The engineers in Japan have turned on the first hybrid quantum supercomputer in the world.
The 20 -QUIT quantum computer, called Reimi, has been integrated into Fugaku, the The sixth supercomputer in the world. The hybrid platform will work to address the calculations that classic supercomputer can take much longer to process.
The machine, which is located in the Riken Scientific Institute in Saitama, near Tokyo, will be used mainly for physics and chemistry investigation, said representatives of Quantinuum, the manufacturers of Remiti, and Riken in a joint statement.
Quantum computers could someday overcome classic computers, with the potential to complete the calculations in minutes or seconds that would otherwise take the most powerful machines today millions of years. However, until quantum computers are large enough, scientists say that Integrating their capabilities into supercomputers It can be a stopgap.
Unlike most quantum computers that use superconduction QubitsESIMEI USA Dear ions of trapped ions. This implies isolating loaded atoms or ions, in an electromagnetic field, known as a ion trap – And use lasers to accurately control your quantum status.

This allows scientists to manipulate ions so that they can be used as qubits that store and process quantum information. Cattle ions ions foster more connections between the qubits and the longest coherence times, while superconductor qubits have faster door connections and are easier to manufacture in chips.
Riken’s representatives said they chose Quintinuum quantum computer for integration because it has a unique architecture that physically moves the qubits. This “”ion transfer“It allows the qubits to move around a circuit as necessary, which allows more complex algorithms.
Error correction system
Qubits are inherently “noisy”, so to effectively expand quantum computers, scientists are developing errors correction techniques to increase the fidelity of qubits.
In Reimii, physical ion ions have been grouped to create “logical qubits”, which means a set of physical qubits that store the same information in several places. Logical qubits are a key route to achieve a desired reduction in Qbit errors, because the distribution of information in different places extends the failure points, which means that a Qbito failure does not interrupt a continuous calculation.
Quintinuum previously achieved an advance when creating a logical qbit with a Error rate 800 times lower than physical qubitswhich integrated into its quantum computing processors.
While Hi-Fugaku is the first integrated and integrated hybrid system, other companies have previously tested such systems. In June 2024, IQM made up a 20 -QUIT quantum processor in the Supercomputadora Supermuc-Ng In Garching, Germany.
However, that system is still in the trial phase, without confirmed public date when it becomes completely operational. In October, IQM representatives announced that the company would integrate a 54 -QUIT system into the supercomputer in the second half of 2025 followed by a 150 -QUIT chip in 2026.
