Physical Qubits
Physical qubits are the basic building blocks of quantum computers, representing quantum analogues to classical bits. However, these qubits are highly susceptible to noise, electromagnetic interference, and temperature fluctuations, resulting in high error rates.Logical Qubits and Error Correction
To solve real-world problems reliably, quantum computers must use logical qubits, which bundle many physical qubits together under sophisticated error correction schemes. This redundancy enables accurate and reproducible results.- Practical implication: The road to practical quantum computing is paved by progress in logical—not just raw—qubit counts. Each logical qubit may require dozens or even hundreds of physical qubits, depending on error rates and error correction capabilities.
Level 2 and Fault Tolerance
Operational Level 2 quantum computers, like Microsoft’s new system, mark a decisive threshold. They are able not only to perform quantum computations but to detect, correct, and recover from some errors during those computations, bringing us closer to fault-tolerant quantum systems.AI, Quantum, and the Modern Cloud: Synergies and Challenges
