How memQ Is Shaping the Quantum Landscape With Ansys Tools

The quantum computing landscape is quickly expanding on a global scale, with projections estimating that it will hit $12.6 billion by 2032. This rapid development is driven by many factors, including advancements in artificial intelligence (AI), the need for stronger cyber-defense mechanisms, and the desire to solve complex problems that traditional computing cannot address.

The industry is particularly present in the midwestern United States, where Chicago is fast emerging as a significant player. Fueled by substantial government investments that foster the creation of a robust quantum ecosystem, the Chicago area is quickly becoming a hub for quantum computing.

One of the primary challenges in this field is developing an efficient and scalable quantum network architecture. Current classical networking methods are inadequate for quantum applications - while classical bits are either 0 or 1, quantum bits (qubits) have the unique ability to be in multiple states at once, a property known as superposition. However, this quantum state can easily collapse, rendering it ineffective for meaningful progress. The goal of quantum architecture is to manage qubit interactions over distances while preserving their fragile quantum state. Achieving this would enable the seamless connection of quantum computers, which is critical for the technology's scalability and fast adoption.

Amid this expanding environment, Chicago-based quantum computing innovator memQ stands out as an innovative company contributing significantly to the field. By leveraging tools from Ansys, part of Synopsys, memQ is paving the way for breakthroughs that could redefine computing as we know it.

Who Is memQ?

memQ, named for a shortened version of "memory qubits," is at the forefront of quantum technology. The company aims to harness the power of different types of qubits through quantum network connectivity, spanning multiple systems to solve the toughest compute problems.

The company, which spun out from the University of Chicago and Argonne National Laboratory, launched in 2022. memQ has maintained an ongoing relationship with both institutions, which has been pivotal in driving collaborative projects and recruitment efforts. It was co-founded by Manish Singh, Ph.D., and Sean Sullivan, Ph.D., who serve as CEO and CTO of memQ, respectively.

Simulating at the Smallest Scale

memQ leverages the advanced photonics capabilities of Ansys tools to advance quantum technology. Singh says, "For us, the photonics capabilities are what brought us to Ansys software. … It has kind of become the de facto when it comes to photonic simulations. Lumerical software is a very powerful tool."

Specifically, the company uses the Ansys Lumerical suite to engineer the properties of light, enabling interactions with single atoms. This tool is crucial for memQ, as it enables them to run a wide range of simulations before moving to the physical product stage. This not only reduces development time but also significantly lowers costs, making the development process more efficient.

Additionally, leveraging Ansys Gateway powered by AWS software has been a game-changer. This tool enables memQ to benefit from the Amazon Web Services (AWS) credits available to early startups, which give access to services, support, and resources from Amazon. The AWS credits help memQ manage costs effectively while still leveraging powerful computational resources.

How memQ Uses Ansys To Innovate at the Quantum Level

Simulation enables memQ to mimic complex interactions at the atomic level, and such precision is crucial for the development of reliable and scalable quantum networks. memQ's approach to using simulation tools involves initial in-house fabrication and short feedback loops to refine their designs. Once they are confident in their simulations, they proceed to external foundries for more extensive fabrication. This method ensures that they are well-prepared, reducing the time and cost associated with lengthy testing cycles. The scripting capabilities of Ansys tools also play a significant role in memQ's workflow. With these features, memQ can adjust multiple parameters to optimize the interaction between light and single atoms in their simulations. For example, tweaking the size and spacing of holes in a photonic crystal cavity can drastically alter the properties of the cavity, which in turn affects how well it interacts with atoms. Ansys tools also enable memQ to predict how their component's performance will vary with foundry process variation, ensuring high device yields for scalable manufacturing.

memQ plans to incorporate other Ansys tools as they expand. For instance, they anticipate using Ansys HFSS high-frequency electromagnetic simulation software to simulate the microwave circuit components used to address and control qubits. Also, the team plans to expand their use of the Lumerical suite with the addition of Ansys Lumerical INTERCONNECT photonic integrated circuit design and simulation software in their control and entanglement hub photonic integrated circuits (PICs).

Quantum Computing Industry Outlook

Commercial applications of quantum computing are anticipated within the next three to five years, marking an exciting period for industry stakeholders. As these applications become more prevalent, the demand for resilient quantum networking solutions will increase. Initiatives like those led by memQ, which focus on creating an extensible quantum network architecture, will be vital for reducing the barriers to entry for new adopters and accelerating the commercialization of quantum technologies.

memQ's plans to build extensible quantum network technology (xQNA) have three main modules that together connect modular quantum computers at all length scales.

memQ's unique approach leverages existing infrastructure, which not only lowers the risk associated with adopting quantum technologies but also speeds up market entry. This strategy is essential for enabling widespread use of quantum computing, potentially transforming sectors such as healthcare, finance, and logistics.

By utilizing Ansys' simulation tools, memQ optimizes its silicon-based quantum hardware designs for better manufacturability and performance, helping to reduce the need for costly prototypes and speed up the development process.

As the industry continues to grow, the focus will likely shift towards more integrated multiphysics simulations. The ability to simulate multiple physics within the same software solution will become increasingly important for developing complex quantum systems that can perform reliably in real-world applications.

The Future of Quantum Computing

By harnessing the power of Ansys simulation tools, memQ is making significant strides in optimizing its silicon-based quantum hardware designs. Looking ahead, the company is setting the stage for broad-scale adoption of quantum computing technologies. By combining their expertise and Ansys resources, memQ is optimizing hardware designs and reducing development cycles, paving the way for the future of this game-changing technology.

As the quantum industry evolves, the role of simulation will only become more critical. For memQ, the ongoing relationship with Ansys ensures they remain at the forefront of this dynamic field, ready to capitalize on new opportunities and overcome emerging challenges. Together, they are not just contributing to the quantum computing ecosystem but also helping to shape its future.
