Impact of Measurement Noise on Escaping Saddles in Variational Quantum Algorithms

Eriko Kaminishi, Takashi Mori, Michihiko Sugawara +1

Stochastic gradient descent (SGD) is a frequently used optimization technique in classical machine learning and Variational Quantum Eigensolver (VQE). For the implementation of VQE…

Noise Robustness of Quantum Relaxation for Combinatorial Optimization

Kentaro Tamura, Yohichi Suzuki, Rudy Raymond +5

QRAO (Quantum Random Access Optimization) is a relaxation algorithm that reduces the number of qubits required to solve a problem by encoding multiple variables per qubit using QRA…

Digital quantum simulator for the time-dependent Dirac equation using discrete-time quantum walks

Shigetora Miyashita, Takahiko Satoh, Michihiko Sugawara +5

We introduce a quantum algorithm for simulating the time-dependent Dirac equation in 3+1 dimensions using discrete-time quantum walks. Thus far, promising quantum algorithms have b…
