Efficient Energy-Constrained Semi-Device-Independent QRNG with an Integrated Heterodyne Receiver
Mattia Sabatini, Carles Roch i Carceller, Tommaso Bertapelle +10 more·Jun 22, 2026
Semi-device-independent QRNG frameworks represent a particularly attractive approach, combining strong security guarantees with high randomness generation rates while relying only on reduced and practical physical assumptions. A recently proposed app...
Quantum Advantage in Tolerant Junta Testing
Avishay Tal, Weiqiang Yuan·Jun 22, 2026
We establish the first super-polynomial quantum advantage for the tolerant junta testing problem in the adaptive setting. Specifically, we show that within a certain parameter regime, tolerant $k$-junta testing with high precision can be solved using...
Entropic Uncertainty Relations for Mutually Unbiased Operator Frames
Jesni Shamsul Shaari, Stefano Mancini·Jun 22, 2026
We develop an operator-frame formulation of entropic uncertainty relations in the Hilbert-Schmidt space of operators. For general continuous indexed operator frames, we derive an entropic uncertainty relation for the associated coefficient distributi...
General-Purpose Nonlinear Function Approximation via Linear Integrated Photonics
Ayana Mizuno, Isamu Takai, Makoto Nakai +3 more·Jun 22, 2026
Photonic computing has emerged as a promising platform for accelerating artificial intelligence workloads by enabling low-latency and energy-efficient linear operations such as vector-matrix multiplication. However, scalable on-chip high-order nonlin...
Angular-time evolution and edge-spin dynamics in the Haldane phase of the S=1 bilinear-biquadratic chain
Takuma Kaise, Kouichi Okunishi·Jun 22, 2026
We investigate the angular-time evolution -- a parameter-time evolution generated by the entanglement Hamiltonian -- for the bipartitioned ground state of the S=1 bilinear-biquadratic chain under the open boundary condition with the up edge spin. Usi...
Understanding Squeezed States of Light Through Wigner's Phase-Space
Sibel Baskal, Marilyn E. Noz·Jun 22, 2026
This paper starts with the transition from classical physics to quantum mechanics which was greatly aided by the concept of phase space. The role of canonical transformations in quantum mechanics is addressed. The Wigner phase-space distribution func...
An Efficient and Perfect Secret Sharing Scheme on a Class of Non-Maximal Quantum Access Structure
Lei Li, Zhi Li·Jun 22, 2026
Quantum secret sharing is one of the core security technologies in the field of quantum communication. Aiming at the problems of high quantum resource consumption and the difficulty in balancing security and efficiency existing in current quantum sec...
Satellite Mission Planning with Rydberg Atoms
Michel Nowak, Benjamin Marchand, Yassine Naghmouchi +4 more·Jun 22, 2026
Quantum computers relying on cold atoms are being built and promise a high flexibility in the way information in encoded into the physical system. In particular, the analog mode is spiking interest in the field of optimization as a classically intrac...
Scalable Online Flight Trajectory Optimization via Sequential Quadratic Programming for Urban Air Mobility in Ultra Low-Altitude Airspace
Josue N. Rivera, Bohang Liang, Chen Lv +1 more·Jun 22, 2026
As Urban Air Mobility (UAM) scales toward high-density operations, generating collision-free trajectories within complex 3D cityscapes is a critical safety requirement. This paper proposes a scalable Sequential Quadratic Programming (SQP) framework t...
Adversarial Reinforcement Learning for Adaptive Eavesdropping in BB84 Quantum Key Distribution
Ramon Jose C. Bagunu·Jun 22, 2026
BB84 quantum key distribution derives its security from a physical guarantee that any eavesdropper disturbs the channel in a statistically detectable way. Prior work evaluates this by assuming Eve attacks at a fixed, analytically optimized rate. We e...
Chaos Generation and Control with Molecular Optomechanical System
Hui-Hui Xu, Jian-zhuang Wu, Lei-Bo Deng +2 more·Jun 22, 2026
Chaos is central to secure communication and physical random-number generation. Conventional cavity-optomechanical implementations, however, usually rely on weak single-photon optomechanical coupling and low-frequency mechanical modes, so access to d...
Bunny Codes: Broadening Superconducting Quantum Error Correction Capability through Advanced Control Engineering
Runshi Zhou, Xingye Yuan, Linghang Kong +4 more·Jun 22, 2026
Drawing on advances in superconducting qubit control schemes that unlock enriched native gate sets at the hardware level, we systematically examine how harnessing this enlarged physical two-qubit gate pool -- specifically CNOT and CXSWAP -- streamlin...
When the Learning With Errors Problem Meets the Coherent Ising Machine: A Penalty-Free Algorithm-Hardware Co-Design
Shuxian Jiang·Jun 22, 2026
The Learning With Errors (LWE) problem constitutes the mathematical foundation of modern Post-Quantum Cryptography (PQC). Cryptanalysis of LWE ranges from classical lattice reduction to machine learning and quantum-classical hybrids. We propose CIM-B...
Linear optical Bell state measurement for rotation-symmetric cat codes
Issa Oe, Suguru Endo, Rui Asaoka·Jun 22, 2026
Rotation-symmetric cat (RS-cat) codes are a bosonic-code platform for quantum information processing, combining finite-energy realizability with robustness against photon loss through their discrete rotational symmetry. For applications in long-dista...
Isometrization of Tensor Network States via Gauge Propagation
Zhiyu Jiang, Hiroshi Ueda·Jun 22, 2026
We introduce a gauge-propagation approach for approximately converting generic tensor-network states into an isometric tensor-network state form with a prescribed orthogonality center. In one dimension, this propagation is exact because the non-isome...
Integrating Heterogeneous Digital Twins in Federated Ecosystems
Christian Vergara-Marcillo, Rami Bahsoon, Nikos Tziritas +3 more·Jun 22, 2026
Digital Twins (DTs) are increasingly used to virtualise physical systems at different scales, enabling monitoring, simulation, and predictions to support decision-making. However, while individual DTs are effective in stand-alone settings, ecosystem-...
Wigner-Negative Magnon Steady States from Incoherent Qubit Pumping
Yan Liu, Jiahua Li·Jun 22, 2026
We show that incoherently pumped qubits can realize a cascaded dissipative mechanism for stabilizing Wigner-negative magnon steady states. The mechanism combines qubit pumping with dispersive magnon-number selectivity to direct the steady-state popul...

Protecting Qubits from Purcell Decay via Permanent Dipoles
Alex Krasnok·Jun 22, 2026
Reading out a qubit often requires coupling it to a resonator, but that same resonator can also give the qubit an extra path to decay. Here, we study a way to reduce this loss using a built-in permanent electric dipole. The dipole shifts the cavity f...
