Quantum Open Architecture (QOA) & Quantum Systems Integration: From Monoliths to Modular Quantum Computing
Today's quantum computers are monoliths — a single vendor designs the chip, builds the control electronics, writes the software, and operates the cloud platform. The customer gets a black box. This is exactly where classical computing was in the 1960s,…

Inside Quantum Computing’s Modular Revolution – Discussion with QuantWare’s CEO Matt Rijlaarsdam
Quantum computing is entering a new phase where scaling up isn’t just about qubit counts - it’s about how those qubits are built and integrated. A recent discussion with QuantWare’s CEO, Matt Rijlaarsdam, shed light on “quantum open architecture” (QOA)…

Engineering the Quantum Operating System (OS) Stack: From Nanosecond Pulse Control to System-Level Orchestration
The argument for quantum computing's "PC moment" has become surprisingly compelling. QuantWare ships superconducting QPUs to customers in 22 countries. Qblox sells modular control stacks to over 100 labs. Bluefors has installed 1,800 cryogenic systems worldwide. The Quantum Open Architecture…

Quantum Open Architecture (QOA): The “PC Moment” of Quantum Computing
Today, a sea change is underway. Quantum Open Architecture (QOA) is doing for quantum computing what the PC revolution did for classical computing - opening up the ecosystem. Just as the computing world shifted from monolithic mainframes to modular PCs…

Quantum Systems Integration
Quantum Systems Integration (QSI) refers to the holistic process of designing, assembling, and deploying quantum computing systems and ensuring they work seamlessly with classical systems. In simpler terms, a quantum systems integrator is like a general contractor for quantum projects…

The Nervous System of Quantum Computing: A Deep Dive into Quantum Control Systems
In July 2025, Keysight Technologies shipped a piece of equipment to a research institute in Tsukuba, Japan, that most people outside the quantum industry had never heard of - yet without it, the 1,000-qubit quantum computer it was destined for…

Quantum-as-a-Service (QaaS)
Quantum-as-a-Service (QaaS) - also called Quantum Computing as a Service (QCaaS) - is essentially cloud-based access to quantum computing resources. In simple terms, a third-party hosts quantum computers (and related software tools) in the cloud, and users access those quantum…

The Quantum Computer That Breaks Your Encryption Won’t Be a Single Chip
There's a question that has quietly bothered me for years, one the quantum computing industry has mostly avoided asking out loud: why are we trying to build a quantum computer the way we stopped building classical computers fifty years ago?…
