Quantum magic makes quick work of measuring frequency

Using the strange rules of quantum mechanics, researchers were able to put a quantum bit in a superposition of two different energy states at the same time in order to speed up the accurate measurement of frequencies.

Enigma Machine takes a quantum leap

Researchers have developed a “quantum enigma machine” to improve on data encryption. The device manipulates photons to create an unbreakable encrypted message with a key that’s far shorter than the message—the first time that has ever been done.

Drawing a line between quantum and classical: Bell’s Inequality fails test as boundary

The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.

Researchers send electricity, light along same super-thin wire

A new combination of materials can efficiently guide electricity and light along the same tiny wire, a finding that could be a step towards building computer chips capable of transporting digital information at the speed of light.

Doing more with less: New technique efficiently finds quantum wave functions

University researchers have introduced a new method, called compressive direct measurement, that allowed the team to reconstruct a quantum state at 90 percent fidelity using only a quarter of the measurements required by previous methods.

Duality principle is “safe and sound”: Researchers clear up apparent violation of quantum mechanics’ wave-particle duality

When scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, The results were both “strange” and “incredible.” It took Robert Boyd and his colleagues nearly a year and a half to figure out what was going on.

Mapping the optimal route between two quantum states

As a quantum state collapses, it will follow a path known as a quantum trajectory. In a new paper featured this week on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a theory, recently developed by University of Rochester physicists, for predicting the most likely path a system will take.

New Type of Neutrino Oscillation Confirmed

The new finding could help explore a fundamental question of science – why is the universe made up almost exclusively of matter, when matter and antimatter were created in equal amounts in the Big Bang?
