Quantum states are continuous and therefore errors are continuous. In principle, it could take in nite resources to determine exactly what the error is. Measurement destroys the superposition of quantum data, but the only way to extract the error syndrome bits is to measure. Therefore, we can only measure indirectly.

Quantum Computing Systems & Architecture The study of how to compose quantum computers out of fundamental hardware building blocks (qubit devices and their associated classical control hardware) and various layers of abstraction above the raw hardware.

Research in quantum computing focuses on the development of stable qubits, error correction, quantum gates, and the architecture necessary to scale quantum systems. The challenges here include controlling quantum decoherence and developing algorithms that can fully harness quantum computational power.

Abstract: This paper presents the definition and implementation of a quantum computer architecture to enable creating a new computational device - a quantum computer as an accelerator. A key question addressed is what such a quantum computer is and how it relates to the classical processor that controls the entire execution process.
