Quantum Dots Create Distance Between Electron Spins for Quantum Computing
Scientists at the Niels Bohr Institute have realized the swap of electron spins between distant quantum dots. This is significant for future quantum communications because it will allow the distance between the quantum dots to be large enough for integration with traditional microelectronics and, perhaps, a future quantum computer.

Nanoscale Patterning of Light Manipulates Macroscale Objects
By creating a distinct nanoscale patterning on the surface of an object, researchers at the California Institute of Technology have designed a way to levitate and propel objects using only light. The patterning interacts with light in such a way that the object can right itself when perturbed, creating a restoring torque to keep it in the light beam.

Finger-Mounted Optical Probe Designed to Improve Breast Cancer Removal
Researchers have developed a wearable probe that enhances the sense of touch by imaging and quantifying the stiffness and elasticity of biological tissue in order to improve the surgical removal of breast cancer. The finger-mounted probe uses a technique called quantitative micro-elastography (QME) to translate the sense of touch into high-resolution images.

In a New Quantum Simulator, Light Behaves Like a Magnet
Physicists at École Polytechnique Fédérale de Lausanne have proposed a new quantum simulator — a laser-based device that could be used to study a range of quantum systems. The simulator could help scientists better understand the properties of complex materials under extreme conditions.

Quantum Dots Demonstrate High Luminescence Efficiency
A new technique for precisely measuring quantum dot performance focuses on how efficiently QDs re-emit the light they absorb. The results suggest that, contrary to long-standing concerns, QDs are defect-tolerant and their emission is comparable to the best single-crystal emissions.
