Major Quantum Computing Strategy Suffers Serious Setbacks

In 2018, researchers at the forefront of an entirely new approach to building quantum computers published, in the journal Nature, what looked to be a landmark achievement. Existing quantum computers are notoriously fragile, their quantum bits — qubits — prone to incurring random errors. But if the qubits could be made from strange configurations of electrons with the exotic name of Majorana…
