Optimized EIT-Based Multi-Target CNOT^k Gates in Heteronuclear Rydberg Atom Arrays

--> Quantum Physics arXiv:2608.15033 (quant-ph) [Submitted on 15 Aug 2026] Title:Optimized EIT-Based Multi-Target CNOT^k Gates in Heteronuclear Rydberg Atom Arrays Authors:Zeyu Zhou, Xian-Lei Sheng, Peng Xu, Jian Cui View a PDF of the paper titled Optimized EIT-Based Multi-Target CNOT^k Gates in Heteronuclear Rydberg Atom Arrays, by Zeyu Zhou and 3 other authors View PDF HTML (experimental) Abstract:Efficient stabilizer readout requiring multi-qubit coupling is a core bottleneck for quantum error correction. One feasible method is direct implementation of the controlled-U gate between one ancilla qubit and the data qubits assigned to stabilizer U measurements. We systematically analyze the native multi-target $\mathrm{C}^1\mathrm{NOT}^k$ gates proposed by Müller et al., which is realized via electromagnetically induced transparency (EIT) and Rydberg blockade mechanisms. Using a microscopic open-system model, we analyze the gate's scaling with target number k and identify spontaneous emission, Doppler dephasing, target atom inter-coupling, and technical noise as major error contributions. We further optimize the protocol combining two-photon STIRAP control, heteronuclear interaction engineering, and waveform optimization. Our optimized heteronuclear protocol reaches fidelities of 98.03% ($\mathrm{C}^1\mathrm{NOT}^{1}$) and 96.54% ($\mathrm{C}^1\mathrm{NOT}^{4}$), in the presence of all primary noise sources and realistic experimental parameters. These results demonstrate that EIT-based multi-target gates serve as a practical building block for low-depth stabilizer readout.

Ytterbium atoms unlock quantum boost to 60-second magnetic coherencequantum-computing

Ytterbium atoms unlock quantum boost to 60-second magnetic coherence

Researchers affiliated with the Hefei National Research Center for Physical Sciences at the Microscale and the University of Science and Technology of China have achieved a spin coherence time of 60 seconds using ytterbium atoms, a duration that significantly exceeds typical cold-atom systems and promises more sensitive magnetic field sensors. The comagnetometer utilizes both isotopes of ytterbium, 171Yb (spin-1/2) and 173Yb (spin-5/2), jointly trapped within an optical lattice occupying approximately 160 lattice sites; vector and tensor light shifts are suppressed through polarization control and a Schrödinger cat state, respectively. This setup enables simultaneous Ramsey interferometry on both isotopes and achieves a magnetic noise suppression factor exceeding 3 x 10^4, while determining the ratio of nuclear magnetic moments to 4 parts per million precision. The results establish a new platform for spin-based sensing and may open pathways toward quantum-enhanced searches for physics beyond the Standard Model. Ytterbium Isotopes Enable Long-Coherence Comagnetometry A spin coherence time of 60 seconds achieved using ytterbium atoms represents a considerable advancement in cold-atom comagnetometry and promises enhanced sensitivity for magnetic field sensors. Researchers affiliated with the Hefei National Research Center for Physical Sciences at the Microscale and the University of Science and Technology of China in Hefei demonstrated this extended coherence by jointly trapping the isotopes ytterbium-171 and ytterbium-173 within an optical lattice, a configuration that suppresses magnetic noise and enables precise measurements. This achievement surpasses typical cold-atom coherence times. The team’s approach specifically addresses decoherence induced by light shifts, a common obstacle in utilizing cold atoms for precision measurements. The comagnetometer’s design relies on the distinct spin properties of the two ytterbium isotopes; 171Yb possesses a spin of 1/2, whil

Shanxi University Team Simulates 9999 Fidelity CZ Gatequantum-computing

Shanxi University Team Simulates 9999 Fidelity CZ Gate

Until now, achieving high-fidelity controlled-Z (CZ) gates for Rydberg atoms has been limited by level-crossing issues and susceptibility to noise during quantum operations. Now, researchers at Shanxi University have designed a new CZ gate scheme achieving a fidelity of 0.9999. This advance utilises level-crossing-free echoing rapid adiabatic population transfer with specifically shaped laser pulses, maintaining a fidelity above 0.999 even with fluctuations in laser power and frequency of up to ±2% and ±1% respectively. This new method employs specifically shaped laser pulses to manipulate atoms without encountering problematic level-crossing points, which typically cause errors in quantum operations. The design also maintains high accuracy even with small variations in laser power and frequency, crucial for building stable quantum systems. This breakthrough centres on a new method for manipulating these atoms, employing precisely shaped laser pulses to enact a ‘controlled-Z’ gate, a fundamental operation in quantum computing akin to an ‘and’ gate in classical systems. The team’s design avoids problematic level-crossing points, moments where errors typically occur, by utilising a technique called rapid adiabatic population transfer, ensuring stable and reliable operations. Like tiny switches, Rydberg atoms are exceptionally sensitive and can be precisely controlled with lasers, but maintaining this control amidst real-world imperfections has been a challenge. The researchers also modelled how quantum systems lose energy, similar to accounting for friction in a mechanical system, to further refine their approach. Rydberg atom gate surpasses fidelity thresholds using strong laser pulse control Error rates for two-qubit controlled-Z (CZ) gates dropped to 0.9999, a sharp improvement over previous benchmarks. This represents a threshold for practical quantum computation, exceeding the capabilities of earlier methods limited by susceptibility to noise and level-crossing i

