      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…

      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…

      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.

      Frame synchronization is a crucial step in quantum key distribution (QKD) and a prerequisite for secure key distillation. Due to the extremely low signal-to-noise ratio (SNR) and fast phase drift in the continuous-variable QKD system, efficient frame synchronization is highly demanded. In this paper…

      Quantum process tomography (QPT) is a powerful tool to characterize quantum operations, but it requires considerable resources, making it impractical for more than two-qubit systems. This work proposes an alternative approach that requires significantly fewer resources for unitary process characteri…

      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.

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): Sareh Shahidani and Morteza Rafiee
      In this paper, we explore the Wigner entropy production rate in the stationary state of a two-mode Gaussian system. The interacting modes dissipate into different local thermal baths. Also, one of the bosonic modes evolves into the squeezed-thermal state because of the parametric amplification proce…

      Abstract: Author(s): Adam Sawicki, Lorenzo Mattioli, and Zoltán Zimborás
      We establish a relationship between the notion of universal quantum gates and the notion of unitary $t$-designs. We show that a set of qudit gates $\mathcal{S}⊂U(d)$ is universal if and only if $\mathcal{S}$ forms a $δ$-approximate $t(d)$-design, where $δ<1, t(2)=6$, and $t(d)=4$ for $d≥3$. Moreo…

      Abstract: Author(s): Weidong Li, Shuyuan Wu, Augusto Smerzi, and Luca Pezzè
      Improving the clock stability is of fundamental importance for the development of quantum-enhanced metrology. One of the main limitations arises from the randomly fluctuating local oscillator (LO) frequency, which introduces “phase slips” for long interrogation times and hence the failure of the fre…

      Abstract: Author(s): Bao Wang, Xiao Jia, Xiao-Hu Lu, and Hao Xiong
      Nonlinear magnonics based on the coupling of magnons and optical photons has become a crucial topic in the quantum magnonic field. Here, we demonstrate the magnon laser, the analog of the optical laser in magnonics, in a parity-time ($\mathcal{PT}$) symmetric cavity optomagnonical system involving a…

      In this work, we investigate the non-Markovian (NM) dynamical evolution of a three-level atom coupled to a semi-infinite one-dimensional photonic waveguide and driven by a classical driving field. The single-end of waveguide behaves as a perfect mirror while light can pass through the opposite end w…

      Many molecular, quantum-dot, and optomechanical nanocavity-QED systems demonstrate strong nonlinear interactions between electrons, photons, and phonon (vibrational) modes. We show that such systems can be described by a universal model in the vicinity of the nonlinear resonance involving all three …

      Cavity magnomechanics provides a readily controllable hybrid system, consisting of a cavity mode, magnon mode, and phonon mode, for quantum state manipulation and transfer. To implement a fast-and-robust state transfer between the hybrid photon-magnon mode and the phonon mode, we apply two accelerat…

These subradiant modes are characterized by a…
