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.
“Compressive sensing” provides new approach to measuring a quantum system
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.
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?
Quantum Optics Leaders Convene in Rochester
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.
Exploiting Subtleties in the Uncertainty Principle
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.
Dark Matter Detector Installed Underwater, Underground
An experiment to look for one of nature’s most elusive subatomic particles is underway in a stainless steel tank nearly a mile underground beneath the Black Hills of South Dakota. And among the dozens of scientists involved in the research is physics Professor Frank Wolfs.
University of Rochester Plays Key Roles in Search for Higgs Boson
July 4, 2012, was an historic day for researchers at CERN. It also marked an important period at the University of Rochester as three physicists and an engineer helped support the nearly five-decades-old theory of one of their colleagues.
