Author: [Generated for illustrative purposes] Date: April 14, 2026 Subject: Quantum Computing & Cloud Infrastructure Abstract The advent of cloud-based quantum computing has democratized access to quantum hardware, allowing researchers, educators, and enthusiasts to run quantum algorithms without owning expensive, cryogenically cooled machines. This paper explores the ecosystem of free quantum computing clouds, focusing on major providers (IBM Quantum, Amazon Braket, D-Wave Leap, and Chinese platforms). It analyzes the underlying system architecture, the trade-offs of free access (e.g., limited qubits, queuing priority, coherence time), and the educational and research impact. Finally, we discuss the sustainability of free-tier quantum services and propose a roadmap for equitable future access. 1. Introduction Classical cloud computing revolutionized IT by offering scalable resources on demand. Quantum computing (QC), still in the Noisy Intermediate-Scale Quantum (NISQ) era, requires extreme environments—millikelvin temperatures, vibration isolation, and complex control electronics. No individual university or startup can easily afford a 50+ qubit system.
