Vint Cerf On Alan Turing

Photo: Joseph Birr-Pixton (CC)Vint Cerf was one of the main forces behind the creation of the Internet as we know it today. He is accorded elder statesman status, but is in fact still very active in the tech world (currently Google’s “Chief Internet Evangelist”). On the centenary of the birth of an earlier tech revolutionary, Alan Turing, Cerf writes for the BBC that  the mathematician who broke the Nazis’ Enigma code in World War 2 should be a household name:

I’ve worked in computing, and more specifically computer networking, nearly all my life. It’s an industry in a constant state of innovation, always pushing beyond the limits of current capability.

It is sometimes said that “broadband” is whatever network speed you don’t have, yet!

Things we take for granted today were, not that long ago, huge technological breakthroughs.

Although I’ve been lucky enough in my career to be involved in the development of the internet, I’ve never lost sight of the role played by my predecessors, without whose pioneering labour, so much would not have been accomplished.

Alan Turing Code Papers Released

Turing PlaqueAlan Turing, perhaps the greatest computer scientist ever, famous for breaking the Germans’ Enigma code in World War II, wrote two papers on code breaking that have just been released by Britain’s spy center, GCHQ. From BBC News:

Two 70-year-old papers by Alan Turing on the theory of code breaking have been released by the government’s communications headquarters, GCHQ.

It is believed Turing wrote the papers while at Bletchley Park working on breaking German Enigma codes. A GCHQ mathematician said the fact that the contents had been restricted “shows what a tremendous importance it has in the foundations of our subject”.

It comes amid celebrations to mark the centenary of Turing’s birth. The two papers are now available to view at the National Archives at Kew, west London. GCHQ was able to approximately date the papers because in one example Turing had made reference to Hitler’s age.

Why The Age Of Quantum Computing Is Nearer Than You Think

DPAG1998-Max-Planck-GesellschaftTrevor Quirk reports in the Christian Science Monitor that new research at the Max Planck Institute of Quantum Optics shows quantum computing beginning to flirt with practical technology:

Tech-buffs, investors, IT industrialists, and boffins alike eagerly await the day when the science of quantum computing yields practical technology. Physicists of the Max Planck Institute of Quantum Optics (MPQ), recently published research that, they believe, has brought that pivotal day closer.

For many years, physicists have sought to create an information network far superior to today’s by exploiting quantum phenomena. The team of German researchers have constructed the first vital component of such a network: a link between two atomic nodes over which information can be received, sent, and stored using a single photon. Successful exchanges of information recently took place in Garching, Germany, between two MPQ labs connected by a 60-meter fiber-optic cable. Though only a prototype, this rudimentary network could be scaled up to more complex and distanced quantum networks.
