Quantum marbles in a bowl of light

Which factors determine how fast a quantum computer can perform its calculations? Physicists at the University of Bonn and the Technion—Israel Institute of Technology have devised an elegant experiment to answer this question. ...

Research: Wreck of last US slave ship mostly intact on coast

Researchers studying the wreckage of the last U.S. slave ship, buried in mud on the Alabama coast since it was scuttled in 1860, have made the surprising discovery that most of the wooden schooner remains intact, including ...

New materials for quantum technologies

While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max ...

Scientists demonstrate a novel rocket for deep-space exploration

The growing interest in deep-space exploration has sparked the need for powerful long-lived rocket systems to drive spacecraft through the cosmos. Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics ...

New dates for the start of Viking-age trade

Mobility shaped the human world profoundly long before the modern age. But archaeologists often struggle to create a timeline for the speed and impact of this mobility. An interdisciplinary team of researchers at the Danish ...

Integrated photonics meets electron microscopy

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics—circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes ...
