Quantum computing represents a revolutionary new model of computing that harnesses the power of quantum mechanics to solve complex problems beyond the reach of classical computers. The strange properties of quantum physics, such as superposition and entanglement, allow quantum computers to process information differently. We are now at the cusp of the quantum computing revolution as leading technology companies race to build practical quantum computers.

**Understanding Quantum Technology and Its Impact**

Quantum computers utilize quantum bits or “qubits” as their basic unit of information. Unlike classical binary bits that can only be in a state of 0 or 1, qubits can exist in a superposition of both states at once. This allows quantum computers to perform calculations on many different inputs simultaneously. The exponential scale-up in processing power promises to transform fields from drug design to artificial intelligence.

**The Emergence of Quantum Computing Industry**

While quantum computing research began in the 1980s, the past decade has seen rapid commercialization efforts and an emerging quantum industry. Hardware startups like IonQ and Rigetti Computing are building next-gen quantum processors using technologies like trapped ions and superconducting qubits.
