Logical Qubit Technology launches cloud platform

Logical Qubit Technology Co., Ltd. announced the launch of its new superconducting quantum computing cloud platform at Quantum Day 2026 on July 9, 2026. The platform provides universities, research institutions, and various industries with access to high-performance quantum computing services, specifically targeting areas such as biomedicine, chemistry, materials science, energy, artificial intelligence, finance, and logistics.

The development of quantum computing faces significant hurdles. These include the need for technological advancements and improved engineering to increase qubit counts, extend coherence times, and enhance two-qubit gate fidelities. Another challenge is the high entry barrier for users due to the substantial cost of quantum computer systems and the limited availability of practical quantum cloud computing power. Logical Qubit Technology aims to address these issues by making quantum computing more accessible and fostering its integration across industries.

Advancing Quantum Capabilities with Cloud Services

Logical Qubit Technology’s new quantum cloud platform is a strategic answer to the challenges facing quantum computing adoption. The company plans to lower user barriers and accelerate the integration of quantum technology into various industries. This initiative aims to broaden the application of quantum computing and make its capabilities more widely available to a diverse user base.

Zhen Wang, founder and CEO of Logical Qubit Technology, introduced the platform’s key technical capabilities during Quantum Day 2026. These capabilities span three critical levels: physical qubits, logical qubits, and pulse-level control, each designed to provide comprehensive support for quantum research and application development. The platform represents a concerted effort to push quantum computing toward practical utility.

Physical Qubit Performance

The cloud platform’s quantum circuit execution relies on high-performance underlying quantum hardware. This superconducting-qubit-based system merges rapid operation speeds with high fidelity. Users can execute single-qubit gates in just 20 nanoseconds, achieving a maximum single-qubit gate fidelity of 99.97 percent. Two-qubit gates execute in 40 nanoseconds with a maximum fidelity of 99.8 percent.

Notably, the operation time remains constant regardless of the number of qubits, allowing parallel control of over 100 qubits in mere tens of nanoseconds. Logical Qubit Technology supports quantum circuit execution with its 30-qubit and 100-qubit AGate series chips. The AGate-100 chip, available on the platform, features frequency-tunable physical qubits connected by tunable couplers. It achieves a median parallel single-qubit gate fidelity of 99.93 percent, a median parallel two-qubit gate fidelity of 99.5 percent, and a median parallel readout fidelity of 98.6 percent. These metrics align with or surpass those of other prominent international quantum cloud platforms.

The platform provides a significant resource for researchers in academia and industrial R&D. A cloud platform with over 100 physical qubits meets the daily demands for quantum computing and algorithm research. Users simply submit their algorithms as code, and the platform translates them into quantum circuits and returns execution results, simplifying the process and lowering adoption barriers.

Logical Qubit Implementation

Logical qubits represent the core building blocks for universal quantum computing, constructed from multiple physical qubits. Achieving fault tolerance in quantum computing requires fast qubit readout for error detection during circuit execution. When physical qubit gate fidelity surpasses a certain threshold, the error rate of logical qubits decreases exponentially as the number of physical qubits increases.

To meet these demands, Logical Qubit Technology developed the AGate-165 superconducting quantum chip. This chip reduces readout time from 2 microseconds to approximately 600 nanoseconds, with a reset time after each readout shortened to 400 nanoseconds. The Logical Qubit Technology quantum cloud platform now offers distance-9 repetition code and distance-3 surface code algorithms. These algorithms demonstrate a median parallel single-qubit gate fidelity of 99.93 percent, a median parallel two-qubit gate fidelity of 99.5 percent, and a median parallel readout fidelity of 98.7 percent. This allows quantum algorithm researchers to run and verify theoretical effects, such as error correction and decoding algorithms, directly on the platform.

Pulse-Level Control

Quantum circuits operate as the “common programming language” for quantum computers, allowing most customers to implement arbitrary quantum algorithms using single-qubit gates, two-qubit gates, and readout operations. On superconducting qubit platforms, however, actual execution relies on a “machine language” of physical waveforms, including square waves, Gaussian pulses, and continuous sine waves. For advanced users, direct manipulation of these physical waveforms applied to each qubit and coupler is essential for achieving higher fidelity and more efficient control.

