Quantum computing without interruptions

Phys · · 432 words · By University

Researchers from Innsbruck and Aachen have demonstrated fault-tolerant quantum computation without mid-circuit measurements, using a trapped-ion quantum processor to run Grover's algorithm on logical qubits. The study, published in Nature Communications, presents a new approach to quantum error correction that could be faster and less error-prone.
