Scientists capture first ever image of light acting as a particle and a wave

Ryan Whitwam via ExtremeTech:

Despite being a well-established tenet of modern physics, the particle-wave duality of light can be a real mind-bender. This approach to understanding the universe was pioneered by scientists like Albert Einstein and Max Planck, eventually leading to quantum mechanics. Researchers have been trying to visualize light in both forms ever since, but haven’t had success until now. A team at the Swiss Federal Institute of Technology in Lausanne (EPFL) claim they’ve devised an experiment to photograph light as both a particle and wave.

Einstein’s eureka moment in the study of light came when he described the photoelectric effect. When UV light hits a metal surface, it results in an emission of electrons. Einstein explained this phenomenon by proposing that light can act as a particle in addition to a wave. We now know these particles as photons, but that term wasn’t coined until later. Subsequent experiments have confirmed the dual property of light, but actually seeing both at once would be something.

NSA Trying To Build Quantum Computer That Could Break All Forms Of Encryption

quantum computingTrying to maintain your privacy? Consider just giving up. The Washington Post reports:

In room-size metal boxes ­secure against electromagnetic leaks, the National Security Agency is racing to build a computer that could break nearly every kind of encryption used to protect banking, medical, business and government records around the world.

According to documents provided by former NSA contractor Edward Snowden, the effort to build “a cryptologically useful quantum computer” — a machine exponentially faster than classical computers — is part of a $79.7 million research program titled “Penetrating Hard Targets.” Much of the work is hosted under classified contracts at a laboratory in College Park, Md.

The development of a quantum computer has long been a goal of many in the scientific community. With such technology, all current forms of public key encryption would be broken, including those used on many secure Web sites as well as the type used to protect state secrets.

Skynet rising: Google acquires 512-Qubit Quantum Computer; NSA Surveillance to be Turned Over to AI Machines

Most people don’t know about the existence of quantum computers. Almost no one understands how they work, but theories include bizarre-sounding explanations like, “they reach into alternate universes to derive the correct answers to highly complex computational problems.”

Quantum computers are not made of simple transistors and logic gates like the CPU on your PC. They don’t even function in ways that seem rational to a typical computing engineer. Almost magically, quantum computers take logarithmic problems and transform them into “flat” computations whose answers seem to appear from an alternate dimension.

For example, a mathematical problem that might have 2 to the power of n possible solutions — where n is a large number like 1024 — might take a traditional computer longer than the age of the universe to solve. A quantum computer, on the other hand, might solve the same problem in mere minutes because it quite literally operates across multiple dimensions simultaneously.
