Cracking the quantum code: Simulations track entangled quarks

Today, the word "quantum" is everywhere—in company names, movie titles, even theaters. But at its core, the concept of a quantum—the tiniest, discrete amount of something—was first developed to explain the behavior ...

Scientists compute with light inside hair-thin optical fiber

Scientists at Heriot-Watt University in Edinburgh, Scotland, have found a powerful new way to program optical circuits that are critical to the delivery of future technologies such as unhackable communications networks and ...

Two qudits fully entangled

In the world of computing, we typically think of information as being stored as ones and zeros—also known as binary encoding. However, in our daily life we use ten digits to represent all possible numbers. In binary the ...

Physicists reach qubit computing breakthrough

Researchers from Arizona State University and Zhejiang University in China, along with two theorists from the United Kingdom, have been able to demonstrate for the first time that large numbers of quantum bits, or qubits, ...
