Spin-One Secondary Pairing in Two-Flavor Color Superconductivity: Spinful Relativistic Superfluidity and Anomaly Matching
Naoki Yamamoto
We study secondary pairing in the two-flavor color-superconducting (2SC) phase, where the residual ungapped quarks form a same-chirality condensate driven by an attractiv…
Quantum Metric and Nonlinear Hall Effect of Photons
Keidai Akiba, Naoki Yamamoto
Using the path-integral formalism, we show that photons possess a nontrivial quantum metric in momentum space. We derive the semiclassical action and equations of motion by taking…
Generating quantum entanglement between macroscopic objects with continuous measurement and feedback control
Daisuke Miki, Nobuyuki Matsumoto, Akira Matsumura +4
This study is aimed at investigating the feasibility of generating quantum entanglement between macroscopic mechanical mirrors in optomechanical systems while under continuous meas…
Jarzynski-like Equality of Nonequilibrium Information Production Based on Quantum Cross Entropy
Akira Sone, Naoki Yamamoto, Tharon Holdsworth +1
The two-time measurement scheme is well studied in the context of quantum fluctuation theorem. However, it becomes infeasible when the random variable determined by a single measur…
Overfitting in quantum machine learning and entangling dropout
Masahiro Kobayashi, Kouhei Nakaji, Naoki Yamamoto
The ultimate goal in machine learning is to construct a model function that has a generalization capability for unseen dataset, based on given training dataset. If the model functi…
Numerical analysis of quantum circuits for state preparation and unitary operator synthesis
Sahel Ashhab, Naoki Yamamoto, Fumiki Yoshihara +1
We perform optimal-control-theory calculations to determine the minimum number of two-qubit CNOT gates needed to perform quantum state preparation and unitary operator synthesis fo…
