Adiabatic quantum computing (AQC) has intrinsic robustness to noise, but whether it's fault-tolerant---robust to all forms of noise---has not been explored. While fault tolerance through error correction is theoretically achievable in standard quantum computing, scientists show that it may not be achievable in AQC.

I show how to protect adiabatic quantum computation (AQC) against decoherence and certain control errors, using a hybrid methodology involving dynamical decoupling, subsystem and stabilizer codes, and energy gaps. Corresponding error bounds are derived. As an example, I show how to perform decoherence-protected AQC against local noise using at most two-body interactions.
