sauce (first aired on Hell’s Kitchen in 2006) had a dramatic upsurge in popularity in December 2016. This is far from Gordon’s only meme. Image macros featuring the star are captioned with fictitious tirades from the chef, for example: “This fish is so raw… it’s still trying to find Nemo”. A parody clip from The Late Late Show with James Cordon in which Ramsay calls a woman an “idiot sandwich” has been watched nearly five million times on YouTube.

And it is on YouTube where Ramsay memes most thrive. The commenters happily parrot the chef’s most memable moments, from “IT’S RAW” to the more forlorn “fuck me” after the news something is frozen. “HELLO MY NAME IS NINOOOOO!” is an astonishingly popular comment, copied from a clip in which a Kitchen Nightmares participant mocks his brother. If you have not seen it – you should.

But what does all this mean for Ramsay’s career? His YouTube channel and Facebook page are clearly meticulously managed by his team – who respond to popular memes by clipping and cutting new videos of classic Ramsay shows. Although this undoubtedly earns a fortune in ad revenue, Ramsay’s brand has capitalised on his internet fame in more concrete ways. The chef recently voiced Gordon Ramsay Dash, a mobile game by Glu Games Inc in which you can cook with the star and he will berate or praise you for your efforts. Ten bars of gold – which are required to get upgrades and advance in the game – cost 99p.

Can other celebrity chefs learn from Ramsay? A generation will never forgive that twisted, golden piece of meat, Jamie Oliver, for robbing them of their lunch time Turkey Twizzlers. But beyond this, the internet’s love is impossible to game. Any celebrity who tried to generate an online following similar to Ramsay’s would instantly fail. Ramsay’s second coming is so prolific and powerful because it is completely organic. In many ways, the chef is not resposible for it. 

In truth, the Ramsay renaissance only worked because it was - though the chef himself would not want to admit it - completely raw.
