Overview of Quantum Day 2026 and Platform Launch
On July 9, 2026, Logical Qubit Technology Co., Ltd hosted its Quantum Day 2026 event and unveiled a superconducting quantum‑computing cloud platform. The platform is designed to serve universities, research institutions, and industries such as biomedicine, chemistry, materials, energy, AI, finance, and logistics. By offering remote access to high‑performance quantum hardware, logical‑qubit research tools, and pulse‑level control, the company aims to lower the barrier to quantum adoption and accelerate integration of quantum computing into real‑world applications.
Physical Qubit Level: Hardware Performance
The cloud platform’s foundation lies in its superconducting‑qubit hardware. Users can execute arbitrary single‑qubit gates in just 20 nanoseconds, achieving a maximum fidelity of 99.97 %. Two‑qubit gates are completed in 40 nanoseconds with a fidelity up to 99.8 %. Importantly, operation time does not scale with qubit count; parallel control of over 100 qubits remains in the tens‑of‑nanosecond range. The AGate‑100 chip, which powers the platform, features frequency‑tunable physical qubits linked by tunable couplers. Median performance metrics include parallel single‑qubit gate fidelity of 99.93 %, parallel two‑qubit gate fidelity of 99.5 %, and parallel readout fidelity of 98.6 %, figures that meet or exceed those of leading international quantum cloud services. For academic and industrial R&D teams, submitting quantum algorithms as code to the cloud yields immediate circuit translation and result retrieval, dramatically simplifying workflow.
Logical Qubit Level: Error‑Corrected Computing
Logical qubits, constructed from multiple physical qubits, are essential for fault‑tolerant quantum computation. Logical Qubit Technology has advanced this layer by reducing qubit readout time from 2 microseconds to approximately 600 nanoseconds on its AGate‑165 chip, with reset after each readout shortened to 400 nanoseconds. The platform now supplies distance‑9 repetition code and distance‑3 surface‑code algorithms, enabling users to run and verify error‑correction and decoding protocols. Median fidelities for these logical‑qubit operations mirror the physical‑qubit levels: parallel single‑qubit gate fidelity of 99.93 %, parallel two‑qubit gate fidelity of 99.5 %, and parallel readout fidelity of 98.7 %. These capabilities bring the community closer to achieving exponentially suppressed logical error rates as qubit numbers increase.
Pulse‑level Control Level: Waveform Precision
While quantum circuits provide a universal programming interface, actual execution on superconducting chips depends on precise physical waveforms—square, Gaussian, and continuous sine pulses applied to qubits and couplers. The cloud platform now grants pulse‑level control, allowing users to modify arbitrary waveforms with timing precision down to 1 nanosecond. This fine‑grained manipulation enables optimized gate shapes, higher fidelities, and more efficient control strategies. Researchers thus gain laboratory‑grade control over the underlying hardware without maintaining cryogenic equipment or pulse‑generation systems, effectively turning the cloud service into a remote quantum‑computing lab.
Fostering Quantum Computing Ecosystem Collaboration
Logical Qubit Technology views the cloud platform as a catalyst for a broader quantum ecosystem. At Quantum Day 2026, CEO Zhen Wang highlighted collaborations with pharmaceutical partner Pharmaron and software algorithm firms Liangguan Zhiyuan, Quantum Emergence, Tongyuan Liangzhi, and UnitaryForge. The strategic cooperation agreement with Pharmaron aims to create joint laboratories and explore models that move the pharmaceutical industry toward a “Quantum‑ready” state—aligning R&D processes, technical standards, and data frameworks with quantum capabilities. By uniting hardware providers, algorithm developers, and end‑users, the company seeks to nurture a thriving ecosystem where quantum computing delivers tangible social and economic value.
Impact on Target Industries
The platform’s accessibility opens doors for sectors traditionally limited by the cost and expertise required for quantum hardware. In biomedicine, quantum simulations could accelerate drug‑discovery pipelines by modeling complex molecular interactions. Chemistry and materials science stand to benefit from accurate prediction of reaction pathways and novel material properties. Energy applications may include optimization of grid distribution and catalyst design. AI, finance, and logistics can exploit quantum advantage in optimization, machine‑learning acceleration, and risk modeling. By providing a low‑entry‑point cloud service, Logical Qubit Technology aims to catalyze cross‑disciplinary innovation and demonstrate quantum superiority in practical problem‑solving.
Coherence Time Progress and Future Hardware Goals
Coherence time remains a pivotal metric for superconducting qubits. Over nearly two decades, the field has improved coherence from roughly 1 microsecond to the millisecond range—a three‑order‑of‑magnitude gain. Logical Qubit Technology has recently achieved over 890 microseconds of coherence on a small‑scale chip. The next step is to transfer this enhanced coherence to its hundred‑qubit AGate devices, thereby improving physical‑qubit manipulation fidelity, suppressing logical error rates, and sustaining momentum toward universal quantum computing. Continued advances in coherence will directly benefit all layers of the platform—physical, logical, and pulse‑control—by enabling longer, more reliable quantum circuits.
Roadmap 2026‑2030+
Logical Qubit Technology follows a dual‑driven “Technology + Applications” strategy. The roadmap outlines clear milestones:
- 2026: Launch the quantum cloud platform with physical‑qubit, logical‑qubit, and pulse‑level control capabilities; stimulate ecosystem growth.
- 2027: Surpass the fault‑tolerance threshold, delivering modular logical qubits with error rates of 10⁻³ (one in a thousand).
- 2028: Achieve deep integration with drug discovery, materials simulation, AI, and related fields, producing results that outperform classical computers.
- 2029: Engineer tens of thousands of physical qubits, realize dozens of logical qubits, and push error rates down to 10⁻⁸ (one in a hundred million).
- Beyond 2030: As the technology and ecosystem mature, deploy universal quantum algorithms on general‑purpose quantum computers, extending the limits of human computational capacity.
Each stage balances hardware breakthroughs with validated application scenarios, ensuring that technical progress translates lab advances into industry impact, and guides investment toward scalable, useful quantum computing.
Naming, Vision, and Closing Invitation
The company’s chip series bears the name AGate. As founder and CEO Zhen Wang explained, “AGate” literally translates to “agate,” reflecting the crystalline nature of the devices forged through meticulous micro‑nanofabrication. Deconstructed, “A Gate” signifies “a door”—the aspiration that each AGate chip opens a doorway to the future of quantum computing.
