The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...

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 ...

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 ...

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

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 ...

Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely on qubits (i.e., the quantum equivalent of bits), which can store ...

A new technical paper titled “Leveraging Qubit Loss Detection in Fault-Tolerant Quantum Algorithms” was published by researchers at MIT, Harvard and QuEra Computing. “Qubit loss errors constitute a ...

Algorithms called phantom codes could help quantum computers run complex programs without errors, overcoming a big hurdle for making the technology more broadly useful. Many popular error-correcting ...

Quantum is smart. The progression toward embryonic quantum computing services represents a shift (you know what kind) in terms of the amount of intelligence we can apply to computing, data analytics ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...
