Quantum Brilliance GmbH said today it’s ready to begin mass production of its diamond-based quantum computers after closing on a $20 million early-stage round of funding. Today’s Series A round was led by the deep-technology fund Main Sequence, the U.S. venture capital firm In-Q-Tel and the Japanese investor Intervalley Ventures. Other participants include the Australian sovereign wealth funds, National Reconstruction Fund Corp. and Breakthrough Victoria, plus Alium Capital Management, Investible and Jelix Ventures. The startup, which has offices and facilities in Germany and Australia, is pursuing a novel approach to the design of quantum computing hardware, using synthetic diamond-based qubits that can operate at room temperature in any environment. According to the startup, this makes quantum computers much more practical, allowing them to run in data centers, autonomous vehicles, spacecraft and edge computing scenarios. The approach differs considerably from its quantum computing rivals such as IBM Corp. and Google LLC, which have built machines that must be stored within extreme environments or use wildly sophisticated technologies to work properly. In the case of IBM and Google, their quantum computers must operate at temperatures close to absolute zero (−273.15 °C), while IonQ uses an elaborate system of lasers to manipulate trapped ion-based qubits suspended in a vacuum.
