Fixing Divergence in Carleman Linearization via Analytical Continuation
Mingshuo Zhu, Hayato Higuchi, Hokuto Iwakiri +4
Nonlinear differential equations play a crucial role in modeling a wide range of phenomena, yet their solutions remain notoriously difficult to obtain. With the rapid development o…
Fast-forwardability of Qubit-mapped Fermion models based on Cartan decomposition
Yuichiro Hidaka, Shoichiro Tsutsui, Shota Kanasugi +3
We study the Hamiltonian algebra of qubit-mapped interacting fermion models and their fast-forwardability. We prove that the dimension of the Hamiltonian algebra of the fermion mod…
Quantum expectation value estimation by doubling the number of qubits
Hiroshi Yano, Masaya Kohda, Shoichiro Tsutsui +4
Expectation value estimation is ubiquitous in quantum algorithms. The expectation value of a Hamiltonian, which is essential in various practical applications, is often estimated b…
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-…
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…
