quantum-computingInfleqtion’s Quantum Timing Achieves 40x Improvement Over GPS, Validated on Quantum Corridor
Infleqtion has achieved a 40x improvement in timing precision over GPS, a breakthrough demonstrated on the Quantum Corridor, a dedicated fiber-optic network spanning 21.8 kilometers between Chicago and Hammond, IN. This leap forward, utilizing Infleqtion’s Tiqker quantum optical atomic clock, promises to bolster the security and resilience of critical digital infrastructure—from financial trading to AI—currently vulnerable to GPS disruption. “As digital infrastructure scales, relying on a single source of time is a growing risk,” said Pranav Gokhale, CTO at Infleqtion. This successful deployment over existing fiber, validated across a live urban network, signals a move towards quantum-based timing services and reduces dependence on potentially compromised satellite signals, paving the way for a new era of precise synchronization. Infleqtion’s Tiqker Clock Achieves Picosecond Synchronization on Quantum Corridor Infleqtion has demonstrated picosecond-level synchronization of its Tiqker quantum optical atomic clock across 21.8 kilometers of live urban fiber on the Quantum Corridor network, connecting Chicago’s ORD10 Data Center to a facility in Hammond, IN. This achievement marks a significant step toward bolstering the resilience of critical digital infrastructure currently reliant on vulnerable GPS signals. The demonstration utilized a purpose-built network, Quantum Corridor, engineered with tightly controlled parameters—a defined 1310–1550 nm single-mode fiber profile and a protected physical route—to preserve optical and temporal stability. The Tiqker clock, a rack-mounted system, maintained synchronization even amidst typical network activity and environmental fluctuations. Measured results revealed up to a 40 times improvement over conventional GPS-based timing, and superior performance compared to cesium beam clocks, particularly over critical short to medium timescales.

quantum-computingU(1) lattice gauge theory and string roughening on a triangular Rydberg array
--> Quantum Physics arXiv:2602.06123 (quant-ph) [Submitted on 5 Feb 2026] Title:U(1) lattice gauge theory and string roughening on a triangular Rydberg array Authors:Lisa Bombieri, Torsten V. Zache, Hannes Pichler, Daniel González-Cuadra View a PDF of the paper titled U(1) lattice gauge theory and string roughening on a triangular Rydberg array, by Lisa Bombieri and 3 other authors View PDF HTML (experimental) Abstract:Lattice gauge theories (LGTs) describe fundamental interactions in particle physics. A central phenomenon in these theories is confinement, which binds quarks and antiquarks into hadrons through the formation of string-like flux tubes of gauge fields. Simulating confinement dynamics is a challenging task, but recent advances in quantum simulation are enabling the exploration of LGTs in regimes beyond the reach of classical computation. For analog devices, a major difficulty is the realization of strong plaquette interactions, which generate string fluctuations that can drive a roughening transition. Understanding string roughening -- where strong transversal functions lead to an effective restoration of translational symmetry at long distances -- is of central importance in the study of confinement. In this work, we show that string roughening emerges naturally in an analog Rydberg quantum simulator. We first map a triangular Rydberg array onto a (2+1)D U(1) LGT where plaquette terms appear as first-order processes. We study flux strings connecting static charges and demonstrate that, near a deconfined quantum critical point, the string exhibits logarithmic growth of its transverse width as the separation between charges increases, along with the universal Lüscher correction to the confining potential -- both signatures of string roughening. Finally, we investigate the real-time dynamics of an initially rigid string, observing large fluctuations after quenching into the roughening regime, as well as string breaking via particle-pair creation.

