Institute for Molecular Science (hereinafter "the IMS"), National Institutes of Natural Sciences, has established a "Commercialization Preparatory Platform (PF)" to accelerate the development of novel quantum computers, based on the achievement of a research group led by Prof. Kenji Ohmori. The launch of the PF was made possible by collaboration with 10 industry partners, including companies and financial institutions.

The 10 partners that joined the PF include (listed alphabetically): blueqat Inc., Development Bank of Japan Inc., Fujitsu Limited, Groovenauts, Inc., Hamamatsu Photonics K.K., Hitachi, Ltd., and NEC Corporation.

With the PF in place, the IMS will leverage the expertise of the participating companies and seek for advice and support on matters related to commercialization, such as the processes of establishing a start-up company, developing domestically produced quantum computers, and R&D efforts to enable practical application of quantum computers and their associated services. It plans to launch a start-up company by the end of its FY2024 and begin the development of "cold (neutral) atom" quantum computers.

Background Fierce competition is underway globally for the development of quantum computers by various modalities. However, there remain a number of issues that need to be addressed in order to ensure that these computers can be used practically; these issues include the need to expand the scale of these computers and the ability to take measures against errors that may occur during computation. In recent years, the "cold (neutral) atom" modality, which uses individual atoms as qubits, has been attracting attention from industry, academia, and governments around the world as a revolutionary new method to overcome these issues. Another feature of the cold (neutral) atom modality is that it operates at room temperature and does not require any refrigerators, which are necessary for the superconducting qubit and silicon qubit modalities.

The Ohmori group at the IMS is leading the world in developing the cold (neutral) atom quantum computers. The group has a number of technological advantages and core competencies (*1), including "optical tweezers" and microscope technologies to control a large number of high-quality qubits on a flat surface, and "ultrafast two-qubit gates" that use an ultrafast laser to create a quantum entanglement between two qubits in just 6.5 nanoseconds. In particular, the two-qubit gates represent an important core technology that enables the extraordinary computational speed of quantum computers. In 2022, the ultrafast two-qubit gates developed by the Ohmori group achieved a disruptive innovation that accelerates the two-qubit gates of the conventional cold (neutral) atom method by two orders of magnitude at once.

By taking advantage of these technical advances and core competencies of the Ohmori group, the IMS will accelerate the development and commercialization of quantum computers in collaboration with its industry partners.

World's first demonstration of quantum supremacy using superconducting quantum computers in 2019 (*2) Message from Professor John Martinis, University of California, Santa Barbara: "Professor Kenji Ohmori and his team have recently made a major breakthrough to overcome the weakness of the neutral atom method by using ultrafast lasers to drastically accelerate its two-qubit gate by two orders of magnitude. Their optical tweezers and microscope technology for manipulating individual atomic qubits is also outstanding. The team is therefore an extremely promising candidate for the realization of a practical quantum computer in the near future. I would like to actively participate in and contribute to the practical application and commercialization of their quantum computer by making use of my experience."

Message from Yuki Takemori, General Manager, Innovation Promotion Office, Business Planning & Coordination Department, Development Bank of Japan Inc. Project General Manager of PF: "After the bursting of the bubble economy, the Japanese economy spent the 'lost 30 years' without a clue to its further growth. I expect that quantum computing will be a technology that will bring revolutionary evolution to mankind, similar to the Internet and artificial intelligence (AI). It will grow into an extremely important industry for Japan, acting as a catalyst for its development and advancement. The technological capabilities of Professor Kenji Ohmori and his team are a global treasure and a trump card for the revival of the Japanese economy. I expect that this project will spread its wings far and wide."

Message from Professor Kenji Ohmori, Institute for Molecular Science: "I would like to express my sincere gratitude for the support of such distinguished companies for the development of our cold-atom (neutral-atom) quantum computer. Although we have absolute confidence in our basic technology, the development of practical quantum computers requires the integration of a variety of 'enabling technologies' including conventional electronics, software, system engineering, and architecture. With the launch of this commercialization platform, we will further strengthen our development efforts and work hard to create a quantum computer that can contribute to our society as soon as possible."

