Watching Qubits At Work

As previously discussed, part of the appeal of qubits based on nitrogen-vacancy (N-V) defect centers in diamond is the ability to manipulate them with light. Light pulses can be used both to initialize the qubit array and to measure the results of quantum computations. As recent work at The University of Chicago shows, light can also be used to study the evolution of the quantum state in the... » read more

Manufacturing Bits: Oct. 8

X-Ray Vision Researchers led by the University of Manchester have developed a new type of X-ray vision. The technology can look inside objects and map the properties in 3D and in real time. This technology is called pair distribution function-computed tomography. Applications include materials science, biomaterials, geology, environmental science and palaeontology. The technology enable... » read more
