Constructions of k-uniform and absolutely maximally entangled states beyond maximum distance codes

Physical Review Research, 2020
Pure multipartite quantum states of n parties and local dimension q are called k-uniform if all reductions to k parties are maximally mixed. These states are relevant for our understanding of multipartite entanglement, quantum information protocols, and ...

Simple quantum error-correcting codes [PDF]

Physical Review A, 1996
Methods of finding good quantum error correcting codes are discussed, and many example codes are presented. The recipe C_2^{\perp} \subseteq C_1, where C_1 and C_2 are classical codes, is used to obtain codes for up to 16 information qubits with correction of small numbers of errors. The results are tabulated.

Quantum memory at nonzero temperature in a thermodynamically trivial system

Nature Communications
Passive error correction protects logical information forever (in the thermodynamic limit) by updating the system based only on local information and few-body interactions. A paradigmatic example is the classical two-dimensional Ising model: a Metropolis-

Approximate Quantum Error Correction with 1D Log-Depth Circuits

PRX Quantum
Efficient and high-performance quantum error correction is essential for achieving fault-tolerant quantum computing. Low-depth random circuits offer a promising approach to identifying effective and practical encoding strategies.

Multiqubit Rydberg Gates for Quantum Error Correction

PRX Quantum
Multiqubit gates that involve three or more qubits are usually thought to be of little significance for fault-tolerant quantum error correction because single gate faults can lead to errors of high Pauli weight.

Probabilities of Failure for Quantum Error Correction [PDF]

Quantum Information Processing, 2005
We investigate the performance of a quantum error-correcting code when pushed beyond its intended capacity to protect information against errors, presenting formulae for the probability of failure when the errors affect more qudits than that specified by the code's minimum distance.

Hardware-efficient autonomous error correction with linear couplers in superconducting circuits

Physical Review Research
Large-scale quantum computers will inevitably need quantum error correction (QEC) to protect information against decoherence. Given that the overhead of such error correction is often formidable, autonomous quantum error correction (AQEC) proposals offer

On the robustness of bucket brigade quantum RAM

New Journal of Physics, 2015
We study the robustness of the bucket brigade quantum random access memory model introduced by Giovannetti et al (2008 Phys. Rev. Lett. http://dx.doi.org/10.1103/PhysRevLett.100.160501 100 http://dx.doi.org/10.1103/PhysRevLett.100.160501 ).
