Prometheus Dynamics is a hardware-aware quantum execution hypervisor. It coordinates compilation, routing, hardware information, and execution decisions so workloads can be mapped to physical processors with greater awareness of the environment they will enter.
Prometheus provides an execution layer around the compilation stack. It connects the logical workload to the physical processor while keeping the implementation details of the execution-selection system protected.
Start with the logical circuit and execution requirements.
Consider multiple compilation and routing paths for the target environment.
Incorporate hardware information into the physical compilation decision.
Send the chosen physical compilation to the QPU and inspect the resulting measurements.
A 9-qubit dense all-to-all graph requires every qubit to interact with every other qubit. On a sparse heavy-hex processor, standard compilers inject massive walls of SWAP gates to force these interactions, destroying the state fidelity. Here is the physical result of using Prometheus instead.
SABRE produced a valid routed circuit using 90 two-qubit gates and a physical depth of 145. Its measured state fidelity in this comparison was 0.5738.
TKET produced a valid physical circuit, but in this benchmark it required 123 two-qubit gates and reached a physical depth of 165. Its measured state fidelity was 0.5248.
Prometheus selected a different physical compilation with 74 two-qubit gates and a depth of 109. That execution produced a measured state fidelity of 0.7466.
The three compilation paths were evaluated through a single SamplerV2 hardware job on IBM Marrakesh rather than through separate jobs taken at different times. This controls for execution-window differences such as changing calibration conditions and timing between runs, keeping the comparison tied to one physical execution record.
SABRE and TKET both produced executable circuits. This benchmark shows a different outcome when the physical compilation selected by Prometheus is executed on the same processor.
The stronger of the two baseline state-fidelity results in this run, with 145 physical depth and 90 two-qubit gates.
The deepest of the three executions at 165 and the highest two-qubit gate count at 123 in this comparison.
Selected a physical compilation with 109 depth and 74 two-qubit gates, while producing the strongest state fidelity, HOP, XEB, and hardware-weighted cost result in this comparison.
This is one physical example from a broader body of comparative experiments. It is not a claim that every workload will produce the same numerical improvement. It demonstrates the problem Prometheus is built to address: the best physical execution is not always completely described by routing cost alone.
Prometheus grew out of an experimental program examining how physical placement, routing cost, hardware conditions, and measured output interact on real quantum processors. The public research record contains five experimental programs, randomized instances, multi-QPU studies, IBM execution evidence, aggregate results, and explicit limitations.
The repository separates individual experiments so hypotheses can be tested under different workloads, scales, topologies, and physical processors.
Prometheus research does not assume that lower routing cost always means better hardware output. The experiments test that relationship directly, look for repeatability across randomized instances, examine scaling boundaries, and compare behavior across IBM Heron processors. The public record also retains mixed and negative outcomes rather than only favorable examples.
View the public research record →Tests whether physical routing cost and observed output-distribution behavior remain coupled on real hardware. One QFT-8 experiment on ibm_kingston showed a more concentrated output despite substantially greater physical routing cost.
Matched randomized QAOA and CrossEnt instances test whether observed behavior survives beyond manually selected circuits.
Sweeps workload size and algorithm family to identify both favorable topological regimes and routing-penalty regimes rather than assuming that extra routing is always beneficial.
A 13-qubit topology-stress benchmark examined whether a substantially different physical realization could avoid the ground-state collapse observed in a depth-optimized baseline.
Related workloads were examined across Fez, Kingston, and Marrakesh to test whether global device statistics are enough to describe the quality of a particular physical execution.
In the randomized-instance study, the same logical problems were independently compiled with SABRE O3, TKET, and Prometheus and executed on the same IBM Heron processor. Prometheus recorded higher measured Hellinger fidelity than SABRE O3 in 30 of 40 matched instances. The result is explicitly described in the research record as evidence that the observed behavior is not confined to a small manually selected set, not as universal superiority.
The research repeatedly tests a narrower proposition: minimizing routing cost alone may be insufficient to predict hardware execution quality.
The research repository is designed as an experimental record rather than a public release of the proprietary Prometheus implementation. It preserves enough evidence to inspect the experiments while keeping the execution-selection mechanism protected.
A quantum workload may be logically identical while its physical execution changes substantially with topology, hardware conditions, compiler choices, and scale. Prometheus exists in the layer where those software and hardware concerns meet.
UPLINK execution endpoints are currently restricted. Contact sales to request free trial access, then submit your workload for comparative evaluation on physical quantum hardware.
Prometheus dispatches comparative jobs through IBM Quantum. An IBM Quantum account may be required for execution, but UPLINK access is separately controlled by Prometheus Dynamics.