quantum-computingDark matter could be masquerading as a black hole at the Milky Way’s core
Science News from research organizations Dark matter could be masquerading as a black hole at the Milky Way’s core The heart of the Milky Way may be hiding something far stranger than a supermassive black hole. Date: February 7, 2026 Source: Royal Astronomical Society Summary: Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the center and the slower, graceful rotation of material far beyond. This dark matter structure would have a compact core that pulls on nearby stars like a black hole, surrounded by a broad halo shaping the galaxy’s outer motion. Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY The Milky Way’s core may be powered by an enormous clump of dark matter rather than a supermassive black hole. Credit: AI/ScienceDaily.com Astronomers say the Milky Way may not contain a supermassive black hole at its center after all. Instead, the galaxy's core could be dominated by an enormous concentration of dark matter that produces the same powerful gravitational effects. This unseen material, which makes up most of the universe's total mass, may be able to explain two very different observations at once. Near the galaxy's center, stars move in fast, chaotic paths just light hours (often used to measure distances within our own solar system) from the core. Farther out, stars and gas rotate more smoothly across the vast outer regions of the Milky Way. The findings were published in Monthly Notices of the Royal Astronomical Society (MNRAS). Challenging the Black Hole Explanation For decades, scientists have believed that Sagittarius A* (Sgr A*) is a supermassive black hole responsible for the extreme orbits of a group of stars known as the S stars. These stars race around the galactic center at speeds reaching several thousand kilometres per second. The new study questions that interpretation. The research team pr

quantum-computingSuper-Chilled Atoms Retain Quantum Information 3.3times Longer, Boosting Computer Potential
Scientists have demonstrated significantly extended lifetimes of highly excited Rydberg atoms within a precisely controlled cryogenic environment. Junlan Jin, Yue Shi, and Youssef Aziz Alaoui, from the Department of Physics at Princeton University, alongside Jingxin Deng, Yukai Lu, and Jeff D Thompson, report achieving Rydberg state lifetimes up to s, a 3.3-fold improvement over room-temperature measurements. This advance, realised using a caesium optical tweezer array and single-photon coupling, is crucial because it directly addresses a key limitation in neutral-atom quantum computing, where Rydberg state relaxation increasingly dominates error rates. The research establishes a pathway towards higher-fidelity two-qubit gates and more complex quantum operations by minimising decoherence caused by environmental factors. This represents a 3.3(3)-fold increase compared to room-temperature measurements and signifies a substantial advancement in neutral atom quantum computing. The research demonstrates the suppression of blackbody radiation-induced transitions by enclosing the array within a 4 K radiation shield, effectively reducing the effective blackbody radiation temperature to less than 25 K. This breakthrough directly addresses a key limitation in scaling quantum computers, as relaxation of the ground-Rydberg qubit is becoming the dominant source of error in high-fidelity gate operations. The work employs single-photon coupling to coherently manipulate the ground-Rydberg qubit, circumventing issues associated with intermediate state scattering common in two-photon excitation schemes. This precise control, combined with the extended Rydberg lifetimes, pushes the system closer to the fundamental limit of spontaneous emission. Researchers constructed a bespoke ultra-high vacuum cryostat featuring a 4 K baseplate and incorporated radiation shielding at both 35 K and 4 K to minimize thermal noise. Specialized coatings were applied to windows within the shields, transmi

quantum-computingQuantum Error Fix Cuts Processing Time for Complex Problems Significantly
Scientists are increasingly focused on benchmarking noisy intermediate-scale quantum devices, and a new study details a method for data-driven evaluation of quantum annealing experiments. Juyoung Park, Junwoo Jung, and Jaewook Ahn, all from the Department of Physics at KAIST, alongside et al., present a deterministic error mitigation (DEM) procedure that improves inference from noisy measurements on Rydberg arrays. This research is significant because it establishes a framework for comparing the performance of quantum devices with classical algorithms based on both solution quality and computational cost. By applying DEM to the -independent set problem on neutral atom arrays, the team demonstrate a reduction in postprocessing overhead and predict a scaling that allows for a direct cost-based comparison between quantum experiments and their classical counterparts. These experiments often yield measurement outcomes deviating from ideal distributions, hindering accurate performance assessment. DEM is a shot-level inference procedure that leverages experimentally characterised noise to enable data-driven benchmarking, considering both solution quality and the classical computational cost of processing noisy measurements. The work demonstrates this approach using the decision version of the k-independent set problem, a computationally demanding task. Within a Hamming-shell framework, the volume of candidate solutions explored by DEM is governed by the binary entropy of the bit-flip error rate, resulting in a classical postprocessing cost directly controlled by this entropy. Experimental data reveals that DEM reduces postprocessing overhead when compared to conventional classical inference baselines. Numerical simulations and experimental results obtained from neutral atom devices validate the predicted scaling behaviour with both system size and error rate. These established scalings indicate that one hour of classical computation performed on an Intel i9 processor is eq

