    Why does the VQE algorithm work well on noisy quantum circuits?

    Asked on Sunday, Oct 26, 2025

    The Variational Quantum Eigensolver (VQE) algorithm is particularly effective on noisy quantum circuits because it leverages hybrid quantum-classical optimization to find the ground state energy of a …

    How does decoherence differ between trapped ions and superconducting qubits?

    Asked on Saturday, Oct 25, 2025

    Decoherence in quantum systems refers to the loss of quantum coherence, where a system transitions from a quantum to a classical state. Trapped ions and superconducting qubits experience decoherence d…

    How do logical qubits protect against bit-flip and phase-flip errors?

    Asked on Thursday, Oct 23, 2025

    Logical qubits are designed to protect against bit-flip and phase-flip errors by encoding a single logical qubit into multiple physical qubits using quantum error correction codes. These codes detect …
