China unveils world’s first superfast quantum memory, paving way for practical computing

Chinese scientists have created the world’s first superfast memory for quantum computers, solving a critical data-reading bottleneck and paving the way for big-data challenges such as drug discovery and detecting fraudulent financial activities. Quantum computers are expected to solve complex problems at speeds unattainable by traditional computers, and they need an efficient way to access classical data. Without a high-speed data interface, even the fastest quantum machine is slowed down when...
