Query: Error Mitigation in Quantum Computers through Instruction Scheduling   Quantum systems have potential to demonstrate significant computational
advantage, but current quantum devices suffer from the rapid accumulation of
error that prevents the storage of quantum information over extended periods.
The unintentional coupling of qubits to their environment and each other adds
significant noise to computation, and improved methods to combat decoherence
are required to boost the performance of quantum algorithms on real machines.
While many existing techniques for mitigating error rely on adding extra gates
to the circuit, calibrating new gates, or extending a circuit's runtime, this
paper's primary contribution leverages the gates already present in a quantum
program without extending circuit duration. We exploit circuit slack for
single-qubit gates that occur in idle windows, scheduling the gates such that
their timing can counteract some errors.
  Spin-echo corrections that mitigate decoherence on idling qubits act as
inspiration for this work. Theoretical models, however, fail to capture all
sources of noise in NISQ devices, making practical solutions necessary that
better minimize the impact of unpredictable errors in quantum machines. This
paper presents TimeStitch: a novel framework that pinpoints the optimum
execution schedules for single-qubit gates within quantum circuits. TimeStitch,
implemented as a compilation pass, leverages the reversible nature of quantum
computation to boost the success of circuits on real quantum machines.
