• Abstract: The Blind Quantum Computation (BQC) is a delegated protocol, which allows a client to rent a remote quantum server to implement desired quantum computations, while keeping her inputs, outputs and algorithms privacy. However, the qubit errors during the quantum computation are realistic issues that are needed to consider. In this paper, we propose a fault-tolerant blind quantum computation protocol with quantum error-correcting codes to avoid the accumulation and propagation of qubit errors during the computing. Meanwhile, we also present the $\epsilon$-blindness in our protocol. To improve the error correction performance, the concatenated codes are used in our protocol. We further present the resources consumption of photon pulses by the optimal level concatenation codes. The simulation results show that our scheme not only can improve the preparation efficiency but also reduce quantum resources, which shows a significant improvement to a realistic fault-tolerant BQC.

  We show that fault-tolerant logical operations can be performed with constant time overhead for a broad class of quantum codes. We prove that the deviation from the ideal measurement result distribution can be made exponentially small in the code distance. Our work sheds new light on the theory of fault tolerance, potentially reducing the space-time cost of practical fault-tolerant quantum computation by orders of magnitude.

  We study the problem of decoding quantum information encoded in the groundspaces of topological stabilizer Hamiltonians.

For every quantum channel $T$ and every $eps>0$ there exists a threshold $p(epsilon,T)$ for the gate error probability below which rates larger than $C-epsilon$ are fault-tolerantly achievable. Our results are relevant in communication over large distances, and also on-chip, where distant parts of a quantum computer might need to communicate under higher levels of noise.
