Stanford has a new measurement technique for quantum dots. Uncertainty about the quality of quantum dots are holding back the use of quantum dots. Above – A close-up artist’s rendering of quantum dots emitting light they’ve absorbed. (Image credit: Ella …

physicsTwo Different Quantum Dot Qubits Combined to Overcome Limitations

RIKEN Center for Emergent Matter Science has constructed a hybrid quantum device made from two different types of qubits. They have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. They …

nanowireSuperconducting nanowires created that are promising for future quantum computers

Dutch researchers have successfully developed nanowires allowing individual electrons to be captured by a ‘quantum dot’ on which superconductivity can take place. These nanowires could make powerful quantum computers. The combination of a quantum dot and superconductivity makes it possible …

energyLos Alamos quantum dots will make cost effective double-pane solar windows

Using two types of “designer” quantum dots, researchers are creating double-pane solar windows that generate electricity with greater efficiency and create shading and insulation for good measure. It’s all made possible by a new window architecture which utilizes two different …
