A quantum computing architecture to accelerate the early practical application of quantum computers

The new STAR Architecture, version 3, brings the practical calculation of complex molecular systems much closer to reality.
For calculations involving ruthenium (Ru) catalysts, combining it with molecular optimization dramatically reduces the number of required qubits from approximately 2 million with conventional FTQC to about 20,000, and shortens the estimated computation time from around 5,000 days to roughly 5 days.
