• Abstract summary: We report the implementation of a perceptron quantum gate in an ion-trap quantum computer. In this scheme, a perceptron's target qubit changes its state depending on the interactions with several qubits. The applicability can be generalized to higher-dimensional gates as well as the reconstruction of arbitrary bounded continuous functions of the perceptron observables.

• Abstract: We report the implementation of a perceptron quantum gate in an ion-trap quantum computer. In this scheme, a perceptron's target qubit changes its state depending on the interactions with several qubits. The target qubit displays a tunable sigmoid switching behaviour becoming a universal approximator when nested with other percetrons. The procedure consists on the adiabatic ramp-down of a dressing-field applied to the target qubit. We also use two successive perceptron quantum gates to implement a XNOR-gate, where the perceptron qubit changes its state only when the parity of two input qubits is even. The applicability can be generalized to higher-dimensional gates as well as the reconstruction of arbitrary bounded continuous functions of the perceptron observables.

  The intrinsic quantum gates refer to the class of natural-forming transformations in the qubit rotating-frame under direct exchange coupling. We develop a general formalism for identifying the multi-qubit intrinsic gates under arbitrary array connectivity. The applications of the intrinsic gates in quantum computing and quantum error correction are explored.

  We show that a measurement can turn a non-interacting system with only single-qubit control into a two- or multi-qubit entangling gate. The gate works by a geometric phase on the system, conditioned on it lying within a particular nonlocal subspace. We show that the gate is viable for implementation in circuit and cavity QED systems.

• Influence of errors on the transport of quantum information through distant quantum dot spin qubits [0.0]
  We model the quantum dot spin qubits by a spin chain with nearest-neighbors interaction. Within this model, we can perform the interaction of distant qubits by the action of consecutive SWAP gates. The order of the SWAP and CNOT gates is important and it can lead to a relevant difference in fidelity when the number of qubits is large.
