Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are practically impossible to solve. Quantum computers threaten to flip that ...

Their framework, outlined in a paper published in Nature Physics, specifically proposes the construction of quantum codes that are defined on spheres. "In graduate school, I was part of a team of ...

Schematic of crystal structure of iron-telluride thin film grown on a cadmium telluride substrate, where lattice matching is achieved in groups of atoms. If quantum computing is going to become an ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

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, ...

High-rate quantum error correcting (QEC) codes with moderate overheads in qubit number and control complexity are highly desirable for achieving fault-tolerant ...

IQM Quantum Computers has developed a new quantum error-correcting code that it says can reduce logical error rates by up to 1,000 times compared with the widely used ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

In this paper, we prove a lower bound on the soundness of quantum locally testable codes under the distance balancing construction of Evra et al. Our technical contribution is that the soundness of ...
