Shuttling an Electron Spin through a Silicon Quantum Dot Array
A. Zwerver, S. Amitonov, S. L. de Snoo +5 more·Sep 2, 2022
Coherent links between qubits separated by tens of micrometers are expected to facilitate scalable quantum computing architectures for spin qubits in electrically-defined quantum dots. These links create space for classical on-chip control electronic...
Feature Selection for Classification with QAOA
G. Turati, Maurizio Ferrari Dacrema, P. Cremonesi·Sep 1, 2022
Feature selection is of great importance in Machine Learning, where it can be used to reduce the dimensionality of classification, ranking and prediction problems. The removal of redundant and noisy features can improve both the accuracy and scalabil...
Reducing Runtime Overhead via Use-Based Migration in Neutral Atom Quantum Architectures
Andrew Litteken, Jonathan M. Baker, F. Chong·Sep 1, 2022
Neutral atoms are a promising choice for scalable quantum computing architectures. Features such as long distance interactions and native multiqubit gates offer reductions in communication costs and operation count. However, the trapped atoms used as...
Relating the multi-angle quantum approximate optimization algorithm and continuous-time quantum walks on dynamic graphs
R. Herrman·Sep 1, 2022
In this work, we show that ma-QAOA is equivalent to a restriction of continuous-time quantum walks on dynamic graphs. We then show it is universal for computation by finding the appropriate $B$ and $C$ operators and angles that implement the universa...
Decomposition of matrix product states into shallow quantum circuits
Manuel S. Rudolph, Jing Chen, J. Miller +2 more·Sep 1, 2022
Tensor networks (TNs) are a family of computational methods built on graph-structured factorizations of large tensors, which have long represented state-of-the-art methods for the approximate simulation of complex quantum systems on classical compute...
Accelerating Polynomial Multiplication for Homomorphic Encryption on GPUs
Kaustubh Shivdikar, Gilbert Jonatan, Evelio Mora +6 more·Sep 1, 2022
Homomorphic Encryption (HE) enables users to securely outsource both the storage and computation of sensitive data to untrusted servers. Not only does HE offer an attractive solution for security in cloud systems, but lattice-based HE systems are als...
Quantum mixed state compiling
Nic Ezzell, E. Ball, Aliza U. Siddiqui +4 more·Sep 1, 2022
The task of learning a quantum circuit to prepare a given mixed state is a fundamental quantum subroutine. We present a variational quantum algorithm (VQA) to learn mixed states which is suitable for near-term hardware. Our algorithm represents a gen...

Joshua Viszlai, T. Tomesh, P. Gokhale +2 more·Sep 1, 2022
Recent work has proposed and explored using coreset techniques for quantum algorithms that operate on classical data sets to accelerate the applicability of these algorithms on near-term quantum devices. We apply these ideas to Quantum Boltzmann Mach...
Advanced Quantum Poisson Solver in the NISQ era

In this paper, we present a hybrid quantum/classical algorithm to solve an NP-hard combinatorial problem called the multiple target data association (MTDA) and tracking problem. We use diabatic quantum annealing (DQA) to enumerate the low energy, or ...
Cycle index polynomials and generalized quantum separability tests
Zachary P. Bradshaw, Margarite L. LaBorde, M. Wilde·Aug 31, 2022
The mixedness of one share of a pure bipartite state determines whether the overall state is a separable, unentangled one. Here we consider quantum computational tests of mixedness, and we derive an exact expression of the acceptance probability of s...
