Generation of fully phase controlled two-photon entangled states
Ian Ford, Adrien Amour, Matthias Keller·Jan 23, 2026
Control over the internal states of trapped ions makes them the ideal system to generate single and two-photon states. Coupling a single ion to an optical cavity enables efficient emission of single photons into a single spatial mode and grants contr...

Hui Zhang, Yiming Ma, Yuancheng Zhan +6 more·Jan 23, 2026
Quantum technologies have surpassed classical systems by leveraging the unique properties of superposition and entanglement in photons and matter. Recent advancements in integrated quantum photonics, especially in silicon-based and lithium niobate pl...
Quantum phase estimation with optimal confidence interval using three control qubits
Kaur Kristjuhan, Dominic W. Berry·Jan 23, 2026
Quantum phase estimation is an important routine in many quantum algorithms, particularly for estimating the ground state energy in quantum chemistry simulations. This estimation involves applying powers of a unitary to the ground state, controlled b...
Gluing Randomness via Entanglement: Tight Bound from Second Rényi Entropy
Wonjun Lee, Hyukjoon Kwon, Gil Young Cho·Jan 23, 2026
The efficient generation of random quantum states is a long-standing challenge, motivated by their diverse applications in quantum information processing tasks. In this work, we identify entanglement as the key resource that enables local random unit...
The Double Covariance Model: A Stochastic Reconstruction of Quantum Entangled States via Interplay of Micro-Macro Time Scales
Andrei Khrennikov·Jan 22, 2026
This article presents a concrete mathematical framework for the generation of entangled quantum states from classical stochastic processes. We demonstrate that any density operator $ρ_{AB}$ of a composite system can be derived from the correlations b...
Quantum algorithm for simulating non-adiabatic dynamics at metallic surfaces
Robert A. Lang, Paarth Jain, Juan Miguel Arrazola +1 more·Jan 22, 2026
Non-adiabatic dynamics at molecule-metal interfaces govern diverse and technologically important phenomena, from heterogeneous catalysis to dye-sensitized solar energy conversion and charge transport across molecular junctions. Realistic modeling of ...
A First Demonstration of the SQUAT Detector Architecture: Direct Measurement of Resonator-Free Charge-Sensitive Transmons
H. Magoon, T. Aralis, T. Dyson +18 more·Jan 22, 2026
The Superconducting Quasiparticle-Amplifying Transmon (SQUAT) is a new sensor architecture for THz (meV) detection based on a weakly charge-sensitive transmon directly coupled to a transmission line. In such devices, energy depositions break Cooper p...
Quantum Cellular Automata on a Dual-Species Rydberg Processor
Ryan White, Vikram Ramesh, Alexander Impertro +6 more·Jan 22, 2026
As quantum devices scale to larger and larger sizes, a significant challenge emerges in scaling their coherent controls accordingly. Quantum cellular automata (QCAs) constitute a promising framework that bypasses this control problem: universal dynam...
Purcell enhanced electroluminescence of a unipolar light emitting quantum device at 10 micron
Marta Mastrangelo, Djamal Gacemi, Axel Evirgen +7 more·Jan 21, 2026
Efficient generation of radiation in the mid- and far- infrared relies primarily on lasers and coherent nonlinear optical phenomena driven by lasers. This wavelength range lacks of luminescent devices because the spontaneous emission rate becomes muc...
