Picosecond pulses test limits of dissipationless superconducting currents
Original: Picosecond current pulses probe intrinsic limit for dissipationless transport in superconductors
Researchers have used picosecond current pulses to probe the intrinsic limit of dissipationless transport in superconductors, testing how fast and how intensely resistance-free currents can be driven before superconductivity breaks down. The work, published in Nature, offers a way to measure fundamental switching limits directly on ultrafast timescales, with potential relevance for high-speed superconducting electronics and quantum computing hardware.
Why now: A new Nature study pushes understanding of the fundamental speed limits of superconducting electronics, a topic of growing interest for quantum computing.
