Quantum-selected configuration interaction with time-evolved state
Mathias Mikkelsen, Yuya O. Nakagawa
Quantum-selected configuration interaction (QSCI) utilizes an input quantum state on a quantum device to select important bases (electron configurations in quantum chemistry) that…
Quantum many-body simulation of finite-temperature systems with sampling a series expansion of a quantum imaginary-time evolution
Norifumi Matsumoto, Shoichiro Tsutsui, Yuya O. Nakagawa +5
Simulating thermal-equilibrium properties at finite temperature is crucial for studying quantum many-body systems. Quantum computers are expected to enable us to simulate large sys…
Subspace-Based Local Compilation of Variational Quantum Circuits for Large-Scale Quantum Many-Body Simulation
Shota Kanasugi, Yuichiro Hidaka, Yuya O. Nakagawa +5
Simulation of quantum many-body systems is a promising application of quantum computers. However, implementing the time-evolution operator as a quantum circuit efficiently on near-…
Qubit frugal entanglement determination with the deep multi-scale entanglement renormalization ansatz
Kushagra Garg, Zeeshan Ahmed, Andreas Thomasen
We study the deep multi-scale entanglement renormalization ansatz (DMERA) on quantum hardware and the causal cone of a subset of the qubits which make up the ansatz. This causal co…
Bias-preserving computation with the bit-flip code
Shoichiro Tsutsui, Keita Kanno
We explore the feasibility of fault-tolerant quantum computation using the bit-flip repetition code in a biased noise channel where only the bit-flip error can occur. While several…
Minimizing readout-induced noise for early fault-tolerant quantum computers
Yunzhe Zheng, Keita Kanno
Quantum error correcting code can diagnose potential errors and correct them based on measured outcomes by leveraging syndrome measurement. However, mid-circuit measurement has bee…
Quantum-Selected Configuration Interaction: classical diagonalization of Hamiltonians in subspaces selected by quantum computers
Keita Kanno, Masaya Kohda, Ryosuke Imai +4
We propose quantum-selected configuration interaction (QSCI), a class of hybrid quantum-classical algorithms for calculating the ground- and excited-state energies of many-electron…
