Full error correction is years away, so noisy quantum computers rely on error mitigation instead. This article explains zero-noise extrapolation, probabilistic error cancellation, and the rest of the toolkit — plus the landmark 127-qubit experiment that proved mitigation works.
In 2000, David DiVincenzo distilled the requirements for a working quantum computer into five criteria. This article walks through each one, the two bonus criteria for quantum communication, and how today’s superconducting, ion-trap, and neutral-atom platforms stack up.
An honest head-to-head of the two quantum computing paradigms: how annealing and gate-based machines work, where each genuinely shines, and the real trade-offs in universality, error correction, and evidence of speedup.
Build Bell pairs with two gates, see why they cannot be factored into independent qubits, and walk through the teleportation protocol step by step — including a complete Qiskit circuit and why it breaks no laws of physics.
How quantum phase estimation extracts hidden phases from unitary operators: the phase-kickback trick, a worked T-gate example in Qiskit, and how Shor’s algorithm turns an eigenvalue into factored integers.
Qubits are fragile, and physics forbids copying them. Here is how quantum error correction protects quantum information anyway — from Shor’s 9-qubit code to Google’s Willow breakthrough.
