The Week in Quantum Computing - January 9th - 2023 Ahoy!

The Week in Quantum Computing. Brought to you by Sergio Gago (@piratecto).

Quick Recap

So, 2023 is here. Two weeks ago, before we went on holidays we published a collection of 2023 quantum predictions, now it is the time to make them happen. But in the meantime a big claim was made. A group of researchers from China claimed could break RSA-2048 with some 370 physical qubits. The community had a lot to say but you can review our official response from Moody’s here.
Israel makes a bigger push with an additional $32M to their funding. US National Quantum initiative presents the supplement to their strategy after Biden signature. A spotlight on the usages of annealers (whether they are Dwave, QCI, Fujitsu or others is at the readers discretion). Riken advances on the integration of Fugaku super computer with quantum capabilities. A new study by MIT research where they improve the single-photon emission with a high-fidelity, on-demand, directional, microwave. Which is incredibly relevant for quantum networks. IBM claims is well on track on their roadmap to achieve advantage by using error mitigation by 2026, and that pairs really well with their qubit scalability plans. That also clashes with the fact that they don’t lead anymore in the amount of papers / research published (even though they say they are not interested in that anymore). Lastly, Brian demonstrates that a Quantum Computer can give us the answer to the ultimate question of Life, the Universe and Everything with a exponential speed up (given that Deep Thought could only do it in 7,5M years…).
Before you jump into hype conclusions, read Brian’s article, or even better, read Douglas Adams. Actually, read both!

Joe Fitzsimons @jfitzsimons

I was asked recently to give predictions for QC in 2023. Here's what I said: 1. Death of NISQ 2. Further progress on fault-tolerance 3. Trouble for PQC 4. Clearer understanding of quantum advantage Four days into the year, and #4 seems to be coming true: arxiv.org/abs/2301.00995

How the quantum realm will go beyond computing

After all, we have computers already, which have been around since the 1940s. Is the interest because of the use cases? Better AI? Faster and more accurate pricing for financial services firms and hedge funds? Better medicines once quantum computers get a thousand times bigger?

Companies are relying on quantum annealers for useful computations

While many companies are now offering access to general-purpose quantum computers, they're not currently being used to solve any real-world problems, as they're held back by issues with qubit count and quality.

Beyond scheduling, quantum can deliver in other ways for airlines

The recent Southwest Airlines fiasco highlighted a potential opportunity to use quantum computing technology for airline scheduling optimization, but quantum computing also could have a positive impact in other ways as similar situations arise in the future.

New quantum computing architecture could be used to connect large-scale devices

MIT researchers have developed a quantum computing architecture that will enable extensible, high-fidelity communication between superconducting quantum processors. In work published today in Nature Physics, MIT researchers demonstrate step one, the deterministic emission of single photons — information carriers — in a user-specified direction. Their method ensures quantum information flows in the correct direction more than 96 percent of the time.

Paper (The controversial one) Factoring integers with sublinear resources on a superconducting quantum processor

Shor's algorithm has seriously challenged information security based on public key cryptosystems. However, to break the widely used RSA-2048 scheme, one needs millions of physical qubits, which is far beyond current technical capabilities. Here, we report a universal quantum algorithm for integer factorization by combining the classical lattice reduction with a quantum approximate optimization algorithm (QAOA). The number of qubits required is O(logN/loglog N), which is sublinear in the bit length of the integer N, making it the most qubit-saving factorization algorithm to date. We demonstrate the algorithm experimentally by factoring integers up to 48 bits with 10 superconducting qubits, the largest integer factored on a quantum device. We estimate that a quantum circuit with 372 physical qubits and a depth of thousands is necessary to challenge RSA-2048 using our algorithm. Our study shows great promise in expediting the application of current noisy quantum computers, and paves the way to factor large integers of realistic cryptographic significance.

IBM On Track To Achieve Quantum Advantage By 2026 Using Error Mitigation

Noise is currently quantum computing’s biggest challenge as well as its most significant limitation. IBM is working to reduce that noise in the next few years through various types of quantum error management until true quantum error correction (QEC) is attained.
