The core issue is wiring. Each added qubit needs more control and readout lines inside a dilution refrigerator, and those lines are limited. SemiQon and NQCP are testing whether cryogenic multiplexers can share that limited port count across more qubits per cooldown. Readers should treat this as early validation work, not a demonstrated scaling result.

SemiQon and NQCP test multiplexers for more qubits per cooldown.
Quantum Zeitgeist3 min read
SemiQon & NQCP are validating cryo-optimized CMOS multiplexers, addressing the limited RF ports that hinder measuring more qubits in a single cooldown.
SemiQon has begun testing multiplexer chips within the NQCP Spin Qubit Pilot Line, a collaboration initiated in October 2025, to address a critical limitation in quantum computer development. A limited number of microwave and RF ports on dilution refrigerators hinders the measurement of increasing numbers of qubits in a single cooling cycle. “Every additional qubit multiplies the wiring problem inside…
