Abstract
A quantum error correcting code with dynamically generated logical qubits is provided. When viewed as a subsystem code, the code has no logical qubits. Nevertheless, the measurement patterns generate logical qubits, allowing the code to act as a fault-tolerant quantum memory. Each measurement can be a two-qubit Pauli measurement.
Claims10
1-11. (canceled)
A quantum computing system, comprising:
- a plurality of gates;
- a plurality of physical qubits;
- and
- a processing device coupled to apply a honeycomb code and identify an error based on the applied honeycomb code, wherein the honeycomb code is applied based on checks associated with respective honeycomb edge directions and connections of paired physical qubits that are adjacent as assigned to vertices of the honeycomb.
