The last years have seen significant advances in the field of quantum technologies, consolidatingthe development of basic requirements for quantum computation. Protecting the quantumcomputation from noise and decoherence has become more topical than ever, challenging andbringing quantum error correction fairly close to the integration into practical quantum computers. To make such an integration viable, the EQUIP project aims at (1) providing radically new solutionsto fault tolerant quantum computation, covering both intermediate and large-scale quantumsystems, and (2) bridging the critical gap between algorithmic solutions and latency-power-scalability constrained hardware designs. To achieve these goals, the project brings togetherinterdisciplinary expertise, extending from the computer science foundations of quantum errorcorrection and fault-tolerant computation, to algorithmic aspects, computer architectures, andhardware designs. The main contributions of the proposed research are as follows. First, theproject will develop optimised low-qubit overhead solutions, suited but not restricted tointermediate scale quantum systems, including application-aware and software-based errormitigation techniques, and flag error correction protocols. Second, for large-scale systems, theproject will develop thoroughly new approaches to accurate and hardware friendly decoding ofquantum low-density parity-check codes, and will explore pioneering approaches relying onquantum polar codes. Third, the effectiveness of the proposed solutions will be demonstratedthrough either their implementation into real intermediate-scale quantum devices and quantumsimulators, or the hardware prototyping of the most promising decoding solutions for large-scaledevices. The ambition of the proposed research is to cover the essential prerequisites forpreparing the European industry for the forthcoming challenge of quantum technologies.
