Reinforcement Learning for Fault-Tolerant Quantum Circuit Discovery (rlftqc)

Welcome to the documentation for rlftqc!

This is a code repository for quantum circuit discovery for fault-tolerant logical state preparation with reinforcement learning.

See the paper here:

Description

This library can be used to train an RL agent for three different tasks:

1. Logical State Preparation: Prepare a logical state from a given stabilizer QEC code.

2. Verification Circuit Synthesis: Prepare a verification circuit from a given logical state preparation circuit based on flag-qubit protocols [1] to make the state preparation fault-tolerant.

3. Integrated Fault-Tolerant Logical State Preparation: Integrates the above two tasks to prepare a logical state fault-tolerantly.

For all the tasks, the user can specify the Clifford gate set and qubit connectivity.
