100+ qubit NISQ devices are used in chemistry simulations.

Quantum computers have the potential to revolutionise chemistry and materials science by directly simulating molecular quantum behaviour. Current research shows quantum chemistry simulations at the 200-qubit scale are achievable with accelerated computing. By 2027, NISQ devices above 100 qubits are expected to be used in chemistry simulations.

Although these devices are noisy and lack error correction, they may offer advantages over classical computers for specific problems such as molecular energy calculations and material properties. IBM and other vendors' quantum roadmaps confirm the rapid growth in qubit counts.
