We consider a heterogeneous network of quantum computing modules, sparsely connected via Bell states. Operations across these connections constitute a computational bottleneck and they are likely to add more noise to the computation than operations performed within a module. We introduce several techniques for transforming a given quantum circuit into one implementable on such a network, minimising the number of Bell states required to do so. We extend previous works on circuit distribution to the case of heterogeneous networks. On the one hand, we extend the hypergraph approach of Andres-Martinez and Heunen (2019 Phys. Rev. A 100 032308) to arbitrary network topologies, and we propose the use of Steiner trees to detect and reuse common connections, further reducing the cost of entanglement sharing within the network. On the other hand, we extend the embedding techniques of Wu et al (2023 quantum 7 1196) to networks with more than two modules. We show that, with careful manipulation of trade-offs, these two new approaches can be combined into a single automated framework. Our proposal is implemented and benchmarked;the results confirm that our contributions make noticeable improvements upon the aforementioned works and complement their weaknesses.

In distributed quantum computing (DQC), reliable entanglement distribution across a network of quantum computers is crucial. During the quantum program compilation process, the timing and locations of required entanglement resources can be determined. Leveraging this information, we use the properties of quantum network hardware-specifically, the entanglement generation and quantum switch operation rates-to optimize quantum job execution schedules. This work presents a system that, given a set of quantum programs, extracts an Entaglement Demand Schedule (EDS) and generates an execution plan, including resource allocation tables and switch control instructions. We outline the system architecture and benchmark its performance using collections of randomized quantum programs, and describe further steps to enhance our system.

Due to the limitations of quantum device manufacturing technology, the number of qubits in current quantum computing devices is still relatively limited. distributed quantum computing, as an emerging quantum computing paradigm, aims to achieve larger-scale quantum computation. To reduce the cost of state transfer and routing in distributed quantum circuits, this paper focuses on the transmission direction of global gates generated after quantum circuit partitioning. We provide a threshold for the number of state transfers required for converting global gates to local gates in the entire circuit. We propose a method to evaluate the quality of transmission directions and utilize a genetic algorithm to find the optimal transmission directions for minimizing the transmission cost of distributed quantum circuit. Based on the optimized transmission directions, this paper maps the qubits in the logical circuit to a distributed quantum architecture model and presents a method for converting global gates to local gates in the quantum circuit. The routing process of distributed quantum circuits is simulated. Experimental results show that compared to existing methods for reducing the number of state transfers, the proposed algorithm can achieve a lower overall cost for executing distributed quantum circuits.

As the works on quantum computing have seen substantial development in recent years, we are on the verge of seeing the fruitful result of the preliminary, early version of quantum computers. Nevertheless, in order to achieve full-fledged, large-scale quantum computers, two aspects still lacking in the existing quantum computers, i.e., scalability and reliability, will need to be more carefully considered and investigated. In this survey, we present a review of existing literature that aims to alleviate the scalability and reliability issues in quantum computers. In particular, we discuss how existing research leads to two main solutions: for advancing scalability, a distributed quantum computing (DQC) paradigm will be the primary direction instead of the general centralized quantum computing (CQC), whereas for attaining reliability, a fault-tolerant quantum computation (FTQC) approach would need to be leveraged instead of the existing noisy intermediate-scale quantum computers (NISQ). Combining both solutions, we highlight the essentiality of fault-tolerant distributed quantum computation (FT-DQC) and present related progress in the field. Furthermore, from the papers that we have gathered, we provide the taxonomy of the works to give a clearer landscape of the field and discuss the key issues in realizing FT-DQC. © 2025 The Authors

This paper introduces a noise -aware distributed quantum Approximate Optimization Algorithm (QAOA) tailored for execution on near-term quantum hardware. Leveraging a distributed framework, we address the limitations of current Noisy Intermediate -Scale quantum (NISQ) devices, which are hindered by limited qubit counts and high error rates. Our approach decomposes large QAOA problems into smaller subproblems, distributing them across multiple quantum Processing Units (QPUs) to enhance scalability and performance. The noise -aware strategy incorporates error mitigation techniques to optimize qubit fidelity and gate operations, ensuring reliable quantum computations. We evaluate the efficacy of our framework using the HamilToniQ Benchmarking Toolkit, which quantifies the performance across various quantum hardware configurations. The results demonstrate that our distributed QAOA framework achieves significant improvements in computational speed and accuracy, showcasing its potential to solve complex optimization problems efficiently in the NISQ era. This work sets the stage for advanced algorithmic strategies and practical quantum system enhancements, contributing to the broader goal of achieving quantum advantage.

