FAQs
What quantum algorithms are you exploring at the moment?
We actively investigate various quantum algorithms including optimization, simulation and quantum machine learning. Our experts create hardware-efficient algorithms including error-mitigation techniques which allows us to get the best performance out of our NISQ hardware.
For example, we have already significantly improved the performance compared to existing state-of-the-art routing algorithms for QAOA (Quantum Approximate Optimization Algorithm) circuit. See our paper for more details. More benchmark metrics will follow as we continue running experiments on IQM systems.
How do I integrate a quantum computer in an existing high-performance computing environment?
Together with our HPC customers, we have tested different deployment architectures to maximize the performance of the hybrid classical-quantum systems. We developed a concept of a specialized system-wide resource manager to focus specifically on the quantum workloads and their complexities. As the algorithms require the input of a classical computation to happen within the lifetime of the qubits, an on-premises integration can reduce network latency and facilitate larger scale computations in the NISQ (Noisy Intermediate-Scale Quantum) era. For more details, see our Whitepaper.
What are the latest performance benchmarks of IQM hardware?
With our latest benchmarks measured on the 20-qubit quantum computer, we have demonstrated a median two-qubit (CZ) gate fidelity of 99.51% across 30 qubit pairs, with maximum fidelity over a single pair reaching as high as 99.8%.
Among the system-level benchmarks IQM obtained:
- Quantum Volume (QV) of 25=32
- Circuit Layer Operations Per Second (CLOPS) of 2600.
- 20-qubit GHZ state with fidelity greater than 0.5.
- Q-score of 11
