IBM Unveils New Chip With 520 Qubits, Plans to Link Two for 1,000-Plus by 2027 — BigGo Finance

IBM on the 11th announced its next-generation quantum processor, the “IBM Quantum Nighthawk r3.” Designed to accurately execute 10,000 quantum operations on 520 programmable qubits, the company disclosed plans to connect two units in 2027 to build a single 1,040-qubit system. The move makes clear IBM’s strategy of simultaneously scaling up size while raising both the quality and speed of computation as it pursues the practical application of quantum computing.

The r3 simply scales up the high-speed computing architecture demonstrated by the current “Nighthawk r2.” The total number of physical qubits is 2,034. While maintaining the square-lattice connectivity inherited from the r2, it newly carries 10 inter-chip connection technologies called “L-couplers” that link processors to one another. At its core is a modular design philosophy in which multiple chips are linked and treated as a single computer.

IBM has already demonstrated the elemental technologies underpinning this…
