Digital-analog quantum algorithm for the quantum Fourier transform

Understand

Quantum computers will allow calculations beyond existing classical computers.

• However, current technology is still too noisy and imperfect to construct a universal digital quantum computer with quantum error correction.
• Inspired by the evolution of classical computation, an alternative paradigm merging the flexibility of digital quantum computation with the robustness of analog quantum simulation has emerged.
• This universal paradigm is known as digital-analog quantum computing.
