Computer scientists say they’ve cracked the science behind error-correction in quantum computers thanks to new "4D codes." Developed by Microsoft, the new codes were revealed in a blog post published June 19 and purport to address the problem of fault tolerance — arguably quantum computing’s biggest bottleneck. All computers can produce errors. In classical computing, error correction is achieved by making multiple copies of every bit of information that’s sent. If one or more bits are lost or corrupted, the remaining bits still contain the original information.

Qubits, however, can’t be copied. They also cannot be measured without experiencing what’s called "collapse." This makes it much more challenging to detect and mitigate errors (which occur at a significantly higher rate than in classical bits) as they... Advancements in error correction can lead to more reliable quantum computation. Microsoft’s quantum team announced Thursday that it has made advancements in its quantum compute platform that addresses a large issue in quantum computing: error correction. The team said it has developed a family of “novel four-dimensional" error correction codes that are “applicable to many types of qubits,” the team said in a blog post. A qubit, or quantum bit, is “the basic unit of information used to encode data in quantum computing and can be best understood as the quantum equivalent of the traditional bit used by classical...

Because the novel codes require very few physical qubits per logical qubit, they can “check for errors in a single shot and exhibit a 1,000-fold reduction in error rates,” the Microsoft team said.

In a quiet revolution that may reshape the foundation of quantum computing, scientists have solved a key problem in quantum error correction that was once thought to be fundamentally unsolvable. The breakthrough centers on decoding—the process of identifying and correcting errors in fragile quantum systems—and could accelerate our path toward practical, fault-tolerant quantum computers. The team, led by researchers from the Singapore University of Technology and Design, the Chinese Academy of Sciences, and the Beijing Academy of Quantum Information Sciences (BAQIS), has developed a new algorithm known as... This isn’t just a modest improvement—PLANAR achieved a 25% reduction in logical error rates when applied to Google Quantum AI’s experimental data, rewriting what experts thought they knew about hardware limits.

What makes this achievement so significant is that it challenges a long-standing assumption in the field: that a portion of errors—called the “error floor”—was intrinsic to the hardware. Instead, PLANAR reveals that a quarter of those errors were algorithmic, not physical, caused by limitations in the decoding methods rather than the quantum devices themselves. This insight not only breathes new hope into the quest for scalable quantum computing—it redefines what we thought was possible. Microsoft scientists developed a 4D geometric coding method that reduces errors 1,000-fold in quantum computers.

Quantum computing breakthrough could make 'noise' — forces that disrupt calculations — a thing of the past, however, can’t be copied. They also cannot be measured without experiencing what’s called"collapse." This makes it much more challenging to detect and mitigate errors to the operational space via entanglement. It works in four dimensions using a mathematical expression that, essentially, allows entanglement points to make connections over the surface of a"torus," which can be imagined as a donut shape.in the past, their use... By"twisting" the geometry, the 4D code overlay creates a larger representational space that reflects a greater portion of the quantum state of the actual qubits in use. Doing so allows researchers to detect errors in the code without disturbing the actual quantum processes occurring within the system.

The researchers ran their new “twisted” code on existing quantum computers and experimentally confirmed their theories in a separate preprint paper, "Universal fault-tolerant quantum computers may be realized using 4D geometric codes, which are... Furthermore, the researchers purportedly demonstrated a groundbreaking technique for"replacing" the atoms used as qubits when they’re lost. In certain quantum computing systems, qubits are created by snagging neutral atoms with laser tweezers and trapping them in place. During computations, these atoms can be lost or dropped.The researchers say they could replace lost atoms mid-cycle using an atomic beam to force new atoms into the array without disrupting the calculations — a...

Credit: Institute of Science Tokyo, Japan A new class of highly efficient and scalable quantum low-density parity-check error correction codes, capable of performance approaching the theoretical hashing bound, has been developed by scientists at Institute of Science Tokyo, Japan. These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields, including quantum chemistry and optimization problems.

In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications targeted by quantum computers, such as quantum chemistry, cryptography, etc., demand millions or even more logical qubits. Scaling to such numbers is a major challenge, as quantum computers suffer from inherent errors that increase rapidly with the number of qubits. For practical quantum computing, highly efficient quantum correction methods that can accommodate a vast number of logical qubits are necessary. Unfortunately, current quantum error correction methods are extremely resource-intensive, relying on essentially zero-rate codes. As a result, only a tiny fraction of reliable logical qubits can be extracted from an overwhelmingly large number of physical qubits.
