Breakthrough in Quantum Computing: Photonic’s New QLDPC Codes Reduce Physical Qubit Requirements by 20x

In a leap towards practical quantum computing, Photonic Inc. has unveiled a new family of Quantum Low-Density Parity Check (QLDPC) codes that can efficiently perform both computation and error correction using fewer quantum bits (qubits) than traditional surface code approaches. This breakthrough work, detailed in the paper “Computing Efficiently in QLDPC Codes,” promises to accelerate the timeline for helpful quantum computing by up to 20 times.

The new codes, named SHYPS codes, offer efficiency gains of up to 20 times compared to traditional approaches to error correction, potentially reducing the need for millions of physical qubits in large-scale systems. Quantum computers require error correction to realize their full potential, and this development marks a significant step toward that goal.

The fast and lean QLDPC code family has specific hardware requirements, such as high levels of connectivity, which Photonic’s Entanglement First architecture can deliver. The codes have been rigorously tested in the most complete simulations known to date, demonstrating their practicality. They are also designed to work within and between modules, making them suitable for distributed systems.

For more information about the SHYPS QLDPC code family and Photonic’s advances in efficient quantum error correction, readers can access the papers “Launching SHYPS: QLDPC is the New Error Correction” and “Computing Efficiently in QLDPC Codes” on Photonic’s website.

Founded in 2018, Photonic Inc. is a leading quantum company developing commercial-scale quantum computers and quantum networks to address some of the world’s most pressing challenges across various sectors. The company’s Entanglement First architecture leverages optically linked silicon spin qubits with high connectivity, enabling entanglement distribution for robust computation, efficient error correction, and seamless integration into existing data center and telecom environments. Headquartered in Vancouver, British Columbia, Photonic has over 150 employees and is backed by leading investors and multinational partners.

The new QLDPC code family, SHYPS, is fast, lean, and patent-pending. It has specific hardware requirements that not every approach to quantum computing can deliver. Photonic’s Entanglement First architecture provides the high levels of connectivity needed to realize the benefits of QLDPC codes.

The SHYPS codes have been stress-tested in the most complete simulations, demonstrating that the logic works in practice, not just in theory. Moreover, this approach is implementable on distributed systems, working both within and between modules.

David Shaw, Lead Analyst at Global Quantum Intelligence, commented, “We’re going to see a race between players that invest in the scarce skills required for in-house code innovation, and those that seek to be fast followers.” He added, “Implementing logic always looked like the hard part of standing-up better codes. This new work has knocked it out of the park.”

As the Official Quantum Dog (or hound) by role is to dig out the latest nuggets of quantum goodness. There is so much happening right now in the field of technology, whether AI or the march of robots. But Quantum occupies a special space. Quite literally a special space. A Hilbert space infact, haha! Here I try to provide some of the news that might be considered breaking news in the Quantum Computing space.
