Researchers create powerful quantum source with meta-lens array

Researchers for the first time have demonstrated a quantum light source based on a meta-lens array. The approach offers a promising platform for both high-dimensional photon entanglement and the coherent control of multiple ...

New cold atom source lays groundwork for portable quantum devices

Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum ...

Insulators turn up the heat on quantum bits

Physicists have long suspected that dielectric materials may significantly disrupt ion-trap quantum computers. Now, researchers led by Tracy Northup have developed a new method to quantify this source of error for the first ...

Future sparkles for diamond-based quantum technology

Marilyn Monroe famously sang that diamonds are a girl's best friend, but they are also very popular with quantum scientists—with two new research breakthroughs poised to accelerate the development of synthetic diamond-based ...

New boost in quantum technologies

In an international collaboration, researchers at the University of Stuttgart were able to detect quantum bits in two-dimensional materials for the first time. Nature Materials publishes this research in its May 6, 2021 issue.
