QuantWare, a global leader in quantum hardware scaling technologies, today revealed Contralto-A: a new Quantum Processor Unit (QPU) with complementary offering designed to meet the requirements of its customers wanting to scale their quantum error-correction capabilities.
Contralto-A features up to 17 transmon qubits with tunable couplers, making it almost twice as large as competing solutions that are commercially available. With this size, Contralto-A allows for distance-3 surface code implementations and comes with optional expert training and support from leading hardware and algorithm specialists, helping its customers create and achieve a competitive roadmap towards large scale quantum error-correction capabilities. Contralto-A is a first step on this roadmap and is specifically made to be easily upgradable to larger QPUs powered by QuantWare’s VIO platform.
Contralto-A is designed by quantum error-correction experts and is optimised for running up to a distance-3 surface code. Featuring up to 17 flux-tunable transmon qubits and tunable couplers, the design incorporates advanced components such as tunable couplers and Purcell filters, to enable high-fidelity operations.
Contralto-A comes with optional training and support from QuantWare’s hardware and algorithm experts on both the usage of Contralto-A, as well as support in developing a roadmap towards large scale error correction capable systems scaling beyond Contralto-A. The Quantum Open Architecture compatibility grants its customers hardware-level access at every layer of the stack, providing flexibility and control in quantum system design. It also allows for the integration of preferred or locally sourced components, enabling QuantWare’s customers to configure their system to meet their unique requirements.
Contralto-A offers a cost-efficient upgrade path to QuantWare’s VIO-powered QPUs, ensuring a seamless progression on the customer’s roadmap.
“Our customers want to scale towards error corrected systems and create and achieve a competitive roadmap - and this need has been amplified following the recent announcements of the impressive results of Google’s Willow. With Contralto-A and our roadmap support, we provide our customers with a credible path towards a competitive roadmap and an immediate first step on that roadmap ” - Matthijs Rijlaarsdam, CEO and Co-founder of QuantWare
Contralto-A is currently available to Early Access partners and for pre-order with General Access later in the year. More information can be found here: https://www.quantware.com/product/contralto-a
