Summary:Weiss et al expresses their views as physicist on the grand challenge towards exerting precise control over a large number of individual quantum particles in quantum computing. Weiss et al states that quantum computation requires preparing atoms in well-defined quantum states, controlling the atoms' interactions to carry out logical operations, and measuring the resulting states to extract the computational result--all while maintaining near-perfect isolation from the environment. They also anticipates that over the next five years several qubit platforms, including neutral atoms, are likely to reach a sufficient size and fidelity that they can perform quantum calculations that cannot be modeled on a classical computer and emphasizes the difficulty to predict how long it will take before a quantum computer is able to factor intractably large numbers.
