Is Noise the Biggest Problem for Quantum Computing?
The physical design and implementation of a qubit can interfere with the next level of abstraction due to the noise in today's quantum computers. The current quantum computers are very noisy, causing the qubits to be far from perfect, leading to interference between lower and higher levels. The goal is to achieve error-corrected quantum computers where the qubits behave like perfect abstract qubits for as long as required. The fundamental problem in building a quantum computer is decoherence, which is the unwanted interaction between the qubits and the external environment.
