Latest Superconducting quantum computing Stories
Researchers at the National Institute of Standards and Technology (NIST) have created a tunable superconducting circuit on a chip that can place a single microwave photon (particle of light) in two frequencies, or colors, at the same time. This curious "superposition," a hallmark of the quantum world, is a chip-scale, microwave version of a common optics experiment in which a device called a beam-splitter sends a photon into either of two possible paths across a table of lasers, lenses and...
Scientists at the National Institute of Standards and Technology (NIST) have developed the first "dimmer switch" for a superconducting circuit linking a quantum bit (qubit) and a quantum bus"”promising technologies for storing and transporting information in future quantum computers. The NIST switch is a new type of control device that can "tune" interactions between these components and potentially could speed up the development of a practical quantum computer. Quantum computers, if...
Physicists at UC Santa Barbara have made an important advance in quantum mechanics using a superconducting electrical circuit. The finding is reported in this week's issue of the journal Nature. The researchers showed that they could detect the quantum correlations in the results of measurements of entangled quantum bits, using a superconducting electrical circuit. The correlations are stronger than can be obtained using classical (non-quantum mechanical) physics, and according to the...
