Japanese Supercomputer Fugaku
The world’s first hybrid quantum supercomputer was officially in operation in Japan.
The Quantum Computer Reimei was successfully integrated into the Fugakuthe sixth fastest supercomputer in the world.
The hybrid platform is designed to make calculations that classic supercomputers can take much longer to process.
The machine, which is installed at the Riken Scientific Institute, near Tokyo, will be mainly used for research in physics and chemistry, explained the creators of Reimei, in a joint statement, quoted by.
The creators stated that they chose Fugaku for integration because it has a unique architecture that physically moves the QBits. This “ion transport” process allows QBits to be moved in a circuit as necessary, allowing more complex algorithms.
Reimei is a great progest
Unlike most quantum computers that use superconducting quibits, Reimei uses trapped ions.
This implies the isolation of loaded atomsor ions, in an electromagnetic field – known as ion trap – and the use of lasers to accurately control their quantum state.
This technology allows scientists to manipulate ions so that they can be used as quibits that store and process quantum information.
However, the imprisoned ionic quibits boost more connections between quibits and longer coherence times; While superconducting quibits have faster door connections and are easier to make on chips.
Error Correction System
Os quibits are inherently “noisy”Note Live Science, so to effectively increase the scale of quantum computers, scientists are developing error correction techniques to increase the loyalty of quibits.
At Reimei, physical ionic quibits were grouped to create “logical quibits” – that is, a set of physical quibits that store the same information in various locations.
Logic quibits are a fundamental way to achieve the desired reduction of QBIT errors, because the distribution of information in different locations distributes the failure points, which means that A QUBIT failure does not interrupt an ongoing calculation.
Although Reimei-Fugaku is the first integrated and fully operational hybrid system, other companies have tested systems of this type. In June 2024, IQM was part of a Quantum Processor of 20 QBits (such as Reimei) at the Supermuc-NG supercomputer in Garching, Germany.
