Classification and reconstruction of optical quantum states with deep neural networks
Shahnawaz Ahmed, Carlos Sánchez Muñoz, Franco Nori +1
We apply deep-neural-network-based techniques to quantum state classification and reconstruction. We demonstrate high classification accuracies and reconstruction fidelities, even…
Fast binomial-code holonomic quantum computation with ultrastrong light-matter coupling
Ye-Hong Chen, Wei Qin, Roberto Stassi +2
We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. I…
Comparative Study of Sampling-Based Simulation Costs of Noisy Quantum Circuits
Shigeo Hakkaku, Keisuke Fujii
Noise in quantum operations often negates the advantage of quantum computation. However, most classical simulations of quantum computers calculate the ideal probability amplitudes…
Spectroscopic observation of the crossover from a classical Duffing oscillator to a Kerr parametric oscillator
T. Yamaji, S. Kagami, A. Yamaguchi +6
We study microwave response of a Josephson parametric oscillator consisting of a superconducting transmission-line resonator with an embedded dc-SQUID. The dc-SQUID allows to contr…
Quantum-inspired search method for low-energy states of classical Ising Hamiltonians
Hiroshi Ueda, Yuichi Otsuka, Seiji Yunoki
We develop a quantum-inspired numerical procedure for searching low-energy states of a classical Hamiltonian composed of two-body fully-connected random Ising interactions and a ra…
Effect of on-site Coulomb repulsion on ferromagnetic fluctuations in heavily over-doped cuprates
Shingo Teranishi, Kazutaka Nishiguchi, Seiji Yunoki +1
We theoretically study ferromagnetic (FM) fluctuations that are experimentally observed in the heavily overdoped region of cuprate superconductors. To explore the origin of FM fluc…
Unraveling the topology of dissipative quantum systems
Clemens Gneiting, Akshay Koottandavida, Alexander V. Rozhkov +1
We discuss topology in dissipative quantum systems from the perspective of quantum trajectories. The latter emerge in the unraveling of Markovian quantum master equations and/or in…
One-hundred step measurement-based quantum computation multiplexed in the time domain with 25 MHz clock frequency
Warit Asavanant, Baramee Charoensombutamon, Shota Yokoyama +8
Among various approaches toward quantum computation, measurement-based quantum computation (MBQC) multiplexed in time domain is currently a promising method for addressing the need…
Magnon-exciton proximity coupling at a van der Waals heterointerface
Arnaud Gloppe, Masaru Onga, Ryusuke Hisatomi +4
Spin and photonic systems are at the heart of modern information devices and emerging quantum technologies. An interplay between electron-hole pairs (excitons) in semiconductors an…
Quantum steering as a witness of quantum scrambling
Jhen-Dong Lin, Wei-Yu Lin, Huan-Yu Ku +3
Quantum information scrambling describes the delocalization of local information to global information in the form of entanglement throughout all possible degrees of freedom. A nat…
Jumptime unraveling of Markovian open quantum systems
Clemens Gneiting, Alexander V. Rozhkov, Franco Nori
We introduce jumptime unraveling as a distinct description of open quantum systems. As our starting point, we consider quantum jump trajectories, which emerge, physically, from con…
