The results show that, using only the nearest-neighbour iSWAP gates already native to IQM's Crystal processors, directional ...

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 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 ...

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

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 ...

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

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 ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...

When running a server, especially one with mission-critical applications, it’s common practice to use error-correcting code (ECC) memory. As the name suggests, it uses an error-correcting algorithm to ...

Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine. In 1994, Peter Shor, a ...
