What It Is

Quantum computers use qubits, which can represent multiple states simultaneously, rather than the binary bits of classical computing. For a narrow set of problems this offers a theoretical advantage no classical machine can match.

The field remains firmly in the research and early commercialisation phase, with error correction the central unsolved engineering problem.

Where Capital Is Going

Hardware development across competing qubit architectures
Error correction and fault tolerance research
Quantum software, compilers, and algorithm development
Post-quantum cryptography, preparing for future decryption capability
Cloud access platforms providing shared machine time

Key Applications

Molecular simulation for drug and materials discovery
Optimisation problems in logistics and finance
Cryptography and its eventual disruption
Complex systems modelling

Challenges

Qubit stability and error rates remain the fundamental barrier
Extreme operating conditions, including near-absolute-zero cooling
Very few problems where advantage over classical computing is proven
Long horizon to commercial return, testing investor patience
Scarce specialist talent