quantum-computingResearchers Reveal 100nm Displacement Via the Optical Magnus Effect with an Ion
Researchers have, for the first time, directly observed the optical Magnus effect in a single trapped ion, demonstrating a spin-dependent displacement of light interacting with matter. Philip Leindecker, Louis P.H. Gallagher, and Edgar Brucke, from ETH Z urich and the PSI Quantum Computing Hub, alongside colleagues including Dominique Zehnder, Luka Milanovic, and Matteo Marinelli, achieved this by spatially mapping the effect on a calcium ion using a tightly focused laser beam. This observation, revealing displacements of up to several hundred nanometres, confirms the importance of considering intrinsic longitudinal electric field components and polarization gradients when manipulating atoms with light, paving the way for more precise control in emerging technologies like optical tweezers and quantum computing. Spin-dependent atom displacement via focused light field polarisation gradients offers novel manipulation possibilities Scientists have directly observed an optical analog of the Magnus effect, revealing a spin-dependent transverse displacement of the atom-light interaction profile for a single calcium-40 ion. These displacements originate from longitudinal electric field components beyond the standard paraxial approximation, a key innovation in understanding light-atom interactions. The study employed a tightly focused Gaussian beam to induce transverse polarization gradients, which were then meticulously characterised using a phase-sensitive measurement and spatial maps for varying beam configurations. By utilising two crossed acousto-optic deflectors, the researchers achieved sub-100nm spatial resolution in positioning the laser beams, enabling precise mapping of the coupling strength for all components of the 729nm quadrupole transition from 4S1/2 to 3D5/2. Experiments revealed the spin-dependent transverse displacement of the interaction profile, stemming solely from the Gaussian beam’s intrinsic longitudinal components, confirming theoretical prediction

quantum-computingPicoseconds on Demand: Tiqker Optical Atomic Clock Cruises the Quantum Corridor
Right on Time: Bringing Picosecond Precision to Live Networks I’m excited to finally get to share that Infleqtion, together with Quantum Corridor, completed a successful live demonstration of a high-performance quantum timing solution for critical networked infrastructure. We ran the test across 22 kilometers of live urban fiber, between Chicago’s ORD10 Data Center and the Digital Crossroad Data Center in Hammond, Indiana and back. Tiqker, Infleqtion’s 3U rack-mounted optical atomic clock, empowered with the White Rabbit time transfer protocol, held picosecond-level synchronization. The system outperformed traditional rack references and GPS-derived time on the short-to-medium timescales that matter for modern network data systems. Figure 1: Tiqker installation in Hammond, Indiana This matters because the future depends on timing that actually matches how fast hardware performs. What we showed is that deterministic, picosecond-class timing can be delivered over existing fiber in real conditions, aligning timing precision with the physical timescales of contemporary optical network hardware. We ran the test in the real world – these aren’t lab numbers. Figure 2: Tiqker units, White Rabbit switches and time distribution installed at Digital Crossroads. Where Timing Is Everything The potential applications for Tiqker optical atomic clocks are wide-ranging. In data centers and distributed computing, picosecond timing enables precise packet alignment, cutting time buffers and improving throughput. Emerging telecommunications systems using time-sensitive networking require deterministic time, while financial customers gain more accurate timestamps for trading, audit, and model training data.
