Microsoft unveils breakthrough quantum-computing chip Majorana 1, aiming to scale up to 1 million qubits

From Nasdaq: 2025-02-20 07:35:00

Microsoft has unveiled a quantum-computing chip, Majorana 1, that harnesses Majorana particles for encoding quantum information. This breakthrough comes after nearly 20 years of research. The chip currently contains eight qubits, with plans to scale up to 1 million for real-world problem solving.

Error correction is a major challenge in quantum computing, but Majorana particles used by Microsoft are more stable and less error-prone. Despite some errors, Microsoft is working on reducing and correcting them to scale up the chip successfully.

Microsoft aims to build fault-tolerant quantum computers based on Majorana particles in years. However, challenges remain, including full error correction, scaling to a useful qubit count, and competition from other tech giants. The potential economic value of quantum computing is enormous, but success is still years away.

Microsoft is focusing on quantum chips for cloud data centers, potentially creating a new line of business. While considerable challenges lie ahead, the company’s innovative Majorana 1 chip could accelerate progress towards useful quantum computing. The competition includes Alphabet, IBM, and other tech companies.
