What is the latest development in Quantum Computing ?
Using electromagnetic waveguides on diamond-based chips, the researchers were able to generate magnetic fields large enough to change the quantum state of an atomic-scale defect in less than one billionth of a second. The microwave techniques used in the experiment are analogous to those that underlie magnetic resonance imaging (MRI) technology.
The key achievement in the current work is that it gives a new perspective on how such resonant manipulation can be performed. "We set out to see if there is a practical limit to how fast we can manipulate these quantum states in diamond," said lead author Greg Fuchs, a postdoctoral researcher at UCSB. "Eventually, we reached the point wh ...more
Although quantum computing is still in its infancy, experiments have been carried out in which quantum computational operations were executed on a very small number of qubits (quantum bit). Both practical and theoretical research continues with interest, and many national government and military funding agencies support quantum computing research to develop quantum computers for both civilian and national security purposes, such as cryptanalysis
