The Week in Quantum Computing - April 3rd
Issue #132
The Week in Quantum Computing. Brought to you by Sergio Gago (@piratecto).
Quick Recap
This week saw significant advancements in the field of quantum cryptography and communication. The European Commission granted €7M to the QUARTER consortium, led by LuxQuanta, for the development of quantum cryptography technologies. This funding aims to increase the maturity and readiness of quantum cryptography for deployment within the European Quantum Communication Infrastructure. Additionally, India's first quantum computing-based telecom network link is now operational, as announced by Telecom Minister Ashwini Vaishnaw. In a collaborative effort, QuSecure and Accenture successfully demonstrated the first multi-orbit data communications test secured with post-quantum cryptography, showcasing the reality and possibility of crypto-agility. And Quantropi partnered with Cyberbridge.
On the research front, Chinese scientists achieved a breakthrough in quantum error correction (QEC) based on superconducting QC. While a group at Oxford developed a robust quantum memory within a trapped-ion quantum network node, capable of storing information for extended periods. In a new approach to qubits, MIT researchers proposed using beams of light from two lasers of slightly different colors to measure and control the spins of atomic nuclei. We have seen a great paper by the JPMorgan group on hedgding with quantum (perhaps quantum stocks?) and on how to use tensor networks for image classification.
Horizon Quantum raised $18.1m in Series A investment. Do we still have growth in the industry? Yuval wrote a great piece arguing that some of the investments on the demand side are pivoting into AI, and I definetely see the same thing. Is this really a slowcession coming to Quantum? Well, stock prices seem to agree with that (with the exception of IonQ making good against their expected revenues!) What do you think?
The thread of the week goes again to Dulwich Quantum. The list of hype winners of 2022! Really worth reviewing the whole list :)

Paper: Increasing error tolerance in quantum computers with dynamic bias arrangement
Many quantum operations are expected to exhibit bias in the structure of their errors. Recent works have shown that a fixed bias can be exploited to improve error tolerance by statically arranging the errors in beneficial configurations. In some cases an error bias can be dynamically reconfigurable, an example being linear optical fusion where the basis of a fusion failure can be chosen before the measurement is made. Here we introduce methods for increasing error tolerance in this setting by using classical decision-making to adaptively choose the bias in measurements as a fault tolerance protocol proceeds. We study this technique in the setting of linear optical fusion based quantum computing (FBQC). We provide examples demonstrating that by dynamically arranging erasures, the loss tolerance can be tripled when compared to a static arrangement of biased errors while using the same quantum resources: we show that for the best FBQC architecture of Bartolucci et al. (2023) the threshold increases from 2.7% to 7.5% per photon with the same resource state by using dynamic biasing. Our method does not require any specific code structure beyond having a syndrome graph representation. We have chosen to illustrate these techniques using an architecture which is otherwise identical to that in Bartolucci et al. (2023), but deployed together with other techniques, such as different fusion networks, higher loss thresholds are possible.

Paper: Quantum Deep Hedging
Quantum machine learning has the potential for a transformative impact across industry sectors and in particular in finance. In our work we look at the problem of hedging where deep reinforcement learning offers a powerful framework for real markets. We develop quantum reinforcement learning methods based on policy-search and distributional actor-critic algorithms that use quantum neural network architectures with orthogonal and compound layers for the policy and value functions. We prove that the quantum neural networks we use are trainable, and we perform extensive simulations that show that quantum models can reduce the number of trainable parameters while achieving comparable performance and that the distributional approach obtains better performance than other standard approaches, both classical and quantum. We successfully implement the proposed models on a trapped-ion quantum processor, utilizing circuits with up to 16 qubits, and observe performance that agrees well with noiseless simulation. Our quantum techniques are general and can be applied to other reinforcement learning problems beyond hedging.

Practical overview of image classification with tensor-network quantum circuits
Circuit design for quantum machine learning remains a formidable challenge. Inspired by the applications of tensor networks across different fields and their novel presence in the classical machine learning context, one proposed method to design variational circuits is to base the circuit architecture on tensor networks. Here, we comprehensively describe tensor-network quantum circuits and how to implement them in simulations. This includes leveraging circuit cutting, a technique used to evaluate circuits with more qubits than those available on current quantum devices. We then illustrate the computational requirements and possible applications by simulating various tensor-network quantum circuits with PennyLane, an open-source python library for differential programming of quantum computers. Finally, we demonstrate how to apply these circuits to increasingly complex image processing tasks, completing this overview of a flexible method to design circuits that can be applied to industrially-relevant machine learning tasks.

MIT Engineers Discover a New Way To Control Atomic Nuclei As “Qubits”
Researchers at MIT have proposed a new approach to making qubits and controlling them to read and write data. The method, which is theoretical at this stage, is based on measuring and controlling the spins of atomic nuclei, using beams of light from two lasers of slightly different colors. The findings are described in a paper published in the journal Physical Review X, written by MIT doctoral student Haowei Xu, professors Ju Li and Paola Cappellaro, and four others.
