Such improvements substantially reduce the quantum resources that useful applications require, so practical quantum computers could arrive sooner than previously anticipated.
(Similar to ordinary computers, quantum computers work by applying a long sequence of simple operations, called gates, to their qubits.
At one extreme, a quantum circuit can uncompute intermediate results as soon as they have been used.
This is what makes quantum circuit design an especially interesting test of Claude’s capabilities.
So, we asked Claude to design a more efficient quantum circuit for the decoding step.
