An undergraduate computer science student has created a “quantum chess” game that stumps computers’ ability to search all possible outcomes of possible moves by having chess pieces mimic particles that are subject to quantum mechanics.

The chess pieces follow the principle of superposition: they can exist(…)

The uncertainty principle is at the foundation of quantum mechanics: You can measure a particle’s position or its velocity, but not both. Now it seems that quantum computer memory could let us violate this rule.

The theoretical underpinnings of the uncertainty principle(…)

I don’t know when optical quantum computers are going to arrive, but I sure hope they look like this crazy Toshiba visualization of an Entangled Light Emitting Diode. This new LED type could finally make practical quantum computers possible.

According to Mark Stevenson—from(…)

Take a few of my favorite subjects: quantum dots, satellites, and gold. Mix them together, and what do you get? A breakthrough from Rensselaer Polytechnic Institute that could revolutionize infrared detection. Somewhere, the Predator is jealous.

What the RPI researchers have managed to(…)

It only measures seven atoms but, according to project lead scientist Michelle Simmons, computers made with this transistor—the smallest ever made—will “solve problems that would take longer than the life of the universe with a classical computer.”

Simmons says that the silicone(…)
