Large-scale Tunable Liquid Lens-assisted VLC Systems under Random Receiver Orientation
Kapila W. S. Palitharathna, Constantinos Psomas, Gaofeng Pan +1 more·Jun 15, 2026
This paper investigates the performance of tunable liquid lens (TLL)-assisted receivers in large-scale visible light communication (VLC) systems under random receiver orientation. A simple electrowetting-based TLL architecture is proposed, capable of...
Hybrid Ferromagnet-SNSPDs: Single photon induced order-to-disorder transition in ferromagnets coupled to thin film superconductors
Leif Bauer, Daien He, Sathwik Bharadwaj +1 more·Jun 15, 2026
The development of midwave and longwave infrared single photon detectors is crucial for their emerging applications in spectroscopy, remote sensing, exoplanet detection, and free space quantum communications. However, existing sensors need to be oper...
Tripartite entanglement of remote atomic qubits
Isabella Goetting, Ashish Kalakuntla, Mikhail Shalaev +6 more·Jun 15, 2026
Distributed entanglement across multi-node quantum networks is essential for a wide range of quantum technologies, including modular quantum computers, distributed sensing and metrology, and multi-party secure communication protocols. Such large-scal...
Fermionic Hamiltonian engineering with local control
Özgün Kum, Matthias Zipper, Ludwig Mathey +1 more·Jun 15, 2026
Quantum simulators enable the exploration of complex quantum phenomena in condensed-matter systems by reproducing their dynamics on controllable quantum devices. However, experimental constraints often restrict the class of Hamiltonians that can be r...
Quantum Resources and Wigner Symmetry in Nucleon-Nucleon Scattering from Effective Field Theory
Ian Low, Thomas R. Richardson, Sokratis Trifinopoulos·Jun 15, 2026
We study quantum resources in the spin degrees of freedom, such as entanglement, stabilizer magic, and non-local magic, in low-energy nucleon-nucleon scattering through next-to-leading order in pionless effective field theory. Treating each nucleon s...
When Renormalisation Remembers: UV/IR Mixing as an Entanglement Bridge
Steven Abel·Jun 15, 2026
Renormalisation is traditionally understood to be a Wilsonian memoryless process in which ultraviolet (UV) degrees of freedom gradually decouple, leaving an autonomous infrared (IR) description. However this need not be the case: in UV/IR mixed theor...
Projected logical ensembles in surface codes via the random-matrix theory of quantum dots
Mircea Bejan, Jan Behrends, Max McGinley +1 more·Jun 15, 2026
Measurements underpin active quantum error correction (QEC) and have been recognized as a source of novel measurement-induced many-body phenomena. Here, we study the statistical properties of post-measurement logical states arising in QEC on topologi...
Grid-state deformation in a no-jump non-Hermitian bosonic dimer
B. M. Rodriguez-Lara, H. Ghaemi-Dizicheh, S. Dehdashti +3 more·Jun 15, 2026
We study the no-jump evolution of ideal grid states in a lossy bosonic dimer with differential decay. The effective non-Hermitian quadratic dynamics induces a complex symplectic flow in phase space that deforms both the primitive lattice vectors and ...
Bath memory as a precision resource in quantum transport
José Molina, Sheikh Parvez Mandal, Mahasweta Pandit +1 more·Jun 15, 2026
Structured baths can reshape transport fluctuations in mesoscopic quantum devices, yet a predictive criterion for when this enhances precision has been lacking. We propose a route towards such precision advantages by utilizing bath memory in coherent...
How Many Shots Are Enough for a Quantum Circuit?
Giuseppe Bisicchia, Alessandro Bocci, Ernesto Pimentel +1 more·Jun 15, 2026
Quantum algorithms require repeated circuit executions, known as shots, to estimate output distributions accurately. Determining the minimal number of shots needed to meet a target accuracy is crucial to reduce costs and resource usage, especially on...
Diagonal-Budgeted Trotterization for Efficient Quantum Hamiltonian Simulation
Srikar Chundury, Blake Burgstahler, Jiajia Li +2 more·Jun 15, 2026
Efficient classical simulation of quantum Hamiltonian dynamics is often bottlenecked by exponential state growth and the overhead of generic sparse linear algebra. We introduce diagonal-budgeted Trotterization, a structure-aware strategy that decompo...
The Optimal Rate Function in Covariant Quantum State Tomography
Arick Grootveld, Alexander Maloney, Jason Pollack +1 more·Jun 15, 2026
The problem of quantum tomography is to estimate an unknown quantum state $ρ$ from a measurement of $n$ copies of $ρ$. One can ask which tomography protocol, i.e.\ which choice of multi-copy measurement, gives the best possible estimate of $ρ$. To do...
Counterdiabatic Raman Atom Optics for Compact High-Sensitivity Gravimetry
Asad Ali, Hamid Arian Zad, Saif Al-Kuwari +6 more·Jun 15, 2026
Large-momentum-transfer (LMT) atom interferometry provides a route toward enhanced inertial sensitivity in compact quantum sensors, but its scalability is limited by the accumulation of pulse-transfer errors across long Raman pulse sequences. We inve...
Experimental quantum state learning with pairs of photons
C. Pria Dobney, Johan Henaff, Allen Kasum +5 more·Jun 15, 2026
Tomography allows one to estimate the density matrix describing the state an ensemble of quantum systems are prepared in (for example, polarization tomography determines the polarization state of a beam of identically prepared photons). In general, i...
Controlled Quantum Metrology with Anisotropic Heisenberg Spin Interactions under Intrinsic Decoherence
S. K. Singh, Jia-Xin Peng, Y-J Zhu +1 more·Jun 15, 2026
We theoretically investigate quantum parameter estimation in a two-qubit anisotropic Heisenberg spin system with Dzyaloshinskii-Moriya (DM) interaction in the presence of intrinsic decoherence described by the Milburn model. Using the Quantum Fisher ...
Analytic Benchmarks for Coherence-to-Entanglement Conversion under Post-Gate Noise in CNOT-Based Protocols
Asad Ali, H. Kuniyil, M. I. Hussain +3 more·Jun 15, 2026
Coherence-to-entanglement conversion transforms single-qubit superposition into a practical two-qubit resource, but noise limits this process in near-term quantum hardware. We derive closed-form benchmarks for a minimal CNOT primitive in which a cohe...
Neural dynamical systems on ferroelectric compute-in-memory for real-time forecasting
Keshava Katti, Adithya Selvakumar, Pratik Chaudhari +1 more·Jun 15, 2026
Neural dynamical systems are expressive temporal predictors that capture continuous-time dynamics through fine-grained state updates. However, this sequential structure maps poorly onto digital hardware optimized for dense matrix operations, a mismat...
Morphology-resolved scrambling in a chaotic quantum billiard
Pranaya Pratik Das·Jun 15, 2026
Chaotic quantum systems can retain spatial memory through scarred eigenstates, but whether these static structures control scrambling remains unclear. This work establishes a morphology-resolved connection between scarred eigenstates and eigenstate-r...

Liyang Sui, Hong-Hao Song, Sainan Huai +13 more·Jun 15, 2026
The three-dimensional (3D) Ising model is a foundational model in statistical physics and critical phenomena, yet its analytical intractability has long impeded the precise determination of universal critical exponents. While high-precision estimates...

Yi Liu, Xiaopeng Li, Zhen Liu +1 more·Jun 15, 2026
Determining non-equilibrium steady states (NESS) of open fermionic systems is a fundamental problem akin to finding ground states of closed systems. To address this, variational quantum algorithms can be used to solve the Lindblad master equation, mu...
