Infleqtion, a neutral atom-based quantum technology company, has unveiled early details on the next-generation architecture for its Sqale quantum computer and an updated roadmap. The company expects to deliver a full-stack fault-tolerant system with more than 1,000 logical qubits by 2030. The company has already achieved 12 logical qubits with error detection and loss correction, positioning it ahead of its previous schedule for achieving 10 logical qubits with error correction in 2026.
As a part of this announcement, Infleqtion has successfully executed a logical qubit realization of a pre-compiled variant of Shor’s algorithm, marking the first hardware-based demonstration using logical qubits that reportedly outperformed physical-only qubits on a task with cryptographic relevance. The company also demonstrated a constant-depth CNOT ladder and the initialization of the [[16, 4, 4]] many-hypercube QEC code. A more detailed technical overview of this demonstration is available in a preprint publication on arXiv.
The new architecture, demonstrated on a Sqale QPU with an array of 114 neutral atom qubits, unites qubit motion and in-place entanglement. This advancement is positioned to accelerate Infleqtion’s roadmap toward scalable, fault-tolerant quantum systems by reducing overhead related to qubit motion. Matt Kinsella, CEO of Infleqtion, commented that the company anticipates its systems will make quantum useful for solving real-world problems by the end of this decade. The company’s integrated roadmap spans hardware and software and supports both quantum computing and sensing applications.
