The simulation validates magic state cultivation, an approach that requires 90% fewer qubits than previous methods for fault-tolerant quantum computing.
NVIDIA announced a record-breaking quantum computing simulation on JUPITER, Europe’s first exascale supercomputer, allowing researchers to fully explore and validate magic state cultivation — a leading approach to fault-tolerant quantum computing that requires 90% fewer qubits than previous methods.
Running on a system of NVIDIA GH200 superchips at Jülich Supercomputing Centre, the 104-qubit simulation is the largest comprehensive simulation of a fault-tolerant quantum processor to date, modeling how a realistic quantum processor performs fault-tolerant computation at record scale.
Computing in the presence of such noise — known as fault-tolerant quantum computing — requires the use of magic states, a specific arrangement of qubits that is continually consumed during a fault-tolerant quantum computation.
Fault-tolerant quantum computers rely crucially on repeatedly producing magic states — meaning that any optimization in how they are made drastically reduces the difficulty of building a useful quantum computer.
