Qbeat Ventures

Classiq has created a quantum software platform that automates the design of quantum circuits from high-level functional descriptions — analogous to what compilers did for classical computing. Instead of manually placing gates, developers describe what they want the algorithm to achieve, and Classiq's synthesis engine generates optimized circuits. The company raised $45M in Series B funding and has partnerships with IonQ, IBM, Microsoft, AWS, and NVIDIA. Backed by Samsung NEXT and In-Q-Tel (CIA's venture arm).

Quantum Machines develops the OPX+ pulse processor — a purpose-built classical processor for real-time quantum control that handles the precise pulse sequences needed to manipulate qubits. The company's Quantum Orchestration Platform provides low-latency feedback loops essential for error correction. Quantum Machines works across all qubit modalities and has partnerships with major quantum computing labs worldwide. It is part of NVIDIA's NVQLink ecosystem for GPU-QPU integration.

Tabor Electronics is a veteran signal generation company that produces arbitrary waveform generators and RF signal generators used in quantum computing control. With over 50 years in electronic test equipment, Tabor provides the precision waveform generation needed for qubit manipulation. Its Proteus platform offers multi-channel, high-speed arbitrary waveform generation specifically targeting quantum computing and quantum sensing applications.

Arqit develops the QuantumCloud platform for quantum-safe encryption, creating symmetric encryption keys that are computationally secure against both classical and quantum attacks. Unlike quantum key distribution (QKD), Arqit's approach is software-based and can work over existing network infrastructure. The company is publicly listed and has government and defense customers, though its technology claims have faced skepticism from some cryptography experts.
