Quantum Computing Market Milestone: Japan Launches 256-Qubit Superconducting Quantum Computer

The Quantum Computing Market reached US$ 650.1 million in 2022 and is expected to reach US$ 8,788.8 million by 2031, growing with a CAGR of 38.9% during the forecast period 2024-2031.

Japan has unveiled a 256-qubit superconducting quantum computer, jointly developed by RIKEN and Fujitsu. This machine is now one of the most powerful quantum computers globally, quadrupling the capacity of the previous 64-qubit system.

It features a scalable 3D architecture that groups qubits into 4-qubit unit cells, enhancing expansion capabilities.

The system fits into the same cooling infrastructure used for smaller machines, thanks to a compact high-density design.

Quantum computing is an advanced computing paradigm that leverages the principles of quantum mechanics, such as superposition and entanglement, to perform complex calculations at speeds far beyond the capabilities of classical computers. It uses quantum bits (qubits) instead of traditional binary bits, enabling simultaneous computation and exponential processing power, particularly valuable for solving problems in cryptography, material science, finance, and drug discovery.
