Bit-corrector circuits for photonic circuits with cascaded photonic gates

An integrated circuit, comprising:

• a photonic circuit including:
• one or more first inputs connected to a first set of optical connections, the one or more first inputs configured to receive, via the first set of optical connections, a set of photonic input signals, and
• a plurality of photonic gates configured to generate a first photonic output signal for the set of photonic input signals applied to the one or more first inputs;
• a photonic bit-corrector circuit including:
• one or more second inputs connected to a second set of optical connections, the one or more second inputs configured to receive, via the second set of optical connections, the set of photonic input signals, and
• a photonic gate configured to generate a second photonic output signal for the set of photonic input signals applied to the one or more second inputs;
• and
• an electronic circuit including:
• a first input connected to a first electrical connection, the first input configured to receive, via the first electrical connection, an electrical version of the second photonic output signal,
• a second input connected to a second electrical connection, the second input configured to receive, via the second electrical connection, a label signal, and
• one or more electrical circuits configured to:
• compare the electrical version of the second photonic output signal with the label signal, and
• output, based on comparing the electrical version of the second photonic output signal with the label signal, an electrical corrected version of the first photonic output signal.

A non-transitory computer-readable storage medium comprising stored instructions that, when executed by at least one processor, cause the at least one processor to:

• instruct a photonic circuit to:
• receive a set of photonic input signals, and
• generate a first photonic output signal for the set of photonic input signals applied to the photonic circuit;
• instruct a photonic bit-corrector circuit to:
• receive the set of photonic input signals, and
• generate a second photonic output signal for the set of photonic input signals applied to the photonic bit-corrector circuit;
• and
• instruct an electronic circuit coupled to the photonic circuit and the photonic bit-corrector circuit to:
• receive an electrical version of the second photonic output signal,
• receive a label signal,
• compare the electrical version of the second photonic output signal with the label signal, and
• output, based on comparing the electrical version of the second photonic output signal with the label signal, an electrical corrected version of the first photonic output signal.
