• Abstract: We present an error mitigation scheme which corrects readout errors on Noisy Intermediate-Scale Quantum (NISQ) computers [1,2]. After a short review of applying the method to one qubit, we proceed to discuss the case when correlations between different qubits occur. We demonstrate how the readout error can be mitigated in this case. By performing experiments on IBMQ hardware, we show that such correlations do not have a strong effect on the results, justifying to neglect them.

• Feedforward suppression of readout-induced faults in quantum error correction [0.0]
  Method consists of an adaptive readout sequence conditioned on each check qubit's readout result from the previous cycle. For readout errors, correlated preparation errors and measurement-induced leakage that are stronger in a particular qubit state, this feedforward protocol can suppress the physical qubit errors.

  We study the structure of non-Markovian correlated errors and their impact on surface code memory performance. Our analysis shows that while not all temporally correlated structures are detrimental, certain structures, particularly multi-time "streaky" correlations, can severely degrade logical error rate scaling.

• The Accuracy vs. Sampling Overhead Trade-off in Quantum Error Mitigation Using Monte Carlo-Based Channel Inversion [84.66087478797475]
  Quantum error mitigation (QEM) is a class of promising techniques for reducing the computational error of variational quantum algorithms. We consider a practical channel inversion strategy based on Monte Carlo sampling, which introduces additional computational error. We show that when the computational error is small compared to the dynamic range of the error-free results, it scales with the square root of the number of gates.

  We study coherent errors on a quantum hardware platform using a transverse field Ising model Hamiltonian as a sample user application. We identify inter-day and intra-day qubit calibration drift and the impacts of quantum circuit placement on groups of qubits in different physical locations on the processor. This paper also discusses how these measurements can provide a better understanding of these types of errors and how they may improve efforts to validate the accuracy of quantum computations.

• Investigating the variance increase of readout error mitigation through classical bit-flip correction on IBM and Rigetti quantum computers [2.619913272279451]
  Readout errors are among the most dominant errors on current noisy intermediate-scale quantum devices. In this talk, we compare the performance of this method for IBM's and Rigetti's quantum devices. We derive a new expression for the variance of the mitigated Pauli operators in terms of the corrected expectation values and the noisy variances.

  State-of-the-art quantum platforms typically have physical error rates near $10-3$.

We implement 1D repetition codes embedded in a 2D grid of superconducting qubits which demonstrate exponential suppression of bit or phase-flip errors.

• Crosstalk Suppression for Fault-tolerant Quantum Error Correction with Trapped Ions [62.997667081978825]
  We present a study of crosstalk errors in a quantum-computing architecture based on a single string of ions confined by a radio-frequency trap, and manipulated by individually-addressed laser beams. This type of errors affects spectator qubits that, ideally, should remain unaltered during the application of single- and two-qubit quantum gates addressed at a different set of active qubits. We microscopically model crosstalk errors from first principles and present a detailed study showing the importance of using a coherent vs incoherent error modelling and, moreover, discuss strategies to actively suppress this crosstalk at the gate level.
