Energy risk analysis with Dynamic Amplitude Estimation and Piecewise Approximate Quantum Compiling

Understand

We generalize the Approximate Quantum Compiling algorithm into a new method for CNOT-depth reduction, which is apt to process wide target quantum circuits.

• Combining this method with state-of-the-art techniques for error mitigation and circuit compiling, we present a 10-qubit experimental demonstration of Iterative Amplitude Estimation on a quantum computer.
• The target application is the derivation of the Expected Value of contract portfolios in the energy industry.
• In parallel, we also introduce a new variant of the Quantum Amplitude Estimation algorithm which we call Dynamic Amplitude Estimation, as it is based on the dynamic circuit capability of quantum devices.
