Quantum Bus for a Quantum Computer Based on Spins in Silicon (SPINBUS)

Project funded by Research Council of Finland, grant 335460. Participating organisations named by the source: Aalto University. Funded amount: EUR 159,943, as stated by the source. Runs 2020-09-01 to 2022-08-31. Keywords: Physical sciences. Source: OpenAIRE Graph, from the funder's project data (collected by OpenAIRE on 2026-07-23); national funding data, not CORDIS. Abstract given by the source: Issues related to scalability remain the last Achilles heel in realizing a solid-state quantum computer. The problem lies in the difficulty in making individual quantum bits, or qubits, communicate with one another over distances required for quantum computation. We develop a novel silicon-based quantum information bus that not only mitigates this issue but also greatly alleviates spatial constraints of the qubit placement on chip. In addition, the device allows the study of non-classical electron transport that has been theoretically predicted but never been observed. This represents a beakthrough that will enable high-fidelity transfer of quantum information encoded in electron spins, opening doors for novel applications in quantum electronics. This project will ultimately lead to quantum supercomputers that will drive the next quantum revolution, fundamentally impacting the fields of computing, security, telecommunications, medicine, materials, and artificial intelligence.
