With this in mind, which companies have demonstrated steady quantum computing progress? 1. Honeywell International Inc. Although not typically perceived as a quantum computing company, Honeywell has two major advantages. First, as long as the dollar maintains its global reserve currency status, Honeywell will continue to serve the military industrial complex with its aerospace systems, alongside land, naval, satellite and autonomous systems. Honeywell's Aerospace Technologies (AT) division represented aroun ...

Core Insights - Rigetti Computing has been selected to participate in DARPA's Quantum Benchmarking Initiative (QBI) to assess the feasibility of achieving utility-scale quantum computing by 2033 [1][4] - The company aims to develop a Utility-Scale Quantum Computer (USQC) using its proprietary multi-chip architecture and scalable quantum error correction (QEC) codes, in collaboration with Riverlane [2][3] Group 1: DARPA QBI Participation - The QBI will evaluate quantum computing concepts through a multi-stage approach, with Rigetti advancing to Stage A, which includes a 6-month performance period and potential funding of up to $1 million [1] - The initiative's goal is to determine if any quantum computing approach can achieve utility-scale operation by 2033 [1] Group 2: Technology and Collaboration - Rigetti's USQC concept will utilize Quantum Low Density Parity Check (qLDPC) codes, which are more efficient than traditional surface codes, allowing for better scalability and reduced physical qubit overhead [3] - Riverlane, a partner specializing in QEC technology, will assist in refining and validating Rigetti's USQC concept [2] Group 3: Company Expertise and Roadmap - Rigetti has spent a decade developing intellectual property and expertise in quantum computing, positioning itself to deliver on the QBI program [4] - The company has made significant advancements in superconducting qubit technology, including a novel chip fabrication technique called Alternating Bias Assisted Annealing (ABAA) [4][5] - Rigetti's current 84-qubit Ankaa-3 system demonstrates a 99.0% ISWAP gate fidelity, with plans to scale to over 100 qubits while reducing error rates by 50% [5]
