Using error correction to determine the noise model

, 2007
Quantum error correcting codes have been shown to have the ability of making quantum information resilient against noise. Here we show that we can use quantum error correcting codes as diagnostics to characterise noise. The experiment is based on a three-

Quantum error correction beyond qubits

, 2008
Quantum computation and communication rely on the ability to manipulate quantum states robustly and with high fidelity. Thus, some form of error correction is needed to protect fragile quantum superposition states from corruption by so-called decoherence

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-

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 ).

Improved quantum metrology using quantum error-correction

, 2014
We consider quantum metrology in noisy environments, where the effect of noise and decoherence limits the achievable gain in precision by quantum entanglement.

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 proving the robustness of algorithms for early fault-tolerant quantum computers [PDF]

Quantum
The hope of the quantum computing field is that quantum architectures are able to scale up and realize fault-tolerant quantum computing. Due to engineering challenges, such ``cheap'' error correction may be decades away. In the meantime, we anticipate an

Joint encryption and error correction for secure quantum communication

Scientific Reports
Secure quantum networks are a bedrock requirement for developing a future quantum internet. However, quantum channels are susceptible to channel noise that introduce errors in the transmitted data.
