Open Quantum Systems Driven by Chirped Pulses: Quantized versus Semiclassical Fields and the Validity of the Rotating-Wave Approximation
Justin Zhengjie Tan, Frank Großmann, Yiying Yan +2
Population transfer via chirped rapid adiabatic passage is studied using open quantum and semiclassical models, with and without the rotating-wave approximation. A time-dependent v…
Detecting entanglement from few partial transpose moments and their decay via weight enumerators
Daniel Miller, Jens Eisert
The -PPT criterion is an experimentally viable relaxation of the well-known positive partial transposition (PPT) criterion for the certification of quantum entanglement. Recen…
Fundamental Limits of Non-Hermitian Sensing from Quantum Fisher Information
Jan Wiersig, Stefan Rotter
Exceptional points (EPs) exhibit strongly enhanced spectral responses and are therefore promising candidates for sensing applications. Whether these non-Hermitian degeneracies prov…
Harnessing subspace controllability: Dynamical generation of Dicke states in Heisenberg-coupled qubit arrays with a single local control
Vladimir M. Stojanovic, Tommaso Calarco, Andrea Muratori
We explore the feasibility of realizing Dicke states in qubit arrays with always-on isotropic Heisenberg coupling between adjacent qubits, assuming a single Zeeman-type control act…
Passive quantum state transfer in a dispersion-engineered waveguide
Zeyu Kuang, Oliver Diekmann, Lorenz Fischer +2
High-fidelity state transfer is fundamentally limited by time-reversal symmetry: one qubit emits a photon with a certain temporal pulse shape, whereas a second qubit requires the t…
Unifying Qubit Routing Across Diverse Quantum ISAs via Canonical Representation
Zhaohui Yang, Kai Zhang, Xinyang Tian +6
Qubit mapping/routing is a critical stage in compilation for both near-term and fault-tolerant quantum computers, yet existing scalable methods typically impose several times the r…
Anticoncentration is (almost) all you need
Markus Heinrich, Jonas Haferkamp, Ingo Roth +1
Until very recently, it was generally believed that the (approximate) 2-design property is strictly stronger than anticoncentration of random quantum circuits, mainly because it wa…
Krylov Complexity Under Hamiltonian Deformations and Toda Flows
Kazutaka Takahashi, Pratik Nandy, Adolfo del Campo
The quantum dynamics of a complex system can be efficiently described in Krylov space, the minimal subspace in which the dynamics unfolds. We apply the Krylov subspace method for H…
Information-thermodynamic bounds on precision in interacting quantum systems
Ryotaro Honma, Tan Van Vu
The thermodynamic uncertainty relation quantifies a trade-off between the relative fluctuations of trajectory currents and the thermodynamic cost, indicating that the current preci…
Entanglement and optimization within autoregressive neural quantum states
Andrew Jreissaty, Hang Zhang, Jairo C. Quijano +2
Neural quantum states (NQSs) are powerful variational ansätze capable of representing highly entangled quantum many-body wavefunctions. While the average entanglement properties of…
Intrinsic non-Hermitian topological phases
Ken Shiozaki
We study the interplay of non-Hermitian topological phases under point- and line-gap conditions. Using natural homomorphisms from line-gap to point-gap phases, we distinguish extri…
Universal Precision Limits in General Open Quantum Systems
Tan Van Vu, Ryotaro Honma, Keiji Saito
The intuition that the precision of observables is constrained by thermodynamic costs has recently been formalized through thermodynamic and kinetic uncertainty relations. While su…
Biorthogonal Neural Network Approach to Two-Dimensional Non-Hermitian Systems
Massimo Solinas, Brandon Barton, Yuxuan Zhang +2
Non-Hermitian quantum many-body systems exhibit a rich array of physical phenomena, including non-Hermitian skin effects and exceptional points, that remain largely inaccessible to…
Higher spin Richardson-Gaudin model with time-dependent coupling: Exact dynamics
Suvendu Barik, Lieuwe Bakker, Vladimir Gritsev +2
We determine the exact asymptotic many-body wavefunction of a spin- Richardson-Gaudin model with a coupling inversely proportional to time, for time evolution starting from the…
Entanglement production in the Sachdev-Ye-Kitaev Model and its variants
Tanay Pathak, Masaki Tezuka
Understanding how quantum chaotic systems generate entanglement can provide insight into their microscopic chaotic dynamics and can help distinguish between different classes of ch…
Optomechanical systems with linear and quadratic position couplings: Dynamics and optimal estimation
Yaqing Xy Wang, Claudio Sanavio, József Zsolt Bernád
We study the dynamics of an optomechanical system consisting of a single-mode optical field coupled to a mechanical oscillator, where the nonlinear interaction includes both linear…
How to use quantum computers for biomolecular free energies
Jakob Günther, Thomas Weymuth, Moritz Bensberg +18
Free energy calculations are at the heart of physics-based analyses of biochemical processes. They allow us to quantify molecular recognition mechanisms, which determine a wide ran…
Measurement induced scrambling and emergent symmetries in random circuits
Haifeng Tang, Hong-Yi Wang, Zhong Wang +1
Quantum entanglement is affected by unitary evolution, which spreads the entanglement through the whole system, and also by measurements, which usually tends to disentangle subsyst…
Harnessing Photon Indistinguishability in Quantum Extreme Learning Machines
Malo Joly, Adrian Makowski, Baptiste Courme +6
Recent advancements in machine learning have led to an exponential increase in computational demands, driving the need for innovative computing platforms. Quantum computing, with i…
Flow to Nishimori universality in weakly monitored quantum circuits with qubit loss
Malte Pütz, Romain Vasseur, Andreas W. W. Ludwig +2
In circuit-based quantum state preparation, qubit loss and coherent errors are circuit imperfections that imperil the formation of long-range entanglement beyond a certain threshol…
Non-Gaussian Noise Magnetometry Using Local Spin Qubits
Jonathan B. Curtis, Amir Yacoby, Eugene Demler
Atomic scale qubits, as may be realized in nitrogen vacancy (NV) centers in diamond, offer the opportunity to study magnetic field noise with nanometer scale spatial resolution. Us…
