Cryogenic Interconnect

Zheng Yuan Quantum announced on November 10 a nearly RMB 100 million angel round backed by Shenzhen Capital Group, Pudong Venture Capital, Dening Capital and others, with proceeds aimed at a 1000-qubit superconducting quantum computer and validation of 3D packaging, cryogenic interconnect and integrated control electronics. The piece notes that experiments have shown logical error rates falling as error-correction scale grows, but packaging, wiring and readout engineering remain the key bottleneck from chip to full system.
