Abstract

Recent advances in nanotechnology allow very accurate manipulation of small collections of quantum dots (QDs), an important step in semiconductor-based quantum computation. As the number of QDs in a device grows, it becomes increasingly useful to control the system with as few voltage changes as possible. The authors offer a protocol, ``CODA'', both to efficiently identify sparse sets of voltage changes for controlling a quantum system, and to introduce a metric for comparing device designs. As a method for efficiently controlling $a\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}d$ designing a device, CODA will impact engineering solutions to the extension of semiconductor-based quantum computation.

Compressed optimization of device architectures

Adam Frees, John King Gamble, Daniel R. Ward +4 more

Note: This preprint has been superseded by arXiv:1806.04318. Recent advances in nanotechnology have enabled researchers to control individual quantum mechanical objects with unprecedented accuracy, opening the door for both quantum and extreme-scale conventional computing applications. As these devices become larger and more complex, the ability to design them such that they can be simply controlled becomes a daunting and computationally infeasible task. Here, motivated by ideas from compressed sensing, we introduce a protocol for the Compressed Optimization of Device Architectures (CODA). It leads naturally to a metric for benchmarking device performance and optimizing device designs, and provides a scheme for automating the control of gate operations and reducing their complexity. Because CODA is computationally efficient, it is readily extensible to large systems. We demonstrate the CODA benchmarking and optimization protocols through simulations of up to eight quantum dots in devices that are currently being developed experimentally for quantum computation.

Colloquium : Advances in automation of quantum dot devices control

Justyna P. Zwolak, Jacob M. Taylor

Arrays of quantum dots (QDs) are a promising candidate system to realize scalable, coupled qubit systems and serve as a fundamental building block for quantum computers. In such semiconductor quantum systems, devices now have tens of individual electrostatic and dynamical voltages that must be carefully set to localize the system into the single-electron regime and to realize good qubit operational performance. The mapping of requisite QD locations and charges to gate voltages presents a challenging classical control problem. With an increasing number of QD qubits, the relevant parameter space grows sufficiently to make heuristic control unfeasible. In recent years, there has been considerable effort to automate device control that combines script-based algorithms with machine learning (ML) techniques. In this Colloquium, a comprehensive overview of the recent progress in the automation of QD device control is presented, with a particular emphasis on silicon- and GaAs-based QDs formed in two-dimensional electron gases. Combining physics-based modeling with modern numerical optimization and ML has proven effective in yielding efficient, scalable control. Further integration of theoretical, computational, and experimental efforts with computer science and ML holds vast potential in advancing semiconductor and other platforms for quantum computing.

Advances in Modeling of Noisy Quantum Computers: Spin Qubits in Semiconductor Quantum Dots

Davide Costa, Mario Simoni, Gianluca Piccinini +1 more

The new quantum era is expected to have an unprecedented social impact, enabling the research of tomorrow in several pivotal fields. These perspectives require a physical system able to encode, process and store for a sufficiently long amount of time the quantum information. However, the optimal engineering of currently available quantum computers, which are small and flawed by several non-ideal phenomena, requires an efficacious methodology for exploring the design space. Hence, there is an unmet need for the development of reliable hardware-aware simulation infrastructures able to efficiently emulate the behaviour of quantum hardware that commits to looking for innovative systematic ways, with a bottom-up approach starting from the physical level, moving to the device level and up to the system level. This article discusses the development of a classical simulation infrastructure for semiconductor quantum-dot quantum computation based on compact models, where each device is described in terms of the main physical parameters affecting its performance in a sufficiently easy way from a computational point of view for providing accurate results without involving sophisticated physical simulators, thus reducing the requirements on CPU and memory. The effectiveness of the involved approximations is tested on a benchmark of quantum circuits — in the expected operating ranges of quantum hardware — by comparing the corresponding outcomes with those obtained via numeric integration of the Schrödinger equation. The achieved results give evidence that this work is a step forward towards the definition of a classical simulator of quantum computers.

Controlled Quantum Operations of a Semiconductor Three-Qubit System

Hai-Ou Li, Gang Cao, Guodong Yu +4 more

In semiconductor-based quantum computing, gate operations beyond the two-qubit limit are important, but have remained extremely challenging. The authors realize gate-voltage control of interqubit couplings in a specially designed three-qubit quantum-dot device. They exercise coherent control of both amplitude and phase of a target qubit using the prepared states of two control qubits, and demonstrate the basic functionalities of the universal Toffoli gate. This initial effort to achieve controlled three-qubit operations provides useful insight for research on multiqubit systems in semiconductor devices.

A Quantum-Computing-Based Method for Solving Quantum Confinement Problem in Semiconductor

Ning Yang, Jing Hua Guo

Technology computer-aided design (TCAD) of semiconductor devices relies on the numerical solution of differential equations in devices. Recent advances in quantum computing provide a new opportunity for TCAD simulations to be performed on a quantum computer. Based on a variational quantum algorithm, we develop a quantum-computing-based method to solve quantum confinement problems in semiconductor nanostructures. As the number of numerical discretization grid points for solving the Schrödinger equation increases, the number of qubits needed scales only logarithmically, ~${O}[\log(N)]$. The method is applied to solve quantum confinement problems at all dimensions, which are related to confinement in a quantum well, semiconductor nanowire, and semiconductor quantum dot structures. The method can treat an anisotropic band structure and electrostatic potential in semiconductor nanostructures. We further show that the design of ansatz plays an important role in the performance of the method in terms of solution accuracy. The quantum-computing-based method can compute the energies and wave functions of both the ground and excited states with high accuracy.

Automated Extraction of Capacitive Coupling for Quantum Dot Systems

Joshua Ziegler, Florian Luthi, Mick Ramsey +3 more

Single electrons trapped on semiconductor-defined quantum dots (QDs) are a promising platform for large-scale quantum computing. The authors demonstrate a reliable, automated method to identify the capacitive coupling between QDs. The approach combines machine learning with traditional fitting, to take advantage of the desirable properties of each. Also, analysis of cross capacitance may be used for automatic identification of the spurious QDs that occasionally form during device tuning. These techniques can autonomously flag devices with spurious dots near the operating regime, which is crucial information for reliable tuning for qubit operations.
