Quantum computing news usually picks up near the end of the year, as companies try to provide evidence that they are hitting ...

A team of U.S. researchers has designed a passive quantum error correction technique that enables qubits to correct their own ...

for error-corrected surface code logical qubits 3,4,13. Here d is the code distance indicating 2d 2 − 1 physical qubits used per logical qubit; p and ε d are the ...

Quantum cat states built from intrinsically nonclassical components have been demonstrated by Oxford physicists in a trapped ...

Without quantum error correction, it would be impossible for quantum computers to outperform their classical counterparts, and thus efforts to advance this technology are ongoing worldwide.

Quantum simulations of lattice gauge theories (LGTs) are often formulated on an enlarged Hilbert space containing both physical and unphysical sectors in order to retain a local Hamiltonian. We ...

Schematics of EFBQC. In a fusion network, the photons participating in fusions are encoded in a QEC code, and an encoded-fusion protocol is performed actively in a concatenative manner between encoded ...

Universal fault-tolerant quantum computing relies on the implementation of quantum error correction. An essential milestone is the achievement of error-corrected ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...
