Abstract
Aspects of the disclosure include sending inputs according to the Floquet codes to be processed by a quantum circuit and receiving data streams from the quantum circuit, in response to the inputs. The data streams are encoded into a predetermined number of bits according to a probability density function for noise. The data streams are classified into hard outcomes having likelihoods of correctness, the hard outcomes representing output of the quantum circuit.
Claims20
A method for decoding Floquet codes, the method comprising:
- sending inputs according to the Floquet codes to be processed by a quantum circuit;
- receiving data streams from the quantum circuit, in response to the inputs;
- encoding the data streams into a predetermined number of bits according to a probability density function for noise;
- and
- classifying the data streams into hard outcomes having likelihoods of correctness, the hard outcomes representing output of the quantum circuit.
A system having a memory, computer readable instructions, and a processor for executing the computer readable instructions, the computer readable instructions controlling the processor to perform operations comprising:
- sending inputs according to Floquet codes to be processed by a quantum circuit;
- receiving data streams from the quantum circuit, in response to the inputs;
- encoding the data streams into a predetermined number of bits according to a probability density function for noise;
