To ensure network performance and stability, onsite network engineers use software to monitor more than 300 data points every second, 24/7/365. Customers can generate, distribute and measure qubits across EPB Quantum Network’s dedicated fiber optic cable using the latest foundational quantum equipment.

  • Photonic qubit sources
  • 4 parallel qubit channels
  • Single photon counting detectors
  • Quantum-compatible fiber optic switches
  • Integrated automatic polarization control
  • Flexible network architecture
  • Dedicated fiber optic lines for distributing qubits
  • Precision timing
  • Network configuration software

“The quantum industry continues to rapidly evolve as new applications continue to be discovered, ranging from accelerating drug development, to quantum sensors that can give advanced earthquake warnings, to optimized truck routing that can notably lower greenhouse gas emissions,” said Qubitekk President, Co-Founder and CTO Dr. Duncan Earl. “EPB Quantum Network is responsive to the diverse needs of quantum innovators, whether customers are running existing applications, testing new quantum technologies or validating equipment performance. The strength of EPB Quantum Network is that all customers, no matter their size or sector, can tap into the resources offered by the network to quickly enable their applications and test their quantum products.”

EPB works with prospective customers to design options for various use cases and offer subscription packages tailored to diverse needs to support the goals of customers developing new products, proving investment readiness, seeking grant funding or conducting equipment testing.
