Challenges and Limitations in Quantum Computing
Despite its vast potential, quantum computing faces numerous challenges that must be addressed to realize its transformative impact. The development and implementation of quantum computing technology are hindered by both technical and economic barriers.
Technical Hurdles: Decoherence and Quantum Noise
One of the significant technical challenges is dealing with decoherence and quantum noise. Decoherence occurs when a quantum system loses its quantum properties due to interactions with the environment, causing errors in computation. Quantum noise, on the other hand, refers to the random fluctuations that can affect the state of qubits. As John Preskill noted, "Quantum noise is a fundamental limitation on the performance of quantum computers."

Scaling quantum systems is another significant challenge. As the number of qubits increases, so does the complexity of maintaining coherence and controlling errors.
The Race for More Qubits
The quest for more qubits is a critical aspect of scaling quantum systems. Increasing the number of qubits allows for more complex computations, but it also amplifies the challenges related to decoherence and error correction.
Quantum Volume as a Performance Metric
Quantum Volume is a metric that measures the performance of a quantum computer, taking into account both the number of qubits and the error rates. It's a more comprehensive measure than just the number of qubits, as it reflects the overall capability of the quantum system.
Economic and Accessibility Barriers
Beyond technical challenges, there are significant economic and accessibility barriers. The cost of developing and maintaining quantum computing hardware is extremely high, making it inaccessible to many potential users. As
