Quantum computers are in early stages but hold immense potential. They use qubits that can be 0 and 1 at the same time. This allows for solving complex problems that are impossible for classical computers. Challenges include keeping qubits stable. If these challenges are overcome, quantum computing could revolutionize many industries.

Inspired by Richard Feynman, Quantum computers could solve problems impossible for regular computers. Google claims to have achieved "quantum supremacy" with their machine. IBM disputes the claim, saying a classical computer could do it too. Regardless, Google's achievement is a big step towards real-world quantum computing.

This article discusses challenges and potential breakthroughs in quantum computing. The main obstacle is qubit fragility, which causes errors. Researchers are looking into ways to reduce noise and improve coherence time. Other promising areas include hybrid qubit devices, qutrits, and topological superconductivity.

This article explores the development of quantum computers. While some companies offer limited quantum computing abilities, a general-purpose machine is still being pursued. Many researchers are optimistic about potential breakthroughs due to frequent advancements in algorithms, qubits, and theories. There are challenges, such as qubit fragility, but also promising areas, like Majorana fermions and two-qubit gates. The practical application is expected to revolutionize various scientific fields. The exact arrival time of a universal quantum computer remains unclear.