The Logical Qubit Technology quantum cloud platform now offers access to quantum computers with pulse-level control. This feature allows users to directly modify arbitrary waveforms with timing precision down to 1 nanosecond. Customizing complex pulse-level control enables users to achieve optimized and more sophisticated quantum manipulations. These capabilities grant users laboratory-level underlying control through online access, enabling them to run a “quantum computing lab” without the burden of maintaining hardware.

Building a Collaborative Quantum Ecosystem

The year 2025 is often considered a breakout year for quantum computing, while 2026 is poised to be when the quantum computing ecosystem truly flourishes. Industries such as pharmaceuticals, chemicals, materials, energy, artificial intelligence, and finance are beginning to integrate quantum computing into their operations. Simultaneously, a growing number of software and algorithm companies have emerged, significantly enriching the quantum computing ecosystem.

At the Quantum Day 2026 event, Zhen Wang highlighted the progress made by partners leveraging the Logical Qubit Technology cloud platform. These partners include pharmaceutical company Pharmaron, and software algorithm companies Liangguan Zhiyuan, Quantum Emergence, Tongyuan Liangzhi, and UnitaryForge. Logical Qubit Technology has also established a strategic cooperation agreement with Pharmaron. This partnership explores collaborative models between quantum cloud platforms and pharmaceutical companies through joint laboratories and other initiatives, aiming to transition the pharmaceutical industry’s R&D systems, technical standards, and data frameworks toward a “Quantum-ready” state, driving innovation within the sector.

Zhen Wang emphasized the collective effort required: “Although quantum computing is still in its early stages, we hope to work with these partners and many more in the future to foster a thriving quantum computing ecosystem, enabling quantum computing to truly deliver value and create social impact.” At this stage, technology remains the top priority for quantum computing development, and coherence time is one of the most critical technical metrics for superconducting quantum chips. Wang noted the nearly two decades of superconducting quantum computing development, during which coherence time has improved by three orders of magnitude, from 1 microsecond to the millisecond range. Logical Qubit Technology actively works to extend coherence time, recently achieving over 890 microseconds on a small-scale chip. The company plans to transfer this technology to hundred-qubit quantum chips, further enhancing physical qubit manipulation fidelity and reducing logical qubit error rates, providing sustained technological momentum toward universal quantum computing.

Roadmap for Quantum Computing Development

Quantum computing represents a challenging yet promising direction. A structured roadmap with clear milestones is crucial, balancing technological advancements with practical applications. Logical Qubit Technology operates with a dual-driven strategy, prioritizing “Technology + Applications.” This approach involves continuously improving technical capabilities for future universal quantum computing while iteratively enhancing technology through validated commercial application scenarios.

The company’s roadmap includes several key milestones. In 2026, Logical Qubit Technology launched its quantum cloud platform, integrating physical qubits, logical qubits, and pulse-level control, designed to spur ecosystem growth. By 2027, the company aims to break through the “fault-tolerance threshold,” achieving modular logical qubits with error rates of one in a thousand (10⁻³). In 2028, the objective is to achieve deep integration with drug discovery, materials simulation, and artificial intelligence, producing milestone results that surpass classical computers.

Looking further ahead to 2029, the company plans to move toward large-scale quantum computing. This involves completing the engineering of tens of thousands of physical qubits, realizing dozens of logical qubits, and achieving an error rate of one in a hundred million (10⁻⁸). Beyond 2030, as quantum computing technology and its ecosystem mature, the goal is to implement a wide range of universal quantum algorithms on general-purpose quantum computers, pushing beyond the current limits of human computational capability.

Zhen Wang explained the naming of their chip series: “We named our chip series AGate. The word literally translates to ‘agate’—because our chips are essentially crystals that require meticulous crafting through micro-nanofabrication and precision control. But broken down, ‘A Gate’ means ‘a door.’ With the AGate series of quantum chips, we hope to open a door to the future.” This name encapsulates the company’s vision and dedication to advancing quantum technology.