The current quantum landscape is characterised by a wide variety of quantum computers, each with unique capabilities and limitations. Despite its rapid advancement, this field is still in its early stages and lacks essential software engineering principles such as resilience and customisability by design. To provide developers with a quantum technology stack that embeds these principles by design, we propose leveraging the heterogeneity of existing quantum computers. Specifically, we introduce a novel distribution methodology, termed shot-wise, to distribute the quantum computation workload of a single circuit execution (i.e., its shots) across multiple quantum computers. This shot-wise methodology is highly customisable, allowing for the embedding of user-specific and scenario-specific requirements into the distribution process. Requirements can be expressed through constraints, such as the geographical location of the QPUs, and their architecture, or ensuring or avoiding specific combinations of QPUs and quantum providers. Additionally, requirements can be defined by one or more objective functions to be minimised or maximised, such as reducing waiting time, computation cost, or energy footprint. By also combining constraints and objective functions, our shot-wise methodology enhances flexibility and improves the overall resilience of quantum computations against potential quantum computer failures. Preliminary results indicate that this approach offers error rates comparable to, or lower than, those of single-device execution even in all the tested scenarios with different numbers of qubits, families of circuits and number of QPUs to distribute the shots.

Connecting quantum computers to a quantum network opens a wide array of new applications, such as securely performing computations on distributed data sets. Near-term quantum networks are noisy, however, and hence correctness and security of protocols are not guaranteed. To study the impact of noise, we consider a multiparty summation protocol with imperfect shared entangled states. We study analytically the impact of both depolarising and dephasing noise on this protocol and the noise patterns arising in the probability distributions. We conclude by eliminating the need for a trusted third party in the protocol using Shamir's secret sharing.

quantum computing holds promise for performing optimization tasks efficiently, but its potential is currently hindered by the presence of noisy qubits and short coherence times in noisy intermediate scale quantum devices, limiting their practical use to small-scale problems. As a solution, multi-chip quantum computing presents an attractive alternative. We have developed two multi-chip mapping methods that maximize compute capacity utilization of quantum processing units (QPUs) while addressing their limited coherence times and the transmission rates of quantum interconnects. These methods assess critical parameters of QPUs and interconnects in a multi-chip quantum network, enabling optimal assignment of quantum gates in a quantum algorithm onto the network. Our methods produce runnable subcircuits, mapped to a minimum number of capacity-maximized QPUs while achieving high-fidelity multi-chip quantum computing.

quantum computing holds immense promises for solving complex problems by leveraging quantum mechanics in a computational paradigm. However, challenges around the computational limitations of current noisy intermediate-scale quantum computers make it difficult to widely apply quantum advantages. These machines, with a limited number of qubits and high error rates, struggle to execute large quantum circuits, with higher dimensions of depth, size or width. To address those challenges, distributing circuits among processing agents or cutting circuits in small segments to be run in sequence are considered viable approaches to enhance scalability and computational power. The main goal for this paper is to present a hypergraphic representation approach for quantum circuit cutting, applicable to spatial and temporal scenario, using hypergraphic theory and heuristics. For each approach, the target is to reduce communication costs in the spatial scenario, and the initialization cost in the temporal scenario. To accomplish this, we apply heuristics for hypergraphic partitioning, considering the high level representation of the quantum circuit with different combinations of quantum gates. We compared results against different heuristics, such as Stoer-Wagner, Fiduccia-Mattheyses, and Kernighan-Lin, creating graphics based in a new circuit dimension called, coupling ratio for the circuit. The observed results from this method indicate the hypergraphic partitioning process as a critical step as part of a new reference architecture for quantum computers, in distributed quantum computing environments.

A million qubit-scale quantum computer is essential to realize the quantum supremacy. Modern large-scale quantum computers integrate multiple quantum computers located in dilution refrigerators (DR) to overcome each DR's unscaling cooling budget. However, a large-scale multi-DR quantum computer introduces its unique challenges (i.e., slow and erroneous inter-DR entanglement, increased qubit scale), and they make the baseline error handling mechanism ineffective by increasing the number of gate operations and the interDR communication latency to decode and correct errors. Without resolving these challenges, it is impossible to realize a fault-tolerant large-scale multi-DR quantum computer. In this paper, we propose a million qubit-scale distributed quantum computer which uses a novel error handling mechanism enabling fault-tolerant multi-DR quantum computing. First, we apply a low-overhead multi-DR error syndrome measurement (ESM) sequence to reduce both the number of gate operations and the error rate. Second, we apply a scalable multi-DR error decoding unit (EDU) architecture to maximize both the decoding speed and accuracy. Our multiDR error handling SW-HW co-design improves the ESM latency, ESM errors, EDU latency, and EDU accuracy by 3.7 times, 2.4 times, 685 times, and 6.1 center dot 10(10) times, respectively. With our scheme applied to assumed voltage-scaled CMOS and mature ERSFQ technologies, we successfully build a fault-tolerant million qubit-scale quantum computer.
