Cisco has revealed the Universal Quantum Switch, a prototype designed to route entangled photons across quantum computers and sensors from different vendors, using standard telecom fiber and operating at room temperature [1]. This isn’t just another lab demo — it’s a direct shot at one of quantum networking’s nastiest scaling bottlenecks. If Cisco’s approach sticks, the market’s longstanding vendor lock-in and infrastructure fragmentation could finally face a credible threat.
