The best guide to the boundary between our everyday world and the 鈥渟pooky鈥� features of the quantum world has been a theorem called Bell鈥檚 Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.

Anton Zeilinger, one of the world鈥檚 leading experts in the field of quantum optics, will present a free, public lecture Tuesday at the University of Rochester. The talk is designed to convey the exciting frontiers of quantum mechanics to a general audience.

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.

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.

When scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, The results were both 鈥渟trange鈥� and 鈥渋ncredible." It took Robert Boyd and his colleagues nearly a year and a half to figure out what was going on.

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 暗网吃瓜 physicists, for predicting the most likely path a system will take.

Physicists have shown that a technique called compressive sensing offers a way to measure both variables at the same time, without violating the Uncertainty Principle.

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

Two hundred physics and optics researchers from 20 countries worldwide have come together at the University of Rochester this week for the Tenth Rochester Conference on Coherence and Quantum Optics.

Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light.
