Q & A

What is the main focus of the current quantum computing research and development according to the speaker?

The speaker highlights that most of the current quantum computing research is focused on understanding how quantum computers work, defining algorithms, and preparing for future advancements such as better fidelity and increased qubit counts.

How does hybrid quantum-classical systems fit into the near-term applications of quantum computing?

Hybrid quantum-classical systems are expected to unlock value for industries by handling probabilistic applications that are currently challenging for classical computing, such as predicting economic recessions or fraud detection. These systems will coexist with CPUs and GPUs in data centers before fully fault-tolerant quantum computers are available.

What types of applications can benefit from quantum computing, and why are they better suited for quantum systems?

Probabilistic applications, like economic recession prediction, fraud detection, weather forecasting, and pharmaceutical research, can benefit from quantum computing because of the way qubits work, enabling quantum systems to handle these complex, uncertain problems more effectively than classical computers.

What is the expected timeline for the coexistence of quantum processing units (QPUs) with classical computing systems?

The speaker envisions that QPUs will start coexisting with CPUs and GPUs in data centers within the next three to five years, during the noisy era of quantum computing, before moving to more powerful fault-tolerant quantum systems.

What could be the long-term impact of fault-tolerant quantum computers in data centers?

In the long-term, fault-tolerant quantum computers may be standalone systems that take over full workloads in data centers, but they will still coexist with CPUs and GPUs to handle different computational tasks. The volume of QPUs may be smaller, but their value would be much higher.

Can you provide an example of a real-world application where quantum computing has shown potential to improve predictions?

An example is the collaboration with Moody's, where quantum computing was used to improve economic recession prediction accuracy from 77% (using classical computing) to 86% (using a quantum simulation), showcasing how quantum computing can enhance predictive capabilities in critical financial applications.

How does quantum computing aid in pharmaceutical research and drug development?

Quantum computing can help pharmaceutical research by simulating millions of potential drug molecules and protein folding variants, which classical computing cannot handle due to limitations in processing capacity. This allows researchers to explore a much broader set of potential solutions and more accurately predict the success of drug candidates.

Why is it important for quantum companies like Regetti to share research and tools with the broader community?

Sharing research and tools, like Regetti's Forest, with the community helps advance the field of quantum computing collectively. Although companies have shareholder interests, the speaker emphasizes that the quantum industry is still in its R&D phase, and it is critical to grow the market and ecosystem before worrying about competition for market share.

What is the expected timeline for achieving fully fault-tolerant quantum computers?

The speaker estimates that it will take at least seven to eight years before fully fault-tolerant quantum computers, with around half a million qubits, become standalone systems capable of handling full workloads in data centers.

How does the speaker view the potential philosophical implications of quantum computing?

The speaker briefly reflects on the philosophical aspects of quantum computing, particularly its similarities with the human brain and the potential overlap with simulation theory. However, they ultimately conclude that the focus should remain on practical advancements in the quantum computing field for the time being.
