Your fast track to quantum utility

Quantum computing architecture typically consists of layers: the physical quantum chip (holding the qubits), the control plane (electronics), and the software stack, plus the connective wiring linking those layers together. QUB is a modular architecture combining superconducting qubits with autonomous control software to manage the quantum device characterization and calibration.

Not in the traditional sense. Instead of a Central Processing Unit (CPU), they use a Quantum Processing Unit (QPU). While a CPU processes bits (0s and 1s), a QPU manipulates quantum bits (qubits) to perform quantum computation. Quantum computers do depend on CPUs (or GPUs) for classical compute resources that make them useful.

To ensure quantum utility, QUB integrates best-in-class components designed to manage the delicate nature of quantum mechanics and quantum states.

1. The quantum processor (QPU)

At the heart of the QUB is a quantum processing unit utilizing superconducting qubits. Unlike trapped ions, neutral atoms, or quantum dots, superconducting circuits offer fast gate speeds and are manufactured using techniques similar to classical chips, making them highly scalable. In this case, the quantum chip is fabricated by QuantWare with high-coherence superconducting qubits tailored for stability.

2. Control electronics

Qblox provides the computing hardware necessary to manipulate quantum phenomena. Precise electronic pulses control quantum gates and read out probability amplitudes, acting as the bridge between classical computers and the quantum system.

3. Software & error correction

Quantum computers require sophisticated software to manage noise. Q-CTRL provides the operating system that handles quantum error management, optimizing quantum operations to ensure high fidelity. This layer allows users to run quantum algorithms without needing to manually tune quantum gates.

QUB systems represent the internal architecture that the component companies use to validate their individual products. This creates a consistent link between factory testing and deployed performance of all QUB deployments.

QUB is a reference architecture – a blueprint for building quantum hardware. You get a detailed bill of materials for your chosen QUB size, which you can either purchase directly or source through a system integrator. We’ve already confirmed all the components work together taking the uncertainty out of building powerful quantum computers.

The QUB bill of materials is specifically pre-validated because its components are continuously tested together as a system in various validation labs. These specific reference architectures make QUB effective as a fully operational quantum computer. Other vendor components (such as using a different QPU, controller, or software) are still compatible and supported by the QUB’s flexible open architecture; in that case validation and interoperability become the customer’s responsibility.

From financial modeling to molecular simulation and quantum chemistry, the race to unlock quantum computing power is on. Don't let hardware complexity hold you back. QUB offers the quick and cost effective deployment of advanced quantum processing power needed to advance quantum research today.

Quantum supremacy refers to a quantum computer solving a problem classical supercomputers cannot. While QUB is designed to accelerate the path to quantum utility and quantum advantage, it is primarily a platform for developing quantum algorithms, testing quantum error correction, and workforce development in the foreseeable future. Fortunately, it is based on a scalable architecture that will be upgradable to larger QuantWare QPUs using their VIO technology. This means QUB does not achieve quantum supremacy today, but does provide a pathway to quantum supremacy in an effective way.
