THE NEXT BIG QUANTUM COMPUTER HAS ARRIVED

Summary from the TLDR newsletter

Quantinuum's Helios machine contains 98 physical qubits, and from those, it can deliver 48 logical error-corrected qubits. The 2:1 ratio is unique - other machines require anything from dozens to hundreds of physical qubits to create one logical qubit. Quantinuum expects to create a large-scale fault-tolerant machine by 2029 with its upcoming Apollo machine, which will have thousands of physical qubits and hundreds of logical ones. Its customers include JPMorgan Chase, which has been using Helios in private preview to run complex algorithms.
