SAXON Q Reports That Room-Temperature Quantum Computers Can Rival the Performance of Superconducting Processors

Insider Brief

• SAXON Q reported that its room-temperature diamond quantum computer achieved 77.3% success in a three-qubit Grover search, close to the cited superconducting benchmark of 78%.
• The system achieved 87% success when searching for two targets among eight items, with both tests exceeding the classical success limits cited in the paper.
• Researchers conducted the benchmark at Fraunhofer IWU in Dresden using a previous-generation system that consumes roughly 600 watts and requires no cryogenic cooling or vacuum equipment.

PRESS RELEASE — — SAXON Q, a leader in NV-center quantum computing, today released a paper showing that its room-temperature diamond-based system can perform on par with superconducting quantum computers cooled to near absolute zero.

Running Grover’s search algorithm, a standard benchmark test for quantum performance, a SAXON Q system identified a single target state 77.3% of the time using three qubits, rivaling the best published superconducting result of 78%, which required a temperature roughly 15,000 times colder.

“The assumption in quantum computing has been that you trade performance for convenience. These results show that tradeoff isn’t necessary,” said Marius Grundmann, co-founder and CEO of SAXON Q. “Our system ran a complete quantum algorithm in an ordinary room at a customer site, and the results were similar to those of machines that require extensive infrastructure to cool them to near absolute zero.”
