Chemists go ‘back to the future’ to untangle quantum dot mystery

For more than 30 years, researchers have been creating quantum dots—nanoscale semiconductors with remarkable properties. But quantum dot synthesis has occurred largely by trial and error. Thanks to the work of two Rochester chemists, that may be about to change.

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.