Shots-to-Approximate-Solution Scaling in Neutral-Atom Quantum Optimization

Here, we introduce a shots-to-approximate-solution metric, STS(r), where r denotes the approximation ratio, and evaluate it using postprocessed outputs modeled by a degeneracy-weighted shell distribution governed by a single effective parameter, $\beta$, that quantifies concentration toward near-optimal independent sets. To extract the genuine concentration effect in the quantum data, we apply identical postprocessing to both experimental bitstrings and randomly generated bitstrings with matched excitation density, thereby constructing an excitation-matched random baseline. Experiments on programmable Rydberg-atom arrays with system sizes up to 125 sites show that quantum annealing consistently exceeds the random baseline, demonstrating enhanced concentration toward low-energy solution structure beyond what can be attributed solely to excitation density. The results further reveal two distinct target-dependent regimes. For near-exact targets with $r \approx 1$, the required shot count grows exponentially with system size and is reduced at the same exponential level by quantum annealing within the shell-model description. By contrast, for relaxed targets, the shot cost becomes effectively constant, and the corresponding quantum enhancement diminishes, with the classical postprocessing heuristic alone reaching the target in order-unity attempts. Together, these results establish an operational method for quantifying quantum optimization performance and clarify the reg

Robust topological quantum state transfer with long-range interactions in Rydberg arraysquantum-computing

Robust topological quantum state transfer with long-range interactions in Rydberg arrays

AbstractWe develop a theoretical framework for fast, robust and high-fidelity topological quantum state transfer in one-dimensional systems with long-range couplings, motivated by chains of Rydberg atoms with dipole–dipole interactions. Such long-range interactions naturally give rise to extended Su–Schrieffer–Heeger and Rice–Mele models supporting topologically protected edge states. We show that these edge states enable high-fidelity edge-to-edge excitation transfer using both time-independent protocols, based on coherent edge state dynamics, and time-dependent protocols, based on adiabatic modulation of system parameters. Long-range couplings play a central role by enhancing the relevant energy gaps, leading to a substantial improvement in transfer efficiency compared to nearest neighbour models. The resulting transfer is robust against positional disorder, reflecting its topological origin and highlighting the potential of long-range interacting platforms for reliable quantum state transfer.Featured image: Quantum state transfer in the extended Rice-Mele model. a)-e) Rydberg excitation probability distribution and lattice configuration at representative times during an edge-to-edge quantum state transfer protocol in the extended Rice–Mele model.

Infleqtion’s sales jumped 116% as quantum deals grow

Infleqtion reported $12.6 million in second quarter revenue, a 116% year-over-year increase driven by its quantum business. This growth coincides with a Letter of Intent from the Commerce Department for up to $100 million in proposed funding, which validates the company’s technology and roadmap. “Q2 was a record quarter for Infleqtion, and the pace of quantum commercialization is accelerating,” said Chief Executive Officer Matt Kinsella, as the firm remains on track to achieve 30 logical qubits by year’s end and plans a new Illinois quantum computer capable of scaling beyond 50 logical qubits. 116% Revenue Growth Fuels Infleqtion’s Quantum Commercialization Infleqtion’s second quarter revenue reached $12.6 million, a 116% increase compared to the same period last year, demonstrating substantial growth fueled by its quantum business. This surge in earnings signals a shift from research and development toward practical applications of quantum technologies, a trend the company attributes to rising government investment and increasing customer demand. Unlike many firms in the quantum sector, Infleqtion reports this growth as fully organic, stemming from internal development and sales rather than acquisitions or partnerships. The company’s financial health is further bolstered by a strong balance sheet, ending the quarter with $582 million in cash and marketable securities, and no debt. A temporary benefit of $27.4 million from payroll taxes related to stock-option exercises contributed to operating cash flow, though Infleqtion anticipates remitting these funds in the third quarter. This financial stability positions Infleqtion to capitalize on a recent Letter of Intent from the U.S. Department of Commerce, which also contemplates the department receiving Infleqtion common stock, pending final agreements and government approvals. Looking ahead, Infleqtion has raised its full-year revenue outlook to approximately $43 million and remains on track to achieve its goal of 30

Pasqal and Swiss Quantum Initiative sponsor CERN’s quantum skills training

Thirty-four students from over 30 nationalities recently converged at CERN for the Quantum Materials Hackathon, applying quantum computing to challenges similar to those faced by large-scale scientific infrastructure. The event, hosted by CERN and the Open Quantum Institute, tasked participants with solving real-world problems using quantum hardware and simulators, guided by experts from both industry and research. Quantum materials were the focus, given their critical role in technologies like the superconducting magnets and sensors essential to CERN’s particle accelerators. “Quantum hackathons allow students to apply quantum computing to solve real-world problems,” said Julia Thiele, an Open Quantum Initiative Advisory Committee member, emphasizing the need for a skilled workforce to utilize increasingly accessible quantum resources. Participants moved beyond theoretical exercises, directly applying quantum computing resources to challenges proposed by industry and research partners; this hands-on approach distinguishes the event from more conventional academic training. Each team tackled a specific problem, receiving mentorship throughout the process from experts at organizations like Pasqal and the University of Geneva, fostering a direct link between emerging talent and established quantum technology developers. Funding for the hackathon came from both Pasqal and the Swiss Quantum Initiative, demonstrating investment in practical quantum education beyond basic research. The selection of quantum materials as the central focus reflects CERN’s own reliance on these technologies; superconducting magnets and advanced sensors integral to the laboratory’s particle accelerators depend on their unique properties, suggesting a strategic alignment between skills development and infrastructure improvement.
