Using near-flat-band electrons for read-out of molecular spin qubit entangled states
Christian Bunker, Silas Hoffman, Shuanglong Liu +2 more·Feb 24, 2026
While molecular spin qubits (MSQs) are a promising platform for quantum computing, read-out has been largely limited to electron paramagnetic resonance which is often slow and requires a global system drive. Moreover, because one prerequisite for the...
Coherent Quantum Evaluation of Collider Amplitudes for Effective Field Theory Constraints
Yacine Haddad, Kaidi Xu, Vincent Croft +2 more·Feb 24, 2026
Precision measurements at electron-positron colliders provide stringent tests of the Standard Model and powerful probes of possible higher-dimensional interactions. We present a hybrid quantum-classical framework for computing leading-order helicity ...
Optical repumping and atom number balancing in a two-color MOT
Shubha Deutschle, Lőrinc Sárkány, Milán János Negyedi +3 more·Feb 24, 2026
We study a novel repumping transition for $^{88}$Sr atoms trapped in a 'blue' magneto-optical trap. We show that, while the repumping efficiency is about three orders of magnitude smaller than for traditional schemes, it is sufficient for recycling a...
Detecting Higher Berry Phase via Boundary Scattering
Chih-Yu Lo, Xueda Wen·Feb 24, 2026
Higher Berry phase has recently been proposed to study the topology of the space of gapped many-body quantum systems. In this work, we develop a boundary-scattering approach to detect higher Berry phases in one-dimensional gapped free-fermion systems...
Ab Initio Random Matrix Theory of Molecular Electronic Structure
Zhen Tao, Victor Galitski·Feb 24, 2026
We use ab initio electronic-structure methods to investigate random-matrix theory (RMT) universality in molecular electronic structure. Using single-reference electronic structure methods, including Hartree-Fock, configuration-interaction singles (CI...
Teleportation transition of surface codes on a superconducting quantum processor
Yiren Zou, Hong-Kuan Xia, Aosai Zhang +32 more·Feb 24, 2026
The topological surface code is a leading candidate for harnessing long-range entanglement to protect logical quantum information against errors, and teleportation of logical states is desirable for robust quantum information processing. Nevertheless...
Random Acceleration Noise on Stern-Gerlach Interferometry in a Harmonic Trap
Sneha Narasimha Moorthy, Andrew Geraci, Sougato Bose +1 more·Feb 24, 2026
We analyze decoherence in a one-loop Stern--Gerlach--type matter-wave interferometer for a massive nanoparticle embedded with a nitrogen vacancy (NV)-centred nanodiamond evolving under an effective harmonic-oscillator dynamics in a magnetic-field gra...
Topological Floquet Green's function zeros
Elio J. König, Aditi Mitra·Feb 24, 2026
Motivated by recent advances in digital quantum emulation using noisy intermediate-scale quantum (NISQ) devices and an increased interest in topological Green's function zeros in condensed matter systems, we here study Green's function zeros in topol...
Exact quantum transport in non-Markovian open Gaussian systems
Guglielmo Pellitteri, Vittorio Giovannetti, Vasco Cavina·Feb 24, 2026
We build an exact framework to evaluate heat, energy, and particle transport between Gaussian reservoirs mediated by a quadratic quantum system. By combining full counting statistics with newly developed non-Markovian master equation approaches, we i...
Reducing the Gate Count with Efficient Trotter-Suzuki Schemes
Marko Maležič, Johann Ostmeyer·Feb 24, 2026
Hamiltonian formulations of lattice field theories provide access to real-time dynamics, but their simulation is difficult to implement efficiently. Trotter-Suzuki decompositions are at the center of time evolution computation, either on quantum hard...
Effect of symmetry breaking on altermagnetism in CrSb and Formation of fragmented nodal curves
Arindom Das, Arijit Mandal, Nayana Devaraj +1 more·Feb 24, 2026
Phenomena concerning altermagnets have opened up a window for unconventional analysis of the momentum space spin polarization (MSSP) of antiferromagnetic materials. Taking the example of one of the widely investigated altermagnets, CrSb, we explore t...
Quantum Approximate Optimization for Decoding of Low-Density Parity-Check Codes
Krishnakanta Barik, Goutam Paul·Feb 24, 2026
Decoding Low-Density Parity-Check (LDPC) codes is a fundamental problem in coding theory, and Belief Propagation (BP) is one of the most popular methods for LDPC code decoding. However, BP may encounter convergence issues and suboptimal performance, ...
On Hydrodynamic Formulations of Quantum Mechanics and the Problem of Sparse Ontology
Aric Hackebill, Bill Poirier·Feb 24, 2026
Hydrodynamic reformulations of the Schrödinger equation suggest an interpretation of quantum mechanics in terms of a fluid flowing on configuration space. In the discrete hydrodynamic view, this fluid is not fundamental but emerges from many underlyi...
Quantum feedback algorithms for DNA assembly using FALQON variants
Pedro M. Prado, Lucas A. M. Rattighieri, Rafael Simões do Carmo +6 more·Feb 24, 2026
Reconstructing DNA sequences without a reference, known as de novo assembly, is a complex computational task involving the alignment of overlapping fragments. To address this problem, a usual strategy is to map the assembly to a Quadratic Unconstrain...
Correcting coherent quantum errors by going with the flow
Wayne M. Witzel, Anand Ganti, Tzvetan S. Metodi·Feb 24, 2026
The performance of a given quantum error correction (QEC) code depends upon the noise model that is assumed. Independent Pauli noise, applied after each quantum operation, is a simplistic noise model that is easy to simulate and understand in the con...
Quantum Coherence of Top Quark Pairs Produced at LHC
Saeed Haddadi, Majid Azizi, Artur Czerwinski·Feb 24, 2026
We study quantum coherence in top-antitop production at the LHC by comparing Standard Model predictions with CMS data across different kinematic regimes. Theory and experiment are statistically consistent in the near-threshold and boosted central reg...
Asynchronous Multi-photon Interference for Quantum Networks
Baghdasar Baghdasaryan, Karen Lozano-Méndez, Markus Leipe +11 more·Feb 24, 2026
Advanced quantum communication protocols require high-visibility quantum interference between photons generated at distant nodes, which places stringent demands on optical synchronization. Conventionally, synchronization of optical wave packets relie...
Restriction-Based Certificate of Bipartite Schmidt Rank in Hypergraph States
C. Fajardo, M. Paraschiv·Feb 24, 2026
We investigate bipartite entanglement in qubit hypergraph states across an arbitrary fixed bipartition. Using the real equally weighted (REW) representation, the Schmidt rank across the cut can be computed as the real rank of a phase-cleaned cross-cu...
Telemetry-Based Server Selection in the Quantum Internet via Cross-Layer Runtime Estimation
Masaki Nagai, Hideaki Kawaguchi, Shin Nishio +1 more·Feb 24, 2026
The Quantum Internet will allow clients to delegate quantum workloads to remote servers over heterogeneous networks, but choosing the server that minimizes end-to-end execution time is difficult because server processing, feedforward classical commun...
Internal dynamics and guided motion in general relativistic quantum interferometry
Thomas B. Mieling·Feb 24, 2026
The coupling between internal degrees of freedom of quantum systems and their overall motion in an external gravitational field plays a central role in multiple extensions of Einstein's equivalence principle to quantum physics. While previous models ...
