Qblox makes quantum computers scalable

The power of quantum computers is often seen as holding the key to overcoming great challenges that society faces in areas such as the energy transition, health, safety and the supply of new materials.

But in the race towards stable and commercially viable quantum systems, there are several doubts about scalability and correction of computational errors. And this is where Qblox comes into play, with the launch of the new generation of qubit control hardware, the Cluster series.

The quantum processor is a chip of less than 1 cm on which calculations are performed. This contains quantum bits (qubits), the building blocks of the quantum processor, fragile and extremely sensitive to imperfections in control signals. This makes it extremely complex to effectively control even a handful of qubits. Current quantum computer prototypes use off-the-shelve electronics, but this is not a scalable approach due to cost, size and complexity limitations, requiring meters of space for the control stack.

Qblox therefore focuses on the realization of an electronics with control stack optimized for a quantum computer. Qblox technology is a factor of 100 times smaller, flexible and cheaper than it acts as a milestone where the input of a classical computer is converted into signals that control the quantum processor.

The new Qblox Cluster is the modular and scalable 19 ″ rack system that has the ability to control up to 20 qubits from a single device. The Cluster is developed with proprietary technologies to allow developers to have dedicated qubit control equipment that offers great scalability, ultra-low signal noise and low latency feedback.

And by cascading multiple Cluster systems together, it leads to integrated quantum control capabilities for an unprecedented number of qubits. Qblox Cluster thus opens the doors to the realization of a macro impact on a global level. The advantages are therefore a small format and a low cost; high quality signal control; flexible execution and modular architecture.

“With a dedicated team of scientists, engineers and developers, we are pushing quantum technology to support scientists around the world with our equipment control of scalable, low-latency qubits, ‘explains the team.

“We are suppliers of quantum control stacks that can be integrated with our customers’ quantum computers. Our company is based in the Netherlands and is a spin-off of the leading quantum institute QuTech, which it allows us to implement the latest scientific insights and take a pioneering position in the worldwide race towards the quantum advantage ».
