- State-dependent error bound for digital quantum simulation of driven
systems-
Free pre-print version: Loading...
Authors: Takuya Hatomura
Abstract: Author(s): Takuya Hatomura
Digital quantum simulation is a promising application of quantum computers where quantum dynamics is simulated by using quantum gate operations. Many techniques for decomposing a time-evolution operator of quantum dynamics into simulatable quantum gate operations have been proposed, whereas these me…

Authors: Mahaveer Prasad; Hari Kumar Yadalam, Camille Aron, Manas Kulkarni
Abstract: Author(s): Mahaveer Prasad, Hari Kumar Yadalam, Camille Aron, and Manas Kulkarni
We explore the connections between dissipative quantum phase transitions and non-Hermitian random matrix theory. For this, we work in the framework of the dissipative Dicke model which is archetypal of symmetry-breaking phase transitions in open quantum systems. We establish that the Liouvillian des…

Abstract: Author(s): Louisiane Devaud, Bernhard Rauer, Matthias Kühmayer, Jakob Melchard, Mickaël Mounaix, Stefan Rotter, and Sylvain Gigan
The complex temporal behavior of an ultrashort pulse of light propagating through a multiple scattering medium can be characterized experimentally through a time-gated transmission matrix. Using a spatial light modulator, we demonstrate here that injecting singular vectors of this matrix allows us t…

Abstract: Author(s): Ángel L. Corps and Armando Relaño
We show that excited-state quantum phase transitions (ESQPTs) in a system in which the parity symmetry is broken can be used to engineer an energy cat state—a Schrödinger cat state involving a quantum superposition of both different positions and energies. By means of a generalization of the Rabi mo…

Gaussian boson sampling is a candidate model for demonstrating quantum computational advantage in photonic systems. Here, the authors narrow down the range of possible architectures for such a demonstration, by introducing a classical algorithm that can simulate optical systems with shallow-depth circuits and local gates in polynomial time.

The variational quantum eigensolver (VQE), which has attracted attention as a promising application of noisy intermediate-scale quantum devices, finds a ground state of a given Hamiltonian by variationally optimizing the parameters of quantum circuits called Ansätze. Since the difficulty of the opti…

Graph states are a central resource in measurement-based quantum information processing. In the photonic qubit architecture based on Gottesman-Kitaev-Preskill (GKP) encoding, the generation of high-fidelity graph states composed of realistic, finite-energy approximate GKP-encoded qubits thus constit…

In order to better characterize the performance of trapped ion systems and ease the experimental difficulties of addressing individual ions, the authors apply carefully-timed pulse sequences to ion chains up to 51 ions long. These techniques allow them to generate entanglement between all neighboring ion pairs and to quantify and mitigate sources of decoherence in the chains.

Abstract: Author(s): Donghui Yang, Zheng-Da Hu, Shuailing Wang, and Yun Zhu
Photonic orbital angular momentum (OAM) carrying orthogonal modes exhibits fascinating nature for information encoding. Here we focus on the propagation of OAM states in random media to investigate the turbulence-induced OAM degradation. We utilize the quadratic approximation of the phase structure …
