Rigetti Computing has launched the Novera QPU, a 9-qubit quantum processing unit based on their fourth generation Ankaa-class architecture, providing hands-on access to quantum computing technology and accelerating progress in the field.

  • The Novera QPU is based on Rigetti's fourth generation Ankaa-class architecture, boasting tunable couplers and a square lattice for enhanced connectivity and faster 2-qubit operations.
  • The Novera QPU provides hands-on access to quantum computing technology, allowing researchers to gain a head start in their quantum computing endeavors and drive industry progress.
  • The Novera QPU supports universal, gate-based quantum computing, making it an invaluable tool for quantum software and algorithm experts. It enables the prototyping and testing of hybrid quantum algorithms, characterization and error mitigation techniques, and quantum error correction (QEC) experiments.


Rigetti Computing, a leading player in the Quantum Computing space, has launched its latest offering: the Novera QPU. This 9-Qubit quantum processing unit is based on Rigetti’s fourth generation Ankaa-class architecture, boasting tunable couplers and a square lattice for enhanced connectivity and faster 2-qubit operations. Manufactured in Rigetti’s state-of-the-art Fab-1 facility, the Novera QPU represents a significant step forward in the company’s pursuit of full-stack quantum-classical computing.

The Novera QPU comprises a 9-qubit chip with a 3×3 array of tunable transmons, as well as a 5-qubit chip without tunable couplers or qubit-qubit coupling. The latter can be used for developing and characterizing single-qubit operations on a simpler circuit. Other components of the Novera QPU include a puck containing both the 9-qubit and 5-qubit chips, interposers, and a PCB to route signals to SMPM connectors at the puck periphery. A tower hanging from the MXC (mixing chamber plate) facilitates cooling power delivery from the MXC to the chips, while shields surround the tower to shield the puck from infrared radiation and stray magnetic fields. The setup also includes payload brackets, a signal chain, and various signal conditioning devices.

Dr. Subodh Kulkarni, Rigetti CEO, highlights the significance of the Novera QPU, stating that it provides hands-on access to the company’s quantum computing technology. With the same architecture as their 84-qubit Ankaa systems, researchers utilizing the Novera QPU can gain a head start in their quantum computing endeavors and drive industry progress. The Ankaa-class 9-qubit QPUs have already been commissioned by national labs, and now this technology is available to those seeking to accelerate their own quantum computing work.

The launch of the Novera QPU not only benefits quantum computing professionals and students but also enables organizations to tap into years of Rigetti’s internal R&D within a matter of weeks. Rigetti’s extensive experience in full-stack quantum computing technology, spanning over a decade, positions them to equip the quantum computing ecosystem with top-notch hardware and engineering.

The Novera QPU supports universal, gate-based quantum computing, making it an invaluable tool for quantum software and algorithm experts. It enables the prototyping and testing of hybrid quantum algorithms, characterization and error mitigation techniques, and quantum error correction (QEC) experiments. Additionally, organizations looking to develop various components of their quantum computing stack can leverage the Novera QPU to accelerate areas such as control electronics and software, QEC decoders, control optimization algorithms, native gate architectures, and measurement and calibration, along with accompanying software.

Designed to seamlessly integrate with commercially available dilution refrigerators and control systems, the Novera QPU offers a user-friendly experience. It is now available for order on Rigetti’s website, starting at $900,000. Once an order is confirmed and shipping logistics are finalized, customers can expect delivery within 4-6 weeks. This accessibility and quick turnaround time further solidify Rigetti’s commitment to driving progress in the quantum computing field.

Technology Explained


PCB: Printed Circuit Boards (PCBs) are the backbone of the modern computer industry. They are thin boards made of a non-conductive material, such as fiberglass, with a thin layer of copper on top. This copper layer is etched with a pattern of electrical pathways that connect the various components of a computer together. PCBs are used in almost every electronic device, from computers to cell phones, and are essential for the functioning of these devices. They provide a reliable and efficient way to connect the components of a computer, allowing for faster and more reliable communication between them. The use of PCBs has revolutionized the computer industry, allowing for smaller, faster, and more reliable computers.


Quantum Computing: Quantum computing is a type of advanced computing that takes advantage of the strange behaviors of very small particles. It's like having a supercharged computer that can solve incredibly complex problems much faster than regular computers. It does this by using special "bits" that can be both 0 and 1 at the same time, which allows it to process information in a very unique way. This technology has the potential to make a big impact in areas like data security and solving really tough scientific challenges, but there are still some technical hurdles to overcome before it becomes widely useful.


Qubit: Qubit is a unit of quantum information that is used in quantum computing. It is the smallest unit of information that can be stored and manipulated in a quantum computer. A qubit can represent a 0, 1, or both 0 and 1 simultaneously, which is known as a superposition. This allows quantum computers to process and store information much faster than traditional computers. The applications of qubits in the computer industry are vast, ranging from cryptography and artificial intelligence to drug discovery and financial modeling. By harnessing the power of quantum computing, businesses can solve complex problems faster and more efficiently than ever before.
