Quantinuum QUANTUM NEWS AND UPDATES

Quantum computing company Quantinuum made three more announcements at IEEE Quantum Week 2022. Announcements include another quantum volume record, a new method to make two-qubit gates with higher fidelity and greater efficiency, and a milestone achievement of more than a half-million downloads of its software.

1. Highlight 1: Shuttling ion pairs through intersections and negotiating 90 degree turns: It may not sound significant, but this research provides the capability to execute Quantinuum’s long term roadmap for future generations of H-series quantum computers. Ion trap researchers have been working on this problem for years. Prior to Quantinuum’s research, it was believed that the only way for paired ions to move through zones was to first separate the pair, then move them through junctions one at a time. That solution would have significantly increased processing time.
2. Highlight 2: Closing the gap on fault-tolerant quantum error correction: Fault tolerant quantum error correction will make it possible to build quantum computers with enough qubits to solve problems far beyond the reach of today’s supercomputers. Quantinuum researchers were able to construct a logical entangling circuit that had a higher fidelity than its physical counterpart.
