World Record in Data Transmission With Smart Circuits

World Record in Data Transmission With Smart Circuits

Fewer cords, smaller antennas and quicker video transmission. This may be the result of a new type of microwave circuit that was designed at Chalmers University of Technology. The research team behind the circuits currently holds an attention-grabbing record. Tomorrow the results will be presented at a conference in San Diego.   Every time we [...]

Superconducting Circuits, Simplified

Superconducting Circuits, Simplified

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet’s most popular sites.   Superconducting chips also promise greater processing power: Superconducting circuits that use [...]
