A recent publication from the Strontium Rydberg Experiment group highlights a promising advancement for fault-tolerant quantum computing (see also the related post on the MQV webpage). The work introduces a novel metastable fine-structure qubit based on the long-lived clock states of strontium-88, positioning it as a strong candidate for scalable quantum architectures.

This approach combines high-fidelity universal gate operations with the intrinsic stability of atomic systems. Notably, by deliberately excluding the ground state from the qubit subspace, leakage errors can be systematically converted into erasure errors - making them significantly easier to detect and handle during computation.

In addition, spin-selective mapping within the qubit manifold enables state-resolved readout and post-selection of successful computational outcomes. Together, these features mark an important step toward robust, error-corrected quantum processors based on neutral atoms.

We are delighted to welcome planqc as an official member of our consortium!

Led by Fabian, the team of three with Luna and Kai will focus on advancing the control software for the MUNIQC-Atoms demonstrator, further strengthening its capabilities. In close collaboration with LRZ, planqc will also support the integration of the demonstrator into the existing ecosystem.

We look forward to this collaboration and the expertise planqc brings to the project.

Founded by two passionate doctoral students from Heidelberg, Linq is on a mission to revolutionize quantum computing. At the core of Linq's innovation lies integrated photonics – a crucial technology. This approach promises to shrink the physical footprint of quantum computers while enhancing their performance and feasibility for real-world applications.
