Complexity phase transition for continuous-variable cluster state
Byeongseon Go, Hyunseok Jeong, Changhun Oh·Apr 9, 2026
Continuous-variable (CV) cluster states offer a promising platform for large-scale measurement-based quantum computations (MBQC). However, finite squeezing inevitably introduces Gaussian noise during MBQC. While fault-tolerant MBQC schemes exist in p...

Integral transformations are useful mathematical tool to work out signals and wave-packets in electronic devices. They may be used in software protocols. Necessary knowledge may come from quantum field theory, in particular from quantum chromodynamic...
Ghost imaging with zero photons
Meixue Chen, Yiqi Song, Yu Gu +8 more·Apr 9, 2026
Ghost imaging was first demonstrated with entangled photon pairs and well-known for its peculiar properties. The signal beam that illuminates the object possesses no spatial resolution, whereas the reference beam, which never interacts with the objec...

Di Fang, Xiaoxu Wu·Apr 9, 2026
Efficiently simulating many-body quantum systems with Coulomb interactions is a fundamental question in quantum physics, quantum chemistry, and quantum computing, yet it presents unique challenges: the Hamiltonian is an unbounded operator (both kinet...

This paper presents a pilot study exploring the effects of an olfactory stimulus (smoke) for a Virtual Reality game designed to support wildfire evacuation preparedness. Participants (N=18) were split evenly into either a smoke or a control condition...
Control-centric quantum noise spectroscopy of time-ordered polyspectra
Kaiah Steven, Elliot Coupe, Qi Yu +1 more·Apr 9, 2026
Precise environmental-noise characterisation in open quantum systems is a key step toward high-fidelity quantum control and targeted decoherence suppression in computing and sensing applications. Non-parametric quantum noise spectroscopy (QNS) provid...
A Thermodynamic SU(1,1) Witness Framework for Double-Quantum NMR Signals in Neural Tissue
Christian Kerskens·Apr 8, 2026
Entanglement criteria based on variances or Fisher information are well developed for compact collective spin algebras, but their extension to non-compact dynamical sectors is less straightforward. In particular, double-quantum (DQ) observables assoc...

On Lorentzian symmetries of quantum information
James Fullwood, Vlatko Vedral, Edgar Guzmán-González·Apr 8, 2026
A foundational result in relativistic quantum information theory due to Peres, Scudo, and Terno, is that von Neumann entropy is not Lorentz invariant. Motivated by the "It from Qubit" paradigm, here we show that Lorentzian symmetries of quantum infor...
Optimal Quantum State Testing Even with Limited Entanglement
Chirag Wadhwa, Sitan Chen·Apr 8, 2026
In this work, we consider the fundamental task of quantum state certification: given copies of an unknown quantum state $ρ$, test whether it matches some target state $σ$ or is $ε$-far from it. For certifying $d$-dimensional states, $Θ(d/ε^2)$ copies...
