Google’s quantum computer instantly makes calculations that take rivals 47 years

Google has developed a quantum computer that can perform calculations 241 million times faster than its previous machine, which achieved “quantum supremacy” in 2019. The new device has 70 qubits, compared to 53 qubits in the previous model, making it beyond the capabilities of existing classical supercomputers. The breakthrough has potential applications in solving complex problems related to climate change and medical research. However, there are concerns about the threat quantum computers pose to encryption systems, making it a national security priority. Critics argue that the algorithm used in the demonstration lacks real-world practical applications.
