Deterministic single-photon source over the terahertz regime
Caspar Groiseau, Miguel Á. Martínez-García, Diego Martín-Cano +1 more·Sep 30, 2025
We propose a deterministic single-photon source in the terahertz (THz) regime, triggered by a sequence of coherent optical pulses. The scheme leverages the permanent dipole moment of a single-polar quantum emitter to induce THz transitions between op...

Paniz Foshat, Samane Kalhor, Shima Poorgholam-khanjari +3 more·Sep 30, 2025
Advancing large-scale quantum computing requires superconducting circuits that combine long coherence times with compatibility with semiconductor technology. We investigate niobium nitride (NbN) coplanar waveguide resonators integrated with Si/SiGe q...
PhotonIDs: ML-Powered Photon Identification System for Dark Count Elimination
Karl C. Linne, Sho Uemura, Yue Ji +6 more·Sep 30, 2025
Reliable single photon detection is the foundation for practical quantum communication and networking. However, today's superconducting nanowire single photon detector(SNSPD) inherently fails to distinguish between genuine photon events and dark coun...
Hybrid Quantum-Classical Optimisation of Traveling Salesperson Problem
Christos Lytrosyngounis, Ioannis Lytrosyngounis·Sep 30, 2025
The Traveling Salesperson Problem (TSP), a quintessential NP-hard combinatorial optimisation challenge, is vital for logistics and network design but limited by exponential complexity in large instances. We propose a hybrid quantum-classical framewor...
Dynamics of Majorana zero modes across hybrid Kitaev chain
Rajiv Kumar, Rohit Kumar Shukla, Levan Chotorlishvili +1 more·Sep 30, 2025
The Kitaev chain has been extensively explored in the context of uniform couplings, with studies focusing either on purely nearest-neighbor interactions or on systems dominated by long-range superconducting pairing. Building on these investigations, ...
Toward Quantum-Enabled Biomarker Discovery: An Outlook from Q4Bio
Dhirpal Shah, Mariesa Teo, Ryan A. Robinett +12 more·Sep 30, 2025
We present a case study and forward-looking perspective on co-design for hybrid quantum-classical algorithms, centered on the goal of empirical quantum advantage (EQA), which we define as a measurable performance gain using quantum hardware over stat...
Perturbation theory, irrep truncations, and state preparation methods for quantum simulations of SU(3) lattice gauge theory
Praveen Balaji, Cianan Conefrey-Shinozaki, Patrick Draper +4 more·Sep 30, 2025
We study methods for efficient preparation of approximate ground states of $SU(3)$ lattice gauge theory on quantum hardware. Working in a variant of the electric basis, we introduce a refinement of the irrep truncation based on the energy density of ...
Dynamical Acoustic Control of Resonance Fluorescence from a Strongly Driven Two-Level System
Yuan Zhan, Zixuan Wang, Richard P. Mirin +2 more·Sep 30, 2025
Resonance fluorescence from a single two-level system is a cornerstone of quantum optics. In the strong driving regime, its emission spectrum exhibits the iconic Mollow triplet, with each spectral component corresponding to a transition between disti...
Hybrid Schemes of NIST Post-Quantum Cryptography Standard Algorithms and Quantum Key Distribution for Key Exchange and Digital Signature
Abel C. H. Chen·Sep 30, 2025
Since the security of post-quantum cryptography (PQC) algorithms is based on the hardness of mathematical problems, while the security of quantum key distribution (QKD) relies on the fundamental principles of quantum physics, each approach possesses ...

Preparing magnon nonclassical states is a central topic in the study of quantum magnonics. Here we propose to generate magnon squeezed states in a hybrid cavity-magnon-qubit system by engineering an effective Rabi-type magnon-qubit interaction. This ...
Quantum Approximate Optimization Algorithm: Performance on Simulators and Quantum Hardware
Abyan Khabir Irfan, Chansu Yu·Sep 29, 2025
Running quantum circuits on quantum computers does not always generate "clean" results, unlike on a simulator, as noise plays a significant role in any quantum device. To explore this, we experimented with the Quantum Approximate Optimization Algorit...
