Quantum error correction procedures have the potential to enable faithful operation of large-scale quantum computers. They protect information from environmental decoherence by storing it in logical qubits, built from ensembles of entangled physical qubits according to suitably tailored quantum error correcting encodings. To date, no generally accepted framework to characterise the behaviour of logical qubits as quantum memories has been developed. In this work, we show that generalisations of…

Relaxation times do not capture logical qubit dynamics.
This work shows that generalisations of well-established figures of merit of physical qubits to logical qubits fail and do not capture dynamics of logical qu bits, and shows that a suitable set of observables, formed by code space population and logical operators within the code space, allows one to track and characterize the dynamical behaviour of logicalqubits.


Quantum computations on a topologically encoded qubit
A quantum error-correcting code in which one qubit is encoded in entangled states distributed over seven trapped-ion qubits, which represents a fully functional instance of a topologically encoded qubit, or color code, and opens a route toward fault-tolerant quantum computing.
Realization of quantum error correction
In principle, the approach enables a quantum state to be maintained by means of repeated error correction, an important step towards scalable fault-tolerant quantum computation using trapped ions.
Realization of three-qubit quantum error correction with superconducting circuits
This work encodes a quantum state, induce errors on the qubits and decode the error syndrome, which is used as the input to a three-qubit gate that corrects the primary qubit if it was flipped, and demonstrates the predicted first-order insensitivity to errors.
State preservation by repetitive error detection in a superconducting quantum circuit
The protection of classical states from environmental bit-flip errors is reported and the suppression of these errors with increasing system size is demonstrated, motivating further research into the many challenges associated with building a large-scale superconducting quantum computer.
Building logical qubits in a superconducting quantum computing system
This work describes the important route towards a logical memory with superconducting qubits, employing a rotated version of the surface code, laying the foundation towards scalable fault-tolerant quantum computers in the near future.
Fault-tolerant quantum error detection
This work shows the encoding and syndrome measurement of a fault-tolerantly prepared logical qubit via an error detection protocol on four physical qubits, represented by trapped atomic ions, demonstrating the robustness of a logical qu bit to imperfections in the very operations used to encode it.
Quantum error correction in a solid-state hybrid spin register
It is demonstrated that joint initialization, projective readout and fast local and non-local gate operations can all be achieved in diamond spin systems, even under ambient conditions, paving the way to large-scale quantum computation.
Topological quantum memory
We analyze surface codes, the topological quantum error-correcting codes introduced by Kitaev. In these codes, qubits are arranged in a two-dimensional array on a surface of nontrivial topology, and
Compiling Quantum Algorithms for Architectures with Multi-qubit Gates (Open Access, Publisher's Version)
A numerical optimization protocol that minimizes the number of required multi-qubit entangling gates by design is demonstrated and adapted for state preparation, and quantum algorithms including in-sequence measurements.
Experimental quantification of spatial correlations in quantum dynamics
Correlations between different partitions of quantum systems play a central role in a variety of many-body quantum systems, and they have been studied exhaustively in experimental and theoretical
