Next-Generation Semiconductor Quantum Computer to Debut at Osaka Expo

Innovative Quantum Technology Showcase

The upcoming Kansai-Osaka Expo will feature a full-scale mockup of a next-generation semiconductor quantum computer, with the actual prototype scheduled for completion next year. This exhibition will provide visitors with a realistic visualization of the device's dimensions alongside detailed specifications.

Advanced Quantum Architecture

The quantum computer utilizes a specialized "Exchange Only" control system, featuring 6 physical qubits and 2 logical qubits. The design accommodates both room temperature control and cryogenic CMOS operations at 4K, allowing for comprehensive performance evaluation.

The quantum chip itself operates in the 0.3-0.5K temperature range, with both the System-on-Chip (SoC) and standalone quantum chip configurations available for assessment.

Production-Ready Design

The system boasts two significant advantages that make it suitable for mass production:

• Compact chassis design
• Low power consumption requirements

Revolutionary Control Approach

Unlike conventional quantum computers that rely on microwave technology, this model implements a fully digital approach through PWM (Pulse Width Modulation) control of block pulses. The quantum operating system features custom algorithms specifically designed for the Exchange Only architecture.

This innovative approach significantly reduces resource requirements, with primarily DC wiring connections that minimize the need for coaxial cables or high-frequency components.

Experience Tomorrow's Computing Today

The exhibition represents an exceptional opportunity for researchers, industry professionals, and technology enthusiasts to witness firsthand the next evolution in quantum computing technology. Visitors interested in quantum computing development are encouraged to attend the expo to explore this groundbreaking technology.
