Leveraging Randomized Compiling for the QITE Algorithm

Understand

The success of the current generation of Noisy Intermediate-Scale Quantum (NISQ) hardware shows that quantum hardware may be able to tackle complex problems even without error correction.

• One outstanding issue is that of coherent errors arising from the increased complexity of these devices.
• These errors can accumulate through a circuit, making their impact on algorithms hard to predict and mitigate.
• Iterative algorithms like Quantum Imaginary Time Evolution are susceptible to these errors.
