0000 In a general aspect, hardware-efficient encoding schemes for optimization problems are presented. In some cases, a quantum computing method includes associating subsets of qubits including data qubits and label qubits with clusters of variables in an optimization problem; and mapping the variables in each cluster to the data qubits associated with the cluster, such that multiple variables are mapped to each of the data qubits. During mapping basis states of the label qubits associated with the cluster are identified; the cluster is divided into groups of variables, each group of variables being associated with a respective one of the basis states; and for each group of variables, each variable in the group is mapped to a respective one of the data qubits associated with the cluster.

A chip-based quantum processor uses homonuclear molecules with non-zero nuclear spins. Each of these molecules serves as a qubit. To fabricate the quantum processor, a thin film of semiconductor atoms is deposited on a semiconductor substrate to form a protective under layer and over layer. A Group 15 or semiconductor molecular source forms a beam of dimer, triatomic, or tetratomic molecules that is deposited between the under layer and the over layer. Alternatively, fast Group 15 or semiconductor molecular ions are slowed and compressed in an ion funnel, or confined in an ion trap, and then deposited on top of the under layer at low energy. The quantum processor may be annealed to crystalize the deposited under layer and over layer. The deposited molecular qubits may be interrogated with electrodes, optical fields, microwave fields, or a combination thereof.

0000 The present disclosure introduces a differentiable framework for modeling quantum shot noise in state vector simulations used for training parameterized quantum circuits. Conventional approaches rely on multinomial sampling of measurement outcomes, which is inherently discrete and non-differentiable, blocking gradient-based optimization. To address this, the present disclosure replaces multinomial sampling with a continuous approximation using a multivariate Gaussian distribution that captures the statistical properties of shot noise. By applying a reparameterization technique, stochastic noise is expressed as a deterministic function of circuit parameters and auxiliary random variables, enabling gradients to propagate through the noise model. The method integrates noise directly into the quantum state vector, followed by normalization to maintain physical validity. This approach preserves differentiability while incorporating realistic noise effects, allowing efficient end-to-end training using standard optimization methods. The result is a scalable, noise-aware simulation framework that improves the fidelity and practicality of quantum machine learning development.

A controller of a quantum system causes performance of a single qubit gate on a target qubit. The controller causes a dressing field circuit to generate a dressing field at a target location where the target qubit is located. The dressing field modifies a set of initial states into a set of superposition states. A first (second) dressed state of the set of superposition states includes a non-zero contribution from a first (second) qubit state of the set of initial states. A dressed frequency difference between the first and second dressed states and a qubit frequency difference between the first and second qubit states are different. The controller causes a gate microwave signal characterized by the dressed frequency difference plus the qubit frequency difference to be incident on the target location. After a gate time, the controller controls operation of the dressing field circuit to stop generating the dressing field.
