Circuit growth and subspace read-out in quantum-selected configuration interaction: Separating the Hartree-Fock determinant
Ayaka Fujimoto, Norifumi Matsumoto, Shota Kanasugi +2
Predicting many molecular properties requires accurate ground-state energies of molecular Hamiltonians. Quantum-selected configuration interaction (QSCI) obtains such energies by m…
Enabling Chemically Accurate Quantum Phase Estimation in the Early Fault-Tolerant Regime
Shota Kanasugi, Riki Toshio, Kazunori Maruyama +1
Quantum simulation of molecular electronic structure is one of the most promising applications of quantum computing. However, achieving chemically accurate predictions for strongly…
STAR-Magic Mutation: Even More Efficient Analog Rotation Gates for Early Fault-Tolerant Quantum Computer
Riki Toshio, Shota Kanasugi, Jun Fujisaki +3
We introduce STAR-magic mutation, an efficient protocol for implementing logical rotation gates on early fault-tolerant quantum computers. This protocol judiciously combines two of…
