Summary
Quantum computers today are limited by how qubits talk to each other — interconnects. Lucas and Luna explore the interconnect bottleneck: why superconducting qubits can't just 'wire up' like classical chips, the challenge of crosstalk and signal degradation at millikelvin temperatures, and how companies like IBM, Google, and startups like Rigetti are tackling it with cryogenic cabling, photonic links, and multiplexed control. They dive into a specific 2025 paper from the Delft team showing a 10x improvement in qubit connectivity using a novel impedance-matched interconnect. The episode makes the case that interconnects, not qubit count, may be the real gating factor to fault-tolerant quantum computing. #QuantumComputing #Interconnects #Qubits #CryogenicCabling #PhotonicLinks #IBMQuantum #GoogleQuantum #Rigetti #SuperconductingQubits #Crosstalk #Millikelvin #Delft #FaultTolerant #Technology #FexingoBusiness #BusinessPodcast #QuantumHardware #SignalIntegrity Keep every episode free: buymeacoffee.com/fexingo
