Researchers at NIST have developed a system that allows commercial electronic components to operate in close proximity with ultra-cold quantum devices, enabling four times more data output with the same number of connected wires. This breakthrough is crucial for advancing quantum computing, as it eliminates the need for long signal paths and reduces heat generation from connecting wires.
The system uses a shift register from room-temperature electronics to control switches that route measurement lines to specific quantum devices, allowing for more efficient data collection without additional wires. This development represents a significant milestone in enabling advanced measurements and technologies at cryogenic temperatures, and has been particularly challenging to achieve during the pandemic.
