The concept of "symmetry" is essential to fundamental physics: a crucial element in everything from subatomic particles to macroscopic crystals. Accordingly, a lack of symmetry—or asymmetry—can drastically affect the properties of a given system....

Full control of a six-qubit quantum processor in silicon

 Quantum Physics News
 28 September 2022
Researchers at QuTech—a collaboration between the Delft University of Technology and TNO—have engineered a record number of six, silicon-based, spin qubits in a fully interoperable array. Importantly, the qubits can be operated with a low error-rate that is achieved with a new chip design, an...

Spiral dislocation gives 3D topological photonics a robust edge

 Physics General News
 28 September 2022
Crystals have enthralled humans for thousands of years with their visual beauty and elegant symmetrical shapes, and, more recently, with their numerous technological applications. Fundamentally, these materials are based on a highly regular arrangement of their smallest constituent elements, and the...

The process of waves carrying plasma heat is observed for the first time

 Physics General News
 28 September 2022
In fusion power generation, it is essential that the high-energy particles generated by a fusion reaction in hot plasma heat it to sustain further fusion reactions. The key to this self-heating of the plasma is whether it can be heated by waves created by the high-energy particles....

Researchers observe excitonic Bloch-Siegert shift in quantum dots

 Quantum Physics News
 28 September 2022
A research group led by Prof. Wu Kaifeng and Zhu Jingyi from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences recently reported the observation of an excitonic Bloch-Siegert shift in CsPbI3 perovskite quantum dots (QDs), which advances current fundamental understanding for...
