The power of quantum computation derives from algorithmic methods that exploit the availability of quantum superposition and entanglement to perform computations that are intractable with classical devices.The race is on to develop hardware that will unleash the promise of quantum algorithms.A handful of different types of hardware are currently being developed with the greatest efforts directed at superconducting,quantum-dot,trapped-ion,photonic,and neutral-atom approaches [1].While all approaches have strengths and weaknesses,and are at different stages of development,the challenge of creating a practical design that can be scaled to a million or more qubits has not yet been met with any of the existing platforms.
