Shielded quantum bits

A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. The researchers have found ways to shield electric and ...

Researchers successfully demonstrate a quantum gate in silicon

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland have developed a stable quantum gate for two-quantum bit systems made of silicon. ...

Are animal migrations social?

Migratory animals include a wide range of species—from tiny insects to the world's largest marine mammals. To achieve their journeys, migrants must walk, swim, or fly, often traversing complex landscapes that requires many ...

Lungfish fins reveal how limbs evolved

The evolution of limbs with functional digits from fish fins happened approximately 400 million years ago in the Devonian. This morphological transition allowed vertebrates to leave the water to conquer land and gave rise ...

Laser light used to modulate free electrons into qubits

The laws of quantum physics are not only extraordinary—they also offer some far-reaching and unique possibilities for advanced information processing, quantum computing and cryptography. So far, the basic building blocks ...

Researchers demonstrate attosecond boost for electron microscopy

A team of physicists from the University of Konstanz and Ludwig-Maximilians-Universität München in Germany have achieved attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave ...

The puzzle of the 'lost' angular momentum

In a closed physical system, the sum of all angular momentum remains constant, according to an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily rotation in this context: ...
