Quantum Complexity

Quantum complexity refers to how difficult it is to solve certain problems using quantum computers compared to classical ones. It measures the resources—like time or qubits—needed to find solutions, especially for problems that are very hard for traditional computers. Quantum computers leverage principles like superposition and entanglement, allowing them to process many possibilities simultaneously. This can make some problems, such as factoring large numbers or simulating molecules, much more efficient to solve. Understanding quantum complexity helps researchers identify which problems could benefit most from quantum computing, guiding future technological developments.
