Autonomous Quantum Error Correction with Superconducting Qubits [PDF]

Large-scale quantum computers will inevitably need quantum error correction to protect information against decoherence. Traditional error correction typically requires many qubits, along with high-efficiency error syndrome measurement and real-time ...

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-

Maps on density operators preserving quantum f-divergences [PDF]

, 2013
For an arbitrary strictly convex function f defined on the non-negative real line we determine the structure of all transformations on the set of density operators which preserve the quantum f ...

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.

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.

Coherent-feedback formulation of continuous quantum error correction protocols [PDF]

, 2016
We propose an approach to continuous-time quantum error correction based on the coherent feedback of optical probes that naturally utilizes photonic device physics to implement a stationary and 'on-chip' protected quantum ...
