Guest Post: Quantum Computing’s Transistor Moment

A new paper demonstrating Grover’s search on a room-temperature diamond processor may echo the transistor’s takeover from vacuum tubes – and raises questions about how much vacuum-dependent quantum hardware survives the same transition. Guest Post By Prof. Dr. Marius Grundmann, CEO, SAXON Q Every disruptive technology has a quiet laboratory result that outsiders miss and insiders remember for decades. A newly published demonstration of Grover’s search algorithm on a room-temperature diamond quantum processor is a strong candidate for exactly that kind of moment. The result is narrow in scope – a three-qubit search on a nitrogen-vacancy (NV) center system – but carries a broad implication. It suggests that quantum information processing is echoing the move classical computing made, out of vacuum-based hardware and…