Notes: (*1) Core competency: a defining capability that distinguishes an enterprise from its competitors (*2) Quantum supremacy: a demonstration of a quantum computer's advantage over classical computers, including supercomputers, to process calculations that would conventionally take a long time to process at unmatched speeds

Ethereum gears up against quantum threats. How does the community react to Buterins new proposal, and how real is the danger?

The exponential advancement of quantum computing technology poses a daunting challenge to the blockchain platforms, potentially undermining the security protocols that form the bedrock of these networks, with Ethereum (ETH) being no exception.

In response to this pressing concern, Vitalik Buterin, co-founder of Ethereum, has spearheaded discussions on Ethereum Research, aiming to address and mitigate the vulnerabilities quantum computing introduces to Ethereum.

Buterin foresees a potential quantum emergency, where the advent of quantum computing capabilities could lead to large-scale theft of Ethereum assets.

To counter this impending threat, Buterin proposed a multifaceted approach, starting with the implementation of a hard fork of the Ethereum network.

This hard fork would effectively rewind the network to a state before any potential thefts occurred, requiring users to adopt new wallet software explicitly designed to thwart future attacks.

At the center of Buterins strategy lies the adoption of a new transaction type outlined in Ethereum Improvement Proposal (EIP) 7560. This transaction type leverages advanced cryptographic techniques, including Winternitz signatures and zero-knowledge proof technologies like STARKs, aiming to shield transactions from quantum attacks by safeguarding users private keys from exposure.

Furthermore, Buterin advocates for the integration of ERC-4337 account abstraction for smart contract wallets, increasing security by preventing the exposure of private keys during the signing process.

Account abstraction acts as a smart contracts wallet, enabling users to interact with the Ethereum network without possessing their private keys or needing to maintain Ether for transaction costs.

In the event of a quantum emergency, users who havent executed transactions from their Ethereum wallets would remain shielded, as only their wallet addresses are public.

Buterin also suggested that the infrastructure necessary to enact the proposed hard fork could theoretically commence development immediately.

The Ethereum community is actively discussing Buterins proposal for a hard fork strategy to protect Ethereum from possible quantum attacks. This topic has sparked both interest and concern among members.

While the importance of preparing for quantum threats is recognized, there is skepticism about how effective these measures will be against malicious users with access to quantum computing. DogeProtocol, a community member, has raised questions about identifying legitimate account holders versus attackers in scenarios where quantum computers can break into Ethereum wallets.

DogeProtocol suggested using NIST standardized algorithms combined with classical algorithms. However, this could lead to larger block sizes due to the bigger signature and public key sizes in many post-quantum methods.

Another community member, nvmmonkey, recommends a preemptive strategy. They suggest integrating a machine learning system in Ethereums node network to spot large, suspicious transactions that could indicate unsafe activities, triggering emergency protocols like the Stark emergence fork.

Blockchain technology, including cryptocurrencies like Bitcoin and Ethereum, relies on cryptographic algorithms such as the Elliptic Curve Digital Signature Algorithm (ECDSA) to secure transactions and maintain the integrity of the distributed ledger.

However, quantum algorithms, notably Shors algorithm developed by Peter Shor in 1994, pose a threat by potentially solving the discrete logarithm problem on elliptic curves, which is the basis for ECDSAs security.

This capability could allow a quantum computer to forge digital signatures and, thereby, control any funds associated with those signatures.

Quantum computers could also undermine other cryptographic practices within blockchain technology, including the process of hashing, which is central to mining and the creation of new blocks.

While hashing (e.g., SHA-256 in Bitcoin) is not directly broken by Shors algorithm, Grovers algorithm, another quantum algorithm, could theoretically speed up the process of finding a hashs preimage, though the speed-up is less dramatic than Shors for encryption.

Although current quantum computers are not yet capable of breaking ECDSA on a practical scale, the rapid pace of progress suggests that the threat could become real within the next few years. Google plans to construct a quantum computer capable of handling extensive business and scientific calculations error-free by 2029.

