Intel, QuTech Demonstrate Advances in Solving Quantum Interconnect Bottlenecks
Intel and QuTech – a collaboration between Delft University of Technology and the Netherlands Organisation for Applied Scientific Research – published key findings in quantum research to address the “interconnect bottleneck” that exists between quantum chips that sit in cryogenic dilution refrigerators and the complex room-temperature electronics that control the qubits. The innovations were covered in Nature, the industry-leading science journal of peer-reviewed research, and mark an important milestone in addressing one of the biggest challenges to quantum scalability with Intel’s cryogenic controller chip Horse Ridge.
“Our research results, driven in partnership with QuTech, quantitatively prove that our cryogenic controller, Horse Ridge, can achieve the same high-fidelity results as room-temperature electronics while controlling multiple silicon qubits. We also successfully demonstrated frequency multiplexing on two qubits using a single cable, which clears the way for simplifying the ‘wiring challenge’ in quantum computing. Together, these innovations pave the way for fully integrating quantum control chips with the quantum processor in the future, lifting a major roadblock in quantum scaling,” says Stefano Pellerano, principal engineer at Intel Labs
