Quantifying the quantum gate fidelity of single-atom spin qubits in silicon by randomized benchmarking [PDF]

Journal of Physics: Condensed Matter, 2014
Building upon the demonstration of coherent control and single-shot readout of the electron and nuclear spins of individual 31P atoms in silicon, we present here a systematic experimental estimate of quantum gate fidelities using randomized benchmarking ...

Input states for quantum gates [PDF]

Physical Review A, 2003
We examine three possible implementations of non-deterministic linear optical cnot gates with a view to an in-principle demonstration in the near future. To this end we consider demonstrating the gates using currently available sources such as spontaneous parametric down conversion and coherent states, and current detectors only able to distinguish ...

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Impact of decoherence on the fidelity of quantum gates leaving the computational subspace [PDF]

Quantum
The fidelity of quantum operations is often limited by incoherent errors, which typically can be modeled by fundamental Markovian noise processes such as amplitude damping and dephasing. In Phys. Rev. Lett.

Simulation of the Creation of a Single Quantum Gate to Change the Quantum State of a Photon Using Quarter-Wave Plates

Proceedings of the International Conference on Applied Innovations in IT
The design and simulation of single Pauli gates and Hadamard gates were performed using MATLAB. The Pauli-X gate was constructed using two quarter-wave plates QWP and was evaluated on the quantum states |0⟩ and |1⟩.
