Geometry-derived control pulses for low-error quantum gates
This technology provides a mathematical method for generating control signals that make quantum computers operate more accurately despite real-world noise and errors. It works by mapping the desired quantum gate operation onto a geometric curve in space, then using the shape of that curve to calculate precise electromagnetic pulses that drive the quantum hardware. Because the error-correction is baked into the geometry of the pulse design itself, the resulting gates are inherently more robust without requiring additional overhead circuits. This is a software-level method that runs on classical computers to produce better instructions for quantum processors.
What you could build
A pulse-engineering software library or compiler module sold to quantum hardware companies and cloud quantum computing platforms to improve gate fidelity out of the box; primary buyers would be quantum hardware OEMs and quantum-as-a-service providers.
Who in Virginia should care
Northern Virginia defense and intelligence contractors (e.g., Leidos, Booz Allen, MITRE) pursuing quantum computing capabilities for secure computation, plus AWS and Microsoft quantum cloud teams with Virginia data center presence.
Readiness: Lab validated
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
