Quantum Computers: How Physics Is Redefining Technology

Quantum computers use qubits, which can exist in multiple states simultaneously thanks to superposition.
Unlike classical bits, qubits enable quantum computers to process vast amounts of data in parallel.
Entanglement allows qubits to be interconnected, creating correlations that classical computers cannot replicate.
Quantum computers could solve problems in seconds that would take classical computers millennia.
Applications include cryptography, drug discovery, optimization, and simulating quantum systems.
Noise and decoherence remain major challenges, requiring error-correcting codes and ultra-cold environments.
Quantum supremacy was first claimed in 2019, marking the ability of a quantum computer to outperform classical ones on a specific task.
Leading quantum technologies include superconducting circuits, trapped ions, and photonic qubits.
Quantum computers are poised to revolutionize AI, materials science, and secure communications.
Understanding and harnessing quantum physics for computing could redefine technology and our approach to complex problems.
