Better info transfer marks step forward for quantum computing By Lance VaughnMay 07, 2021 Quantum science has the potential to revolutionize modern technology with more efficient computers, communication, and sensing devices. But challenges remain in achieving these technological goals, especially when it comes to effectively transferring information in quantum systems. A regular computer consists of billions of transistors, called bits. Quantum computers, on the other hand, are based on quantum bits, also known as qubits, which can be made from a single electron. Unlike ordinary transistors, which can be either “0” (off) or “1” (on), qubits can be both “0” and “1” at the same time. The ability of individual qubits to occupy these so-called superposition states, where they...

Optical Fiber Brings Universal Quantum Computing Closer | Research & Technology | Mar 2021

GAITHERSBURG, Md., March 25, 2021 — Physicists at the National Institute of Standards and Technology (NIST) measured and controlled a superconducting qubit using optical fiber rather than metal electrical wires. The work paves the way to being able to pack a million qubits into a quantum computer rather than just a few thousand and introduces the possibility of a universal quantum computer capable of solving the most difficult equations. Superconducting circuits are a leading technology for making quantum computers because they are reliable and easily mass produced. But these circuits must operate at cryogenic temperatures, and schemes for wiring them to room-temperature electronics are complex and prone to overheating the qubits. Conventional cryostats — supercold dilution refrigerators — with metal wiring can support only thousands of...

Now that’s edge computing — GCN

Now that’s edge computing Astronauts at the International Space Station will soon be taking delivery of an HPE Spaceborne Computer-2 (SBC-2). Expected to be in service for two to three years, the edge computing device will connect ISS users to Microsoft’s Azure cloud. In 2107, NASA sent the first Spaceborne Computer, an HPE Linux machine, to the ISS to give astronauts high-performance computing capabilities for onboard operations and provide extra power for their experiments.   The ruggedized SBC-2 is built on the HPE Edgeline Converged Edge system and offers twice the compute speed as the original Spaceborne Computer. GPUs allow SBC-2 to more easily ingest and process image-intensive data from satellites, environmental sensors and cameras in real time. The GPU capabilities will also support specific...
