Part 2/6:
The core functionality of quantum computers relies on qubits, the fundamental units of quantum information processing. With both the Zon E3 and Google's recent quantum chip, Willow, featuring 105 qubits, they are comparable in terms of qubit count. However, the critical challenge facing quantum computing remains the issue of noise; fluctuations in the environment can rapidly degrade a quantum computer's processing capabilities. This means that during complex computations, the machine may lose track of values and have to reset, significantly hindering performance.
