Quantum Storage vs Classical Storage: A Complete Comparison When we think about storage in computers today, we picture hard drives, SSDs, or RAM —devices that can store vast amounts of data reliably, even when the power is off. Quantum computers, however, work very differently. Their “storage” is not about gigabytes or terabytes but about holding fragile quantum states for computation. Let’s break down the comparison. 📦 Classical Storage Today Models Used: HDDs (hard disk drives), SSDs (solid-state drives), DRAM (memory), and long-term archival (magnetic tape, optical discs). Capacity: Terabytes to petabytes are common in enterprise systems, with exabyte-scale storage networks available. Persistence: Data remains intact even when the power is turned off. Environment: Operates at room temperature , requiring no special cooling for everyday use. Standby: Files can sit untouched for years without loss, unless physical damage or degradation occurs. Example: A 1...

Quantum Operating Systems: How IBM, IQM, and D-Wave Run the Computers of the Future When we think of operating systems, names like Windows, macOS, or Linux usually come to mind. In quantum computing, however, the machines are so different from regular computers that each company designs its own specialized operating system to control the hardware. Three companies— IBM, IQM, and D-Wave —are already running operational quantum data centers, and each has built its own unique system for managing and programming their quantum processors. Let’s explore how each one works and why it matters. 🔹 IBM Quantum – Qiskit Runtime What It Runs On: IBM develops gate-based superconducting quantum computers , one of the most widely used models in research and industry today. Operating System / Stack: Qiskit Runtime is IBM’s operating system layer, built to optimize and execute quantum programs. Developers use the Qiskit SDK (a Python-based toolkit) to write quantum applications. P...

The Top 3 Quantum Companies Already Running Operational Data Centers Quantum computing is no longer a far-off dream—it’s here, operating in real data centers around the world. While many startups are still in the experimental phase, a handful of tech leaders already run fully operational quantum systems , powering research, industry pilots, and cloud access for companies and universities alike. Let’s look at the Top 3 companies leading the way , where their quantum data centers are located, and the systems they’re running right now. 1. IBM Quantum – The Global Pioneer Operational Data Centers: Poughkeepsie, New York (USA) – Home to multiple utility-scale processors including Eagle (127 qubits) and the newest Heron processors. Ehningen, Germany (Europe) – The first European IBM Quantum Data Center, already live with ibm_strasbourg and ibm_brussels (Eagle-class) and preparing ibm_aachen (Heron-class). San Sebastián, Spain (coming late 2025) – Will host an IBM Quan...
