In 2019, Google announced quantum supremacy: their Sycamore processor solved a problem in 200 seconds that would have taken a supercomputer 10,000 years. This was the moment when quantum computing ceased to be science fiction and became a new stage in technological evolution.<\/p>\n
A classical bit is either 0 or 1. A quantum bit (qubit) is a superposition: it can be 0, 1, or both simultaneously. And entanglement allows qubits to be linked so that the state of one instantly influences another \u2013 even over a distance. This violates classical logic but follows the laws of quantum physics.<\/p>\n
Why is this important? Because some problems cannot be solved classically. For example, modeling molecules for drugs, optimizing logistics, breaking encryption. A quantum computer is not “faster.” It thinks differently.<\/p>\n
Today, qubits are created from superconducting circuits (Google, IBM), ions (IonQ), and photons (Xanadu). But they are fragile: any interaction with the outside world destroys their state. Therefore, they are cooled to -273\u00b0C\u2014closer to absolute zero than space.<\/p>\n
IBM plans to create a 1000-qubit processor by 2026. But quantity isn’t everything. Quality (low error rate) is key. For now, quantum computers are needed for hybrid solutions: classical and quantum.<\/p>\n

There are already practical applications. In 2023, Roche used quantum computing to model a protein associated with Alzheimer’s disease. Volkswagen optimized taxi routes in Beijing. This is just the beginning.<\/p>\n
But a quantum computer won’t replace your laptop. It’s not for social media or movies. It’s for specific tasks that require colossal computing power.<\/p>\n
The main threat is cryptography. Modern ciphers (RSA) are based on the difficulty of factoring numbers. Shor’s quantum algorithm can crack them in hours. That’s why post-quantum ciphers are already being developed.<\/p>\n
Quantum physics has always seemed abstract. But now it’s in chips. In laboratories. In the future.<\/p>\n
In conclusion, a quantum computer is more than just a technology. It’s a new perspective on reality. Where not everything is black and white. Where it’s possible to be both at once. And where the future has already begun.<\/p>\n","protected":false},"excerpt":{"rendered":"
