The physical realization of a quantum computer requires built-in error-correcting codes that compensate the disruption of quantum information arising from noise. Here, the authors demonstrate a ...

First Layer: Quantum Code—The Underlying Programming Language of the Universe To understand how the classical world emerges, ...

According to Shalby, the most widely used error correction technique is called the surface code, and a “surface code chip” is a quantum processor designed around this method. He said such chips can ...

Recently, a research team from the University of Sheffield proposed an innovative quantum error correction protocol that effectively corrects common single-qubit insertion errors in quantum computing.

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP ...

UC Riverside researchers show scalable quantum systems are possible with noisy chip links, defying hardware limits.

A library of computer code developed for quantum interactions can be used on problems from modeling the flow of electrons to predicting the price of copper in a stock market. (Illustration: Purdue ...

Keqin Feng, Chaoping Xing, A New Construction of Quantum Error-Correcting Codes, Transactions of the American Mathematical Society, Vol. 360, No. 4 (Apr., 2008), pp. 2007-2019 ...

The paper has triggered a wave of activity in the quantum gravity community, and new quantum error-correcting codes have been discovered that capture more properties of space-time.

A future in which quantum computers are commonplace might seem like an optimistic fantasy, but it could also involve hackers using those computers to steal important information. To thwart would-be ...

The practical assessment of quantum computing by tech leaders requires knowledge of how quantum computing differs from classical computing systems.
