State of the Art Quantum Chemistry in 2022

Quantum chemistry is very hard. The best quantum computing chemistry seems to be at the level of 12 qubits / 12 atoms. Supercomputer simulations can handle 20 qubits and 20 atoms simulation. There are early papers that suggest classical supercomputers can get to 100 atoms and 1000 qubit for some types of simulation. Quantum computers …

IBMs 433 Qubit Quantum Processor and Beyond

IBM has a 433 qubit quantum processor called Osprey and has a roadmap for 4000 qubits in 2025 and 100,000 qubits by 2030. These are more powerful qubits than the 5000+ adiabatic qubits from DWave Systems. Most other quantum computer companies are at about 50-100 qubits. The number of usable error-mitigated qubits is being improved. …
