Abstract: The disclosure is directed to implementing a quantum error correction code via a quantum computer that includes a set of functional qubits and a set of non-functional qubits. A set of gauge operators is formed. A set of gauge operator combinations are determined from the set of gauge operators. Determining the set of gauge operator combinations may be based on a subset of functional qubits and a global sequence of each gauge operator. Each gauge operator combination has a composite operator that commutes with the composite operator of each other gauge operator combination. A set of composite stabilizers may be generated. Each composite stabilizer corresponds to a separate gauge operator combination. The QEC code may be executed, via the QCS, based on the set of composite stabilizers.

Abstract: Dynamically reconfigurable architectures for quantum information and simulation are provided. A plurality of neutral atoms is provided. Each neutral atom is disposed in a corresponding optical trap. Each of the plurality of neutral atoms is prepared in a mF=0 clock state. A pair of neutral atoms of the plurality of neutral atoms is entangled by directing a laser pulse thereto. The laser pulse is configured to transition the pair of neutral atoms through a Rydberg state. The optical trap corresponding to at least one neutral atom of the pair is adiabatically moved, thereby moving one atom of the pair relative to the other atom of the pair without destroying entanglement of the pair.

Abstract: A method and apparatus for transmitting information through a topological quantum error correction system based on multi-space-time transformation including steps of initializing quantum information, detecting an error in quantum information transmission, correcting the error in quantum information transmission, and decoding the information in quantum information transmission. Information safety is improved and only a quantity of devices for generating quantum states needs to be increased. A stabilizer is used to analyze code symmetry, for error detection, measurement, and correction. Any information about an encoded qubit is not revealed during odd/even parity measurement, so that an encoding state of the encoded qubit remains unchanged. A double-layer convolutional neural network model in an adversarial network can find an error correction chain with a best effect.
