QUANTUM COMPUTING

1. Industry Overview & Evolution

Historical Trajectory

Early research in quantum physics during the 1980s prompted speculation that quantum mechanical phenomena such as superposition and entanglement could accelerate computation. In 1994 Peter Shor devised a quantum algorithm capable of factoring large integers exponentially faster than classical algorithms, and Lov Grover demonstrated a quadratic-speed search algorithm. This theoretical breakthrough motivated laboratories to seek practical quantum bits (qubits). During the late 1990s and 2000s, experimental qubits were demonstrated in trapped ions and superconducting circuits. IBM's team demonstrated a five-qubit superconducting quantum processor in 2012 and in 2016 made a 5-qubit device available on the cloud, catalyzing public experimentation.

In 2019 Google announced that its 54-qubit Sycamore processor performed a random-circuit sampling experiment in about 200 seconds that would take a classical supercomputer days. The event, widely labelled "quantum supremacy," demonstrated that quantum hardware could perform a specific task faster than known classical algorithms. IBM, which had launched the IBM Q cloud in 2016, followed with successive superconducting processors: Eagle (127 qubits, 2021) and Osprey (433 qubits, 2022). Other platforms matured: D-Wave commercialized quantum annealing processors with over 5,000 qubits; IonQ and Quantinuum advanced trapped-ion systems; and photonic companies such as Xanadu reported Gaussian boson sampling experiments demonstrating the capability of 216 squeezed optical modes. Neutral-atom systems emerged, with QuEra launching a 256-qubit device via Amazon Braket and Pasqal trapping more than 1,110 atoms in a single shot. By 2025 the technological landscape contained multiple architectures—superconducting, trapped-ion, photonic and neutral atoms—each with unique advantages and scaling challenges.

Current Landscape

Today's quantum computing industry is at an early commercialization stage. Hardware vendors sell systems and provide access through cloud platforms, while software companies build control, error-correction and application stacks. According to Grand View Research, the global quantum computing market in 2024 was valued at US$1.42 billion; SRI International estimates that total industry revenue from quantum computing and sensing reached US$1.07 billion in 2024. The market remains dominated by hardware systems (64% share in 2024) because users prefer on-premises control for sensitive data.

Technology Platforms

Future Outlook (Next 5–10 Years)

Over the coming decade the industry aims to transition from noisy intermediate-scale quantum (NISQ) devices to fault-tolerant quantum computers with millions of physical qubits. IBM plans a 1,000-qubit processor (Condor) around 2025–2026 and has set an aspirational goal of reaching a million qubits by the end of the decade. PsiQuantum seeks a million-qubit photonic computer and is building a dedicated cryogenic plant in Australia with ~US$620M of government support. Pasqal intends to scale neutral-atom processors to 10,000 qubits by 2026–2027, while Microsoft unveiled a Majorana-based topological qubit architecture and aims to integrate one million qubits on a single chip, pursuing fault tolerance and digital control.

As qubit counts grow, error-corrected logical qubits should enable practical algorithms for molecular simulation, combinatorial optimization, secure communication and cryptanalysis. Integration with high-performance computing (HPC) and artificial intelligence (AI) is expected to create hybrid quantum-classical workflows. MarketsandMarkets projects IBM's market share could rise from 25% in 2020 to 35% by 2025, implying industry consolidation. Overall, the next decade is likely to see intensifying competition, significant venture and public funding, and early real-world applications as error-corrected machines become available.
