Artificial Intelligence (AI) is undeniably transforming the landscape of the technology sector, and recently, quantum computing has begun to unveil its potential to reshape the world as we know itAt the intersection of these two revolutionary trends lies a notable company striving to bridge these advanced technologies.

On December 18, SandboxAQ announced that it had completed a remarkable fundraising round, securing over $300 million, which catapulted its valuation to an astonishing $5.6 billionThis fundraising effort was led by Alger, with significant backing from existing investors such as TRowe Price and Breyer Capital, among others, including notable AI pioneer Yann LeCun.

The inception of this innovative company dates back to 2016 when Google co-founder Sergey Brin quietly embarked on an ambitious project within Alphabet

The initiative aimed to explore the integration of quantum computing with AI, and it was initially nested within Alphabet's Moonshot Factory, led by Jack Hidary, a long-time member of the X Prize board.

Eric Schmidt, the former CEO of Google and then-chairman of Alphabet, took a keen interest in this projectBy March 2022, this initiative successfully raised $500 million in its first funding round, leading to the establishment of SandboxAQ as a standalone entity, with Schmidt as chairman and Hidary as CEO“In SandboxAQ, AQ stands for AI and Quantum,” Hidary explained in an interview with BloombergThis succinct yet profound nomenclature encapsulates their ambitious technological vision, which diverges from mainstream large language models to focus on what they call Large Quantitative Models (LQMs).

To grasp the significance of SandboxAQ’s innovations, it is crucial to first understand the challenges currently faced in the field of AI

The mainstream large language models exhibit exceptional proficiency in learning language comprehension and generation by analyzing vast amounts of text available on the internetHowever, when addressing specific scientific calculations, material design, or drug development, these models often fall shortThis limitation arises not from their linguistic capabilities but from an inability to accurately navigate the underlying principles of physics and mathematical relationships required in these domains.

Recognizing this gap, SandboxAQ has set out to develop their own solution in the form of Large Quantitative ModelsUnlike traditional large language models that learn and generate content by processing unstructured textual data, LQMs originate from mathematical equations and physical principles, thus creating their own training data.

The technological architecture of LQMs fundamentally differs from conventional transformer models

Instead, it employs a combination of neural network models and knowledge graphsThis distinctive design enables the models to not only generate data through equations but also to receive inputs from sensors or other quantitative data sourcesCrucially, it allows for an accurate capture of causal relationships and constraints within physical systems.

SandboxAQ’s unique technological pathway has already demonstrated significant advantages within the financial sectorTraditional methods for financial risk assessment hinge on Monte Carlo simulations that utilize random sampling to derive outcomesHowever, when faced with the modern complexities of structured financial instruments, these methods often fall short“If we wish to understand a portfolio's tail risk under various market conditions, traditional methods struggle to provide insight

Our LQM aims to create between 300 million to 500 million slight variations of that portfolio and then systematically analyze the risk profiles across each scenario," Hidary emphasized.

While it is true that quantum computing can directly simulate such systems using the language of quantum mechanics, achieving this remains a complex endeavor that may take decades to fulfillCurrent quantum computing technologies still face numerous challenges, particularly regarding the error rates of qubitsDespite Google’s recent breakthroughs with its Willow chip addressing this issue, substantial hurdles remain before we can realize large-scale quantum computers.

To tackle these challenges, SandboxAQ has devised a new algorithm based on tensor networks, a concept that originates from the field of quantum many-body physics

This algorithm harnesses a fundamental property of nature known as localityIn layman's terms, locality implies that distant parts of a system, such as two far-apart atoms in a long molecule, do not interact meaningfullyBy utilizing this principle, the tensor network algorithm efficiently represents quantum states in accordance with the "entanglement area law."

Through cultivating a deep technological partnership with Nvidia, SandboxAQ has extended the functionalities of the CUDA library, enabling standard GPUs to support quantum computing processesThis development allows them not to wait for the advent of real quantum computers but to enable existing hardware to conduct quantum simulations, while also integrating quantum processing units (QPUs) in the future

In one research study, SandboxAQ’s team utilized Google’s tensor processing units (TPUs), achieving a remarkable feat by completing high-dimensional optimization involving over 600 billion parameters in just 24 hours, setting a world record in tensor network computation.

In practical applications, SandboxAQ’s technology has revealed distinctive value across various sectorsFor instance, in pharmaceutical development, addressing traditionally challenging diseases like cancer or Alzheimer’s disease often presents limited clinical data, rendering data-driven AI approaches less effectiveHowever, SandboxAQ’s quantum heuristic algorithms can accurately simulate interactions between drug molecules and human receptors, starting from the fundamental physical characteristics of molecules.

The system initially generates numerous molecular structure variants based on quantum chemistry equations

Each variant undergoes testing through quantum heuristic algorithms that predict its behavior within real-world environmentsThese predictions are subsequently integrated into neural networks, blending with information derived from sensors and other quantitative data sources to achieve a more comprehensive understanding of the target systemThis process effectively identifies the most promising candidate molecules before laboratory synthesis, thereby accelerating drug development and significantly lowering costs and risks associated with R&D.

The potential applications of this innovative technology extend beyond pharmaceuticals, revealing exciting prospects in cybersecurity, material science, and more.

With this latest funding round complete, SandboxAQ, which aims to fuse these two groundbreaking technologies, is poised to advance further along the path of technological innovation
