What exactly does quantum computing aim to solve that classical computing can't, and which industries are expected to be disrupted first?

Quantum computing targets three fundamental problem classes that scale exponentially beyond classical capabilities: simulation of quantum systems, integer factorization, and combinatorial optimization.

Simulation of quantum systems requires tracking exponentially many quantum states that classical memory cannot store. Drug-target binding simulations involve modeling molecular interactions at atomic scale where a 300-atom protein requires 2^300 quantum states—far exceeding all classical storage on Earth. Materials science applications like novel catalyst design and superconductor discovery face identical scaling challenges.

Integer factorization through Shor's algorithm can break RSA encryption in polynomial time versus classical computers requiring exponential time. A quantum computer with 4,000 logical qubits could factor 2048-bit RSA keys, threatening current cybersecurity infrastructure. Post-quantum cryptography development has become urgent across financial services and government sectors.

Combinatorial optimization problems like portfolio optimization, supply chain routing, and resource allocation grow exponentially with problem size. Classical algorithms require checking 2^n possible solutions, while quantum approximate optimization algorithms (QAOA) offer potential polynomial speedups for NP-hard problems.

Finance leads early adoption with JPMorgan's quantum risk pipeline on Amazon Braket and BMO's partnership with Xanadu for trading optimization. Pharmaceuticals follow closely—Pfizer collaborates with IBM on protein simulation while Amgen explores quantum molecular modeling. Logistics companies like DHL test quantum route optimization for international shipping networks.

Which companies are currently leading the quantum computing race in terms of real-world applications and technical milestones?

IBM dominates with 433-qubit Osprey processors and commercial Qiskit framework serving thousands of developers globally. Their quantum cloud platform processes over 3 billion quantum circuits annually across 200+ corporate and academic partners including ExxonMobil and Cleveland Clinic.