IBM recently presented IBM Quantum Heron, its most advanced quantum processor. This processor stands out for its high performance and low error rates. IBM also unveiled the IBM Quantum System Two, a new modular quantum computer. This system, already in operation in New York, is designed to tackle complex scientific and business calculations.

The quantum threat to current cryptography is a fact widely acknowledged by researchers. There is an increasing emphasis on developing and implementing quantum-resistant or post-quantum cryptographic algorithms.

For example, the National Institute of Standards and Technology (NIST) has initiated a process to evaluate and standardize quantum-resistant public-key cryptographic algorithms. These could be crucial steps towards maintaining the security and resilience of blockchain and other digital infrastructure in the face of quantum computing.

As quantum computers capabilities evolve, the collaborative engagement of researchers, developers, and policymakers will become essential.

By prioritizing the development and integration of quantum-resistant cryptographic solutions, the blockchain community can safeguard sensitive information, preserve digital trust, and ensure the continued viability of blockchain in the quantum era.

Quantum Tic-Tac-Toe: Quantum Tic-Tac-Toe is a fascinating adaptation of the traditional game, injecting quantum mechanics into the classic grid-based strategy. In this quantum variant, players are introduced to the concept of superposition, allowing a quantum piece to exist in multiple states simultaneously. Unlike classical Tic-Tac-Toe, where each cell can either be X or O or empty, quantum superposition introduces the possibility for a cell to contain both X and O states simultaneously until observed.

Quantum Chess: Quantum Chess fuses classic chess strategy with the principles of quantum mechanics. In this variant, developed by physicist Chris Cantwell, each piece on the board is assigned a quantum state, allowing it to exist in a superposition of multiple classical states simultaneously. This introduces an entirely new layer of complexity and strategy, as players can leverage the principles of superposition and entanglement to create intricate moves and surprise their opponents. The game introduces the concept of quantum moves, where a player can move a piece in a superposition of multiple ways until the move is observed. Additionally, entanglement enables the connection of pieces states across the board, causing the state of one piece to instantaneously affect another. Quantum Chess challenges players to think beyond the classical constraints of traditional chess, encouraging a deeper understanding of quantum concepts while delivering an intellectually stimulating and entertaining gameplay experience.

Quantum optimisation: Quantum optimisation represents a revolutionary paradigm in problem-solving, leveraging the computational capabilities of quantum computers to address complex optimisation challenges. Traditional optimisation problems, which arise in fields such as logistics, finance, and artificial intelligence, often become exponentially more challenging as the scale of the problem increases. Quantum optimisation algorithms, like the Quantum Approximate Optimisation Algorithm (QAOA), harness quantum parallelism and interference to explore vast solution spaces efficiently. Quantum optimisation algorithms excel at finding optimal solutions by leveraging the inherent properties of superposition and entanglement. These algorithms can potentially outperform classical optimisation approaches for certain problem instances, offering a promising avenue for industries seeking to enhance efficiency and streamline decision-making processes.

Quantum computing holds immense promise in transforming both cybersecurity and Artificial Intelligence (AI) landscapes. The advent of quantum computers poses a potential threat to classical cryptographic methods, particularly those relying on factorisation and discrete logarithm problems. Conversely, quantum-safe cryptographic algorithms, such as those based on lattice cryptography or hash-based techniques, are being developed to fortify digital security in anticipation of quantum threats. The race to quantum-proof encryption methods is crucial for ensuring the resilience of sensitive data against the exponentially enhanced computational power of quantum adversaries.

On the AI front, quantum computing offers exciting prospects for accelerating machine learning algorithms. Quantum Machine Learning (QML) algorithms leverage quantum principles to enhance the efficiency of tasks such as pattern recognition, optimisation, and data analysis. Quantum computers, with their ability to process vast data sets and explore complex solution spaces simultaneously, have the potential to outperform classical computers in certain machine learning applications. The synergy between quantum computing, cybersecurity, and AI opens new frontiers for technological advancement, calling for interdisciplinary research to harness quantum capabilities for both securing digital landscapes and enhancing the efficiency of intelligent systems.
