Error Corp: Shaping the Future of Error Control for Quantum Computers

Quantum computing promises to revolutionize numerous fields, from developing new materials and breaking encryption to solving complex optimization problems more efficiently than classical computers. 

However, a significant hurdle remains: error correction. With every step of a quantum computation, errors accumulate, ultimately leading to inaccurate results. This limits today’s quantum computers to performing only shallow calculations with a few qubits and steps, significantly constraining their potential.

Error Corp pioneers a new approach to detect and correct quantum errors more efficiently, promising to reduce the number of qubits required for quantum error correction drastically. Founded by Dennis Lucarelli, in early 2022, it has the potential to propel quantum computing beyond its current limitations and address some of the most challenging problems in science and technology.

Deep Dive: Smashing Google’s Quantum Supremacy Claims

In 2019, Google ran a particular calculation on its Sycamore quantum computer in 200 seconds that would have taken a classical supercomputer 10,000 years to complete. Thus, it claimed to have demonstrated quantum supremacy—a computation only a quantum computer could achieve in a reasonable timeframe. The results were published in Nature.

Now, a group of researchers from the Shanghai Artificial Intelligence Laboratory in China has shown that they can outperform Google’s sycamore processor for a similar computation in terms of speed and efficiency using a GPU cluster.

As detailed in their arXiv paper: “Notably, we have achieved a time-to-solution of 14.22 seconds with energy consumption of 2.39 kWh … outperforming Google's quantum processor Sycamore in both speed and energy efficiency, which recorded 600 seconds and 4.3 kWh, respectively.”

It shows how tricky it is to demonstrate quantum advantage, even when picking problems that quantum computers should be particularly good at solving. Computing is a moving frontier, as both classical algorithms and supercomputers keep improving. For more context, check out the articles by The Quantum Insider and NewScientist.

“Our spotlight is on a 20-qubit quantum computer, featuring the IQM Garnet QPU, which we will scale up to 150 qubits. Additionally, we share benchmarks for both the QPU and system levels, highlighting achievements such as a median 2-qubit gate fidelity of 99.5% and the genuine entanglement of all 20 qubits in a Greenberger-Horne-Zeilinger (GHZ) state.”

“In September 2023, I published AI’s $200B Question. The goal of the piece was to ask the question: “Where is all the revenue?” … If you run this analysis again today, here are the results you get: AI’s $200B question is now AI’s $600B question.”

“LLM routing offers a solution to this, where each query is first processed by a system that decides which LLM to route it to. Ideally, all queries that can be handled by weaker models should be routed to these models, with all other queries routed to stronger models, minimizing cost while maintaining response quality.”

“This paper presents APIGen, an automated data generation pipeline designed to synthesize verifiable high-quality datasets for function-calling applications. We leverage APIGen and collect 3,673 executable APIs across 21 different categories to generate diverse function-calling datasets in a scalable and structured manner.”
