Sacred electronics

Drawing on Hindu and Buddhist symbolism, London-based artist Leonardo Ulian explores technology and spiritualism through these sculpted mandalas created with soldered computer and radio components, in a collection he calls Sacred Space.

We live in a society that worships electronic technology,” he states “both for necessity but also because it makes us feel better, not unlike its own new form of fashionable spirituality.”

Quantum teleportation breakthrough

In a huge step towards making quantum computing a reality, researchers have successfully teleported complete quantum bits of information for the first time. Previous attempts dating back to 1997 resulted in losses of information, and was considered to be too inefficient for any practical use. A new hybrid technique is over 100 times more efficient. It combines technology for transporting light waves with a broad frequency range, and technology for reducing the frequency range of photonic quantum bits. The result is that the bits are incorporated as lightwaves without disruption by noise, and don’t require measurement after transport — constituting “a major advance toward quantum information processing technology”.

The group of researchers at the University of Tokyo explained the breakthrough:

“I think we can definitely say that quantum computers have come closer to reality. Teleportation can be thought of as a quantum gate where input and output are the same. So, it’s known that, if we improve this a little, the input and output could be produced in different forms. If changing the form of input and output like that is considered as a program, you have a programmable quantum gate. So, I think a quantum computer could be achieved by combining lots of those.”
