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.
Claims17
A quantum computing system, comprising:
- a plurality of gates;
- a plurality of tetrons;
- 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 measurement of checks associated with respective honeycomb edge directions and connections of paired qubits defined by the plurality of tetrons that are adjacent as assigned to vertices of the honeycomb.

A control system for a quantum computer, comprising:
- a processing device;
- and
- at least one computer-readable storage device coupled to the processing device and having processor-executable instructions that are operable to:
- measure checks associated with respective honeycomb edge directions and connections of paired qubits in a quantum processor defined by a plurality of tetrons that are adjacent as assigned to vertices of a honeycomb;
- apply a honeycomb code in a quantum processor and identify an error based on the applied honeycomb code, wherein the honeycomb code is applied based on the measured checks.
