Quantum computing is still in its development phase, but 2025 could be a crucial year for its advancement, according to a report published by Fujitsu experts Shintaro Sato, Stefan Walter, and Andreas Rohnfelder. The researchers anticipate significant progress in quantum error correction, specialized hardware, and software, enabling this technology to address complex challenges in areas such as materials simulation, quantum cryptography, and drug development.
Error Correction: The Key to Quantum Scalability
One of the biggest challenges in quantum computing is error correction. Unlike classical bits, qubits are extremely unstable and susceptible to errors due to decoherence and imperfections in computational processes. To tackle this issue, scientists have developed what are called quantum error correction codes (QECC), which are expected to make a significant leap in their evolution by 2025.
Among the most anticipated advancements in QECCs are:
- Optimization of surface codes: A reduction in the number of physical qubits needed to represent a logical qubit is expected, making large-scale quantum computation implementation more efficient.
- Development of low-density quantum parity codes (QLDPC): These will allow for greater error tolerance and may outperform surface codes in many cases.
- Hybrid coding: The combination of different types of correction codes to improve reliability and minimize computational cost.
Advances in this field could enable quantum computers to perform deeper calculations without being affected by accumulating errors, a fundamental step for their application in industrial and scientific scenarios.
Development of Ultra-Fast Decoders
One of the most innovative aspects that will shape the future of quantum computing is the emergence of high-speed decoders. These algorithms, combined with specialized hardware, will enable real-time error correction, preventing errors from propagating and affecting the accuracy of calculations.
The speed of error detection and correction is crucial, as any delay could compromise the integrity of the processed information. Fujitsu highlights that in 2025, there will be progress in integrating these decoders into quantum systems, enhancing their reliability and bringing them closer to broader commercial use.
New Practical Applications in Science and Technology
Advances in error correction and system architecture will open new doors for their application in strategic sectors. Among the areas most benefited by quantum computing are:
- Development of new materials: Quantum simulation will allow for the design of materials with unprecedented properties, ranging from superconductors to ultra-resistant materials.
- Pharmaceutical industry and biotechnology: Quantum computers will be able to model complex molecular interactions, facilitating the development of more effective and personalized medications.
- Quantum cryptography: Advances are expected in creating quantum encryption systems that will enhance the security of global communications.
According to Fujitsu experts, these advancements will mark a turning point in quantum computing, allowing for the tangible implementation of quantum technology in industry in the coming years.
Fujitsu’s Commitment to Quantum Computing
The Japanese multinational has already developed its own quantum computing system inspired by Quantum Annealing, a technique that efficiently solves optimization problems. With this, Fujitsu is promoting quantum applications in key sectors such as automotive, logistics, and finance.
According to Shintaro Sato, Senior Vice President and leader of the Quantum Laboratory at Fujitsu, the goal is to continue advancing towards hybrid systems that combine quantum computing with artificial intelligence and classical supercomputing to maximize data processing efficiency.
“Quantum computing is in a stage of accelerated growth. Thanks to advancements in error correction and hardware architecture, we are getting closer to overcoming the barriers that have limited its application in the real world,” Sato states.
2025 is shaping up to be a decisive year for the evolution of quantum computing, with advancements that could accelerate the arrival of a new technological era.
