Matrix Product Evolution: A Method for Simulating Quantum Circuits Using Tensor Networks
Haruyuki Kawabe, Minoru Nagai, Tsuyoshi Okubo +1
Classical simulation of quantum circuits is an essential tool in quantum information science, but its applicability is constrained by the exponential growth of the Hilbert space an…
Simplification of tensor updates toward performance-complexity balanced quantum computer simulation
Koichi Yanagisawa, Tsuyoshi Okubo, Shota Koshikawa +3
Matrix Product States (MPS) provide a powerful framework for simulating quantum circuits. In practical simulations, tensor updates are typically performed in the canonical form (CF…
Efficient tomography of microwave photonic cluster states
Yoshiki Sunada, Shingo Kono, Jesper Ilves +6
Entanglement among a large number of qubits is a crucial resource for many quantum algorithms. Such many-body states have been efficiently generated by entangling a chain of itiner…
Tensor train representations of Greeks for Fourier-based pricing of multi-asset options
Rihito Sakurai, Koichi Miyamoto, Tsuyoshi Okubo
Efficient computation of Greeks for multi-asset options remains a key challenge in quantitative finance. While Monte Carlo (MC) simulation is widely used, it suffers from the large…
Embedding of Tree Tensor Networks into Shallow Quantum Circuits
Shota Sugawara, Kazuki Inomata, Tsuyoshi Okubo +1
Variational Quantum Algorithms (VQAs) are being highlighted as key quantum algorithms for demonstrating quantum advantage on Noisy Intermediate-Scale Quantum (NISQ) devices, which…
