It's not quite a quantum internet — yet. But researchers at Los Alamos National Laboratory in New Mexico have developed a new, ultra-secure computer network that is capable of transmitting data that has been encrypted by quantum physics, including video files. The network, which currently consists of a main server and three client machines, has been running continuously in Los Alamos for the past two and a half years, the researchers reported in a paper released earlier this month. During that time, they have also successfully tested sending critical information used by power companies on the status of the electrical grid. Eventually they hope to use it to test offline quantum communication capabilities on smartphones and tablets.

Multi-Party Computation: From Theory to Practice

Google Tech Talk 1/8/13 Presented by Nigel P. Smart ABSTRACT Multi-Party Computation (MPC) allows, in theory, a set of parties to compute any function on their secret input without revealing anything bar the output of the function. For many years this has been a restricted to a theoretical tool in cryptography. However, in the past five years amazing strides have been made in turning theory into practice. In this talk I will present the latest, practical, protocol called SPDZ (Speedz), which achieves much of its performance advantage from the use of Fully Homomorphic Encryption as a sub-procedure. No prior knowledge of MPC will be assumed. Speaker Info University of Bristol, UK

AudioGL presents a new vision of visual music creation, extended into space. Images courtesy the developer.

Here in flatland, ideas for musical interfaces may have become largely well-trodden. Not so in the third dimension. And so, one of the most unusual audiovisual interfaces has now hit beta, ready for you to explore. And that does mean “explore”: think navigation through spinning, animated galaxies of musical objects in this spatial modular sound environment. With the beta available, you can determine whether that´s a bold, new final frontier, or just the wheel, reinvented.

The work of Toronto-based artist and engineer Jonathan Heppner, AudioGL is a stunning vision of music creation in 3D space, with modular synths, advanced user-editable modulation, and a freely-navigable, open-ended spatial workspace.

There is a ticket for entry. While marked “beta,” the developer has admitted he needs money. And so, a trip into the space elevator will cost you US$80 for a fully-enabled license. You can try a save-disabled version for free, however, which isn’t necessarily a deal-killer for software of this nature; I’d mark this one down practically to crowd-funding for those who like the concept. (For an open-source take on graphical, spatial music sequencing, check out Iannix – and it does seem this sort of experimentalism could benefit from open licenses.) One caveat on the beta licenses: they won’t apply to the finished version. (Seems working something out there and talking about it publicly would encourage more beta users.)

This is the first beta; upcoming betas are due every 2-3 months, says the author. There’s already a lot there:

  • Immersive 3D interface
  • Preset instruments
  • Moular synth
  • Sample-accurate automation
  • Envelopes
  • Project-wide modulation
  • MIDI support
  • Sample import
  • Audio export

AudioGL isn’t limited to compelling 3D ideas. Project–wide modulation means networks of transformations that work across a scene.

For fine-grained editing of user envelopes, AudioGL does offer a more conventional 2D view.

At the top of the to-do list: ReWire, VST instruments and effects, and enhanced tempo change and modulation. Further down the line, says the developer, are DAW-style features like arrangement and project management.

No new videos of this build, but an impressive previous video is available below.
