Original Abstract Submitted

this disclosure relates to processing encoded quantum information in a quantum computer using a stabilizer quantum error correction code. multiple physical data qubits operable in a stabilizer quantum error correction code. a first quantum circuit operates on the multiple physical data qubits and comprises a physical non-clifford gate to initialise physical states of the multiple physical data qubits in a logical block of the stabilizer quantum error correction code, to define an encoded quantum state encoded by the physical data qubits in the logical block. a second quantum circuit operates on the encoded quantum state and on encoded quantum information and comprises only one or more logical clifford gates to realise, by taking the encoded quantum state as an input, a logical non-clifford gate on the encoded quantum information. as a result, the overhead is significantly reduced compared to alternative approaches, such as magic-state distillation.
