The Week in Quantum Computing - October 10th
Issue #108
The Week in Quantum Computing. Brought to you by Sergio Gago (@piratecto).
Quick Recap
And the Nobel goes to quantum. Aspect, Clauser and Zellinger have won the nobel prize of Physics for their breakthrough at succesfully demonstrating quantum entanglement following the steps of Bell. Just a couple of weeks after three other big ones won the breakthrough prize.
Airbus leads series A for Qunnect for $8M. A new report claims 23% of organizations either are working or plan to work with quantum computers. Meanwhile Intel makes strides to mass production of scalable qubits. Last week we knew how much does a quantum data center cost. Well, IBM is pouring $20B (towards many things, including quantum). His face says it all :)
Three papers published on quantum for finance that surely will ignite the problem of “advantage vs reality”

Paper: Portfolio Optimization via Quantum Zeno Dynamics on a Quantum Processor
Portfolio optimization is an important problem in mathematical finance, and a promising target for quantum optimization algorithms. The use cases solved daily in financial institutions are subject to many constraints that arise from business objectives and regulatory requirements, which make these problems challenging to solve on quantum computers. We introduce a technique that uses quantum Zeno dynamics to solve optimization problems with multiple arbitrary constraints, including inequalities. We show that the dynamics of the quantum optimization can be efficiently restricted to the in-constraint subspace via repeated projective measurements, requiring only a small number of auxiliary qubits and no post-selection. Our technique has broad applicability, which we demonstrate by incorporating it into the quantum approximate optimization algorithm (QAOA) and variational quantum circuits for optimization. We analytically show that achieving a constant minimum success probability in QAOA requires a number of measurements that is independent of the problem size for a specific choice of mixer operator. We evaluate our method numerically on the problem of portfolio optimization with multiple realistic constraints, and observe better solution quality and higher in-constraint probability than the state-of-the-art technique of enforcing constraints by introducing a penalty into the objective. We demonstrate the proposed method on a trapped-ion quantum processor, observing performance improvements from circuits with two-qubit gate depth of up to 148.

Cloudflare’s post-quantum cryptography protects almost a fifth of the internet
The countdown to Y2Q, the day when quantum computers can decrypt public key algorithms, is on. While researchers don’t know exactly when this will happen, the Cloud Security Alliance (CSA) estimates this could be as soon as April 14, 2030.
Although many organizations are waiting for post-quantum threats to become tangible before taking action against them, other providers like Content Delivery Network (CDN) giant Cloudflare are diving straight in and responding with quantum-safe solutions.

Thriving As A Woman In a Male-Dominated Industry: Denise Ruffner of Atom Computing On The Five Things You Need To Thrive and Succeed as a Woman In a Male Dominated Industry
In the United States in 2022, fields such as Aircraft piloting, Agriculture, Architecture, Construction, Finance, and Information technology, are still male-dominated industries. For a woman who is working in a male-dominated environment, what exactly does it take to thrive and succeed? In this interview series, we are talking to successful women who work in a Male-Dominated Industry who can share their stories and experiences about navigating work and life as strong women in a male-dominated industry. As a part of this series, we had the distinct pleasure of interviewing Denise Ruffner.

EU deploys first quantum technology in six sites across Europe
Today, the European High-Performance Computing Joint Undertaking (EuroHPC JU) has announced the selection of six sites that will host the first European quantum computers: in Czechia, Germany, Spain, France, Italy, and Poland. They will be integrated on site into existing supercomputers, and will form a wide network across Europe. The total planned investment is over €100 million, half of which comes from the EU and the other half from the 17 countries participating in the EuroHPC JU. Academic researchers and the industry, no matter where in Europe they are located, will be able to access these six quantum computers based on state-of-the-art European technology.

Paper: Portfolio optimization with discrete simulated annealing
Portfolio optimization is an important process in finance that consists in finding the optimal asset allocation that maximizes expected returns while minimizing risk. When assets are allocated in discrete units, this is a combinatorial optimization problem that can be addressed by quantum and quantum-inspired algorithms. In this work we present an integer simulated annealing method to find optimal portfolios in the presence of discretized convex and non-convex cost functions. Our algorithm can deal with large size portfolios with hundreds of assets. We introduce a performance metric, the time to target, based on a lower bound to the cost function obtained with the continuous relaxation of the combinatorial optimization problem. This metric allows us to quantify the time required to achieve a solution with a given quality. We carry out numerical experiments and we benchmark the algorithm in two situations: (i) Monte Carlo instances are started at random, and (ii) the algorithm is warm-started with an initial instance close to the continuous relaxation of the problem. We find that in the case of warm-starting with convex cost functions, the time to target does not grow with the size of the optimization problem, so discretized versions of convex portfolio optimization problems are not hard to solve using classical resources. We have applied our method to the problem of re-balancing in the presence of non-convex transaction costs, and we have found that our algorithm can efficiently minimize those terms.
