Abstract: A method, system, and computer program product for empirically identifying a dynamical decoupling sequence for error suppression on a quantum computer. A training quantum circuit, with an equivalent circuit structure to the target quantum circuit, is selected to identify the optimal dynamical decoupling sequence. A population of dynamical decoupling sequences represented as sequences in a genetic algorithm is generated. Offsprings of a selected set of sequences (“parents”) from the population are then generated via reproduction and mutation forming candidate dynamical decoupling sequences, which refer to those dynamical decoupling sequences that may be selected to be used as a “parent” in a subsequent iteration for generating offsprings or selected as the dynamical decoupling sequence to run on the target quantum circuit. One or more dynamical decoupling sequences are selected from the candidate dynamical decoupling sequences based on their fitness with the objective function.

Abstract: Systems and techniques that facilitate measurement aggregation in quantum programs are provided. In various embodiments, a system can comprise an input component that can access a quantum program. In various instances, the system can further comprise an aggregation component that can aggregate quantum measurement instructions that are listed in the quantum program. In various embodiments, the aggregation component can aggregate the quantum measurement instructions by: identifying a first quantum measurement instruction in the quantum program; identifying another quantum instruction in the quantum program that is adjacent to the first quantum measurement instruction; and swapping and/or merging the first quantum measurement instruction with the another quantum instruction based on determining whether the first quantum measurement instruction and the another quantum instruction share qubits and based on determining whether the another quantum instruction is a quantum measurement instruction.

Abstract: A method, system and computer program product for mitigating errors in measurements from a quantum system. A discriminator is trained to classify the measurement results of the quantum states of qubits as corresponding to a first quantum state (e.g., quantum state of 0) or a second quantum state (e.g., quantum state of 1). A first region of trust (corresponding to trusted measurements of a first quantum state) with a first discriminator boundary and a second region of trust (corresponding to trusted measurements of a second quantum state) with a second discriminator boundary are defined using the trained discriminator. If a shot-to-shot measurement result of a qubit state falls outside such regions of trust, the measurement result is rejected. In this manner, measurement errors from a quantum system are effectively mitigated, including measurement errors involving shot-to-shot measurement results of the quantum states read from the execution of the quantum circuits.
