Quantum Computing: Harnessing the Puzzling Power of the Subatomic In the heart of computers lies the way they encode information – the familiar 'bits' which can be either 0 or 1. Quantum computing upends this notion, replacing bits with 'qubits,' which exploit the mind-bending behavior of the universe at tiny scales. The Weirdness of the Quantum World In quantum computing there's something called superposition. This is the ability of a quantum system to be in multiple states at the same time until it is measured. There's also something called entanglement, which is when Qubits can become mysteriously linked, or 'entangled.' Once entangled, measuring one instantly affects the other, even across vast distances. Why Does This Matter for Computing? Well, in quantum computing there's something called massive parallelism. That's a traditional 3-bit computer that can hold one of eight possible combinations (000, 001… 111). A 3-qubit quantum computer can hold all eight at the same time. This scales rapidly. For example, 50 qubits can store all 2^50 states, outstripping powerful supercomputers. Quantum computing lets us tackle some crucial problems that are practically impossible to solve with classical computers. We can discover new medicines, designing ultra-efficient materials, and break modern encryption codes. How Do We Build a Quantum Computer? Unlike transistors in laptops, qubits are incredibly fragile. Superconducting circuits will be needed to cool near absolute zero to display quantum behaviors. Companies like Google and IBM utilize this approach. Also, trapped Ions will need to be suspended by lasers and electric fields, acting as remarkably stable qubits. The Challenges Ahead Quantum states are easily upset by noise and heat, which makes for error-prone Qubits. Error correction mechanisms are complex and resource intensive. Today's machines have dozens, maybe hundreds of qubits. For meaningful problem-solving, thousands or even millions will be needed. So, there's a huge need to scale up quantum computing. Now, the algorithms designed for classical computers cannot simply run on quantum systems. Entirely new thinking is required to harness their power. The Potential Transformations Despite the hurdles, if quantum computing reaches its potential, expect revolutions in drug discovery, which will simulate complex molecules to accelerate pharmaceutical development. In materials science, we'll able to design novel materials for batteries and solar cells. In finance, we'll be able to create highly complex models for risk assessment and portfolio optimization. In cybersecurity, we'll be able to potentially break existing encryption while spurring new quantum-resistant methods. The Race is On Governments and multinational corporations are investing heavily. While quantum supremacy has been claimed, fully practical quantum computers remain distant. It's a marathon, not a sprint, with potentially world-changing implications at the finish line.

QuEra Computing Inc. announced their roadmap to a fault-tolerant quantum computer yesterday. While it's never easy to comment on another company's achievements, especially when they're using a technology you're not familiar with, this is an important step forward for everyone interested in fault-tolerant quantum computing. So, I'll try to share some of my personal thoughts on this announcement. Yes, personal thoughts, not an AI-generated summary of the video! How cool is that, in 2024? Of course, I might say something wrong or inaccurate, and I won't be able to blame it on the AI. Should this happen, I'm confident the comments section will be quick to point it out ;) 👉 It is very nice to see a presentation so focused on achieving logical qubits. Logical qubits are the only way we can reach error rates low enough to run algorithms with a proven speedup. 👉 100 logical qubits will be an impressive achievement, especially if it comes as early as 2026. It is far beyond what a classical computer can simulate, at least in the general case. 👉 Some progress has been made to extend the number of qubits that can be simulated in some specific cases, but this cannot always be done. It is likely that 100 logical qubits will indeed yield a practical advantage. 👉 The scaling capabilities of the neutral atom platform are very interesting. Not having to "wire every individual pixel", as they say, is a big advantage. 👉 Practical advantage will depend on the error rates the logical qubits can achieve. While the current physical two-qubit gate fidelity is 99.5%, meaning an error rate of almost 1e-3, the logical gates must be far better. Depending on who you ask, you'll hear the target should be 1e-6, or 1e-9, or even 1e-12, but no target error rates were given here anyway. 👉 Practical advantage will also depend on the device's logical clock speed. As I shared previously, individual operations are slower on quantum computers than on classical computers. Neutral atoms are already one of the slowest platforms, and error correction adds an overhead on top of that. 👉 Upcoming software developments may help us to learn more about that: the presentation mentions "resource estimation" and a "logical qubit simulator", which will both be very useful to assess what can or can't be done. Resource estimation, in particular, is about estimating how many qubits and how much time is needed to run a specific algorithm - it should answer my concerns above. 👉 Non-Clifford gates (planned for 2025) will be essential to make the roadmap work and the computer useful. Clifford gates can be emulated in polynomial time on a classical computer. Logical qubits that only support Clifford gates cannot provide the exponential speedup which, as far as we know, is required to reach a practical advantage soon. I'm looking forward to seeing how this roadmap will unfold and how others will react. The race for logical qubits is definitely on, and it will be an exciting one!
