Quantum computers promise tremendous impact across applications—and have shown
great strides in hardware engineering—but remain notoriously error prone. Careful design of …

Efforts to scale-up quantum computation have reached a point where the principal limiting
factor is not the number of qubits, but the entangling gate infidelity. However, the highly …

We describe an experimental effort designing and deploying error-robust single-qubit
operations using a cloud-based quantum computer and analog-layer programming access …

We develop a framework of" semi-automatic differentiation" that combines existing gradient-
based methods of quantum optimal control with automatic differentiation. The approach …

In this work, we extend a multiqubit benchmarking technique known as the binned output
generation (BOG) in order to discriminate between coherent and incoherent noise sources …

The qocttools code performs optimization calculations on quantum systems using optimal
control theory. The problem that it solves is the following: given a system governed by a …

Autocorrelated noise appears in many solid-state qubit systems and hence needs to be
taken into account when developing gate operations for quantum information processing …

In the context of quantum hardware needing to operate in highly controlled environments
(such as laboratories and research centers), networking communication is essential. This …
