Physicists Build the First Quantum Interface
By linking a single ion with a single proton, physicists at the University of Innsbruck have established the first quantum interface between quantum processors and optical information channels.
What's the Latest Development?
Physicists at the University of Innsbruck have taken an essential step toward creating quantum computers, which may prove vastly more powerful than today's chip-based technology. By creating a network that interfaces between a single ion and a single proton, in a way that is both "efficient and freely tunable," the physicists have created the first link between quantum processors and optical information channels. "At the core of the experiment lies an optical resonator consisting of two highly reflective mirrors. Photons bounce back and forth up to 25,000 times between these mirrors, interacting with the ion, before escaping through one mirror into an optical fiber."
What's the Big Idea?
Unlike classical information, quantum data cannot be copied without being corrupted, thus physicists must find a way to transfer the data between matter and light using entanglement, "the quantum property in which the state of one particle depends on the state of a second." Tracy Northup of the University of Innsbruck's Institute for Experimental Physics said: "Whenever we have to transfer quantum information from processing sites to communication channels, and vice versa, we’re going to need an interface between light and matter." Having a better understanding of this essential interface may help to develop quantum computers as well as a quantum Internet.

A completely unexpected discovery beneath the ice.
- Scientists find remains of a tardigrade and crustaceans in a deep, frozen Antarctic lake.
- The creatures' origin is unknown, and further study is ongoing.
- Biology speaks up about Antarctica's history.
Bushier eyebrows are associated with higher levels of narcissism, according to new research.
- Science has provided an excellent clue for identifying the narcissists among us.

It's one factor that can help explain the religiosity gap.
- Sociologists have long observed a gap between the religiosity of men and women.
- A recent study used data from several national surveys to compare religiosity, risk-taking preferences and demographic information among more than 20,000 American adolescents.
- The results suggest that risk-taking preferences might partly explain the gender differences in religiosity.
