The Massively Scalable Control Architecture for up to 100s of qubits, from Ultrastable DC to 18.5 GHz

In the worldwide race towards quantum computers with groundbreaking applications, challenges have to be overcome:

1) improving the quality of qubits and operations, 2) scaling up the number of qubits, 3) harnessing algorithms with quantum error correction and error mitigation strategies.

Crucial in quantum computing is the control stack that generates control signals and interprets algorithm outcomes.

Qblox overcomes the three challenges by building control stacks that combine unleveled noise performance, a low-latency arbitrary control flow and scalability up to 100s of qubits.

We are supporting quantum revolutions worldwide with our dedicated qubit control equipment and are ready to speed up yours.

Massively scalable qubit control architecture from Ultrastable DC up to 18.5 GHz

Tailored solutions for challenges in the quantum industry, Transmons, Spin qubits, NV-Centers, Topological systems, Trapped ions and Quantum Networking.

A variety of quantum chips are pursued, for instance, based on superconducting circuits, quantum dots, NV centers, trapped ions or topological systems.

In most setups, a quantum chip is hosted in a cryostat to reach a chip temperature close to 0 K in order to suppress noise.

Users interface via a high-level portal to execute a quantum algorithm. The Qblox control stack is required to translate the high-level calibration routines and algorithms to specific low-level analog signals.

Signals are finally sent back to the Qblox control stack and retranslated into digital outcomes for analysis and interpretation.



The Cluster and Pulsar Series are the ideal modular hardware choice for quantum setups scaling from a handful towards 100s of qubits. Control and readout tasks are assigned to different modules which operate at the baseband (0-300 MHz) or in the microwave regime (2-18.5 GHz). Its fully-integrated design avoids crosstalk and signal interference, together with the Open-source software platform Quantify it ensures easy operations and optimized arbitrary control flows.

Guided by our proprietary SYNQ and LINQ backplane system protocols all signals are fully synchronized and can run arbitrary control flows with low-latency data sharing.

For few-qubit setups, we offer the standalone operable Pulsar modules. Equipped with the same Qblox technology as found in our Cluster Series, the portable size of the Pulsar QCM and Pulsar QRM is ideal for quickly setting up tests and experiments and replacing voluminous non-dedicated lab equipment.
