Physics-Constrained Compressed Sensing for Quantum Sensing in the Data-Starved Regime
Amir Kalev
Quantum sensors promise measurement sensitivities that can scale at the Heisenberg limit, but in practice their performance is often degraded by noise, finite sampling, and impleme…
Geometric Decoherence Time in Lindbladian Dynamics
Rishabh Jha, Stephan Haas, Abhinav Prem
The onset of decoherence in open many-body systems lacks a dynamical timescale grounded in the loss of bipartite entanglement. Here, we introduce the $tim…
Plethysm is in #BQP
Matthias Christandl, Aram W. Harrow, Greta Panova +2
Some representation-theoretic multiplicities, such as the Kostka and the Littlewood-Richardson coefficients, admit a combinatorial interpretation that places their computation in t…
Generation of spin-squeezed states using dipole-coupled spins
Yifan Song, Nabiha Hasan, Susumu Takahashi
Spins in solids and molecules are promising for applications of quantum sensing technology. The sensitivity of the quantum sensing depends on how precisely spin observables can be…
In situ quantum verification of polarization-stabilized optical channels
Matthew L. Stevens, Noah I. Wasserbeck, Zachary Goisman +8
The active stabilization of polarization channels is a task of growing importance as quantum networks move to deployed demonstrations over existing fiber infrastructure. However, t…
Fundamental Limits to Cat-Code Qubits from Chaos-Assisted Tunneling
Lionel E. Martínez, Ignacio García-Mata, Diego A. Wisniacki
We show that chaos-assisted tunneling (CAT) imposes an intrinsic limit to the protection of Kerr-cat qubits. In the static effective description, tunneling between the quasidegener…
Robust Universal Braiding with Non-semisimple Ising Anyons
Filippo Iulianelli, Sung Kim, Joshua Sussan +1
Non-semisimple extensions of the Ising anyon model developed in our previous work enable universal topological quantum computation via braiding alone, overcoming the Clifford-only…
Theory of quantum comb enhanced interferometry
Haowei Shi, Quntao Zhuang
Optical frequency combs, named for their comb-like peaks in the spectrum, are essential for various sensing applications. As the technology develops, its performance has reached th…
A Fundamental Bound for Robust Quantum Gate Control
Robert L. Kosut, Daniel A. Lidar, Herschel Rabitz
We derive a universal performance limit for coherent quantum control in the presence of modeled and unmodeled uncertainties. For any target unitary that is implementable in the…
Bounds on QCA Lattice Spacing from Data on Lorentz Violation
Leonard Mlodinow, Todd A. Brun
Recent work has demonstrated that discrete quantum walks, when extended to quantum cellular automata (QCA), can, in the continuum limit, reproduce relativistic wave equations and q…
Continuous quantum correction on Markovian and Non-Markovian models
Juan Garcia Nila, Todd A. Brun
We investigate continuous quantum error correction, comparing performance under a Markovian error model to two distinct non-Markovian models. The first non-Markovian model involves…
Quantum transduction via generalized continuous-variable teleportation
Quntao Zhuang
Quantum transduction converts quantum states between different frequencies. Similarly, quantum teleportation transfers quantum states between different systems. While often appreci…
Scaling Laws of Quantum Information Lifetime in Monitored Quantum Dynamics
Bingzhi Zhang, Fangjun Hu, Runzhe Mo +3
Quantum information is typically fragile under measurements and environmental coupling. Remarkably, we find that its lifetime can scale exponentially with system size when the envi…
Physical-Layer Machine Learning with Multimode Interferometric Photon Counting
Jia-Jin Feng, Anthony J. Brady, Quntao Zhuang
The learning of the physical world relies on sensing and data post-processing. When the signals are weak, multidimensional and correlated, the performance of learning is often bott…
Computational Complexity and Simulability of Non-Hermitian Quantum Dynamics
Brian Barch, Daniel Lidar
Non-Hermitian (NH) quantum systems demonstrate striking differences from their Hermitian counterparts, leading to claims of NH advantage in areas ranging from metrology to entangle…
Integrability and Chaos via fractal analysis of Spectral Form Factors: Gaussian approximations and exact results
Lorenzo Campos Venuti, Jovan Odavić, Alioscia Hamma
It is well known that the spectral form factor (SFF) of a possibly degenerate many-body Hamiltonian can be identified with a planar random walk taking steps of unequal length. In t…
Quantum Electrodynamics from Quantum Cellular Automata, and the Tension Between Symmetry, Locality and Positive Energy
Todd A. Brun, Leonard Mlodinow
We show that free QED is equivalent to the continuous-space-and-time limit of Fermi and Bose lattice quantum cellular automata theories derived from quantum random walks satisfying…
Selective Filtering of Photonic Quantum Entanglement via Anti-Parity-Time Symmetry
Mahmoud A. Selim, Max Ehrhardt, Yuqiang Ding +8
Entanglement is a key resource for quantum computing, sensing, and communication, however it is highly susceptible to decoherence. To address this, quantum optics has explored filt…
An Exact Link between Nonlocal Nonstabilizerness and Operator Entanglement
Faidon Andreadakis, Paolo Zanardi
Nonstabilizerness is a quantum property of states associated with the non-Clifford resources required for their preparation. As a resource, nonstabilizerness complements entangleme…
Quantum Optimization Benchmarking Library - The Intractable Decathlon
Thorsten Koch, David E. Bernal Neira, Ying Chen +24
Through recent progress in hardware development, quantum computers have advanced to the point where benchmarking of (heuristic) quantum algorithms at scale is within reach. Particu…
Boundary Conditions for the Entanglement Cut in 2D Conformal Field Theories
Ananda Roy, Sergei L. Lukyanov, Hubert Saleur
The entanglement spectra for a subsystem in a spin chain fine-tuned to a quantum-critical point contains signatures of the underlying quantum field theory that governs its low-ener…
