Hardware

At Pasqal, we are redefining quantum computing to solve today’s challenges and empower tomorrow’s innovators. Our unique neutral-atom quantum processors (QPU) are designed to bring transformative solutions to industries ranging from finance to healthcare. This brochure is your gateway to understanding how Pasqal’s hardware works, what makes it revolutionary, and how your business can benefit today.

“At Pasqal, we build quantum computers to enable real-world innovation for the challenges of tomorrow.”

The elementary data elements of Pasqal’s Quantum Processing Units (QPUs) – quantum bits or qubits – are laser-cooled Rubidium atoms, individually trapped by tightly focused laser beams, called optical tweezers. The qubits are encoded in the atoms’ electronic states by laser beams and then manipulated using lasers.

The interaction of qubits with light enables access to the finest physical parameters, making our quantum processor a unique tool for creating and controlling complex quantum systems.

It encompasses the following main building blocks:

• The “Optical core” system traps and manipulates atomic qubits as quantum registers for processing tasks.
• The “Pumping system” ensures the ultra-low vacuum level for proper operation of the QPU.
• The “Laser System” and “Control Electronics” enable atomic qubit control, including all necessary laser sources, optical benches, and electronics for configuring, manipulating, and reading the quantum register.
• The “Control computer” manages all operations of the quantum computer and interfaces with the “Host computer,” receiving instructions and sending results.
• The “Thermal Management” system ensures fine thermal management of all the QPU sub-systems,
• The “Power supplies” system provides power to all the sub-systems,
• The “Monitoring” system, composed of a broad range of sensors, is used to check the overall sanity of all the sub-systems and to follow the QPU status
