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...

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...

Quantum technology reaches unprecedented control over captured light

 Quantum Physics News
 27 September 2022
Researchers in quantum technology at Chalmers University of Technology have succeeded in developing a technique to control quantum states of light in a three-dimensional cavity. In addition to creating previously known states, the researchers are the first ever to demonstrate the long-sought cubic...

Physicists shed light on a different kind of chaos

 Quantum Physics News
 26 September 2022
Physicists at UC Santa Barbara, the University of Maryland, and the University of Washington have found an answer to the longstanding physics question: How do interparticle interactions affect dynamical localization?...

Exotic electronic effect found in 2D topological material

 Quantum Physics News
 26 September 2022
Jülich researchers have been able to demonstrate an exotic electronic state, so-called Fermi Arcs, for the first time in a 2D material. The surprising appearance of Fermi arcs in such a material provides a link between novel quantum materials and their respective potential applications in a new...

'Twisty' photons could turbocharge next-gen quantum communication

 Quantum Physics News
 22 September 2022
Quantum computers and communication devices work by encoding information into individual or entangled photons, enabling data to be quantum securely transmitted and manipulated exponentially faster than is possible with conventional electronics. Now, quantum researchers at Stevens Institute of...
