# Report on Military Applications for Quantum Computing

The following is an incomplete list of physical implementations of qubits, and the choices of basis are by convention only. Different applications like Quantum sensing, Quantum computing and Quantum communication are using different implementations of qubits to suit their application. A quantum computer could in principle track the airflow with even greater accuracy, and do so really quickly, according to Prof Leigh Lapworth, who is leading the development of quantum computing for Rolls-Royce. So-called quantum particles can be in two places at the same time and also strangely connected even though they are millions of miles apart. Quantum machine learning is nowhere near being able to outperform classical algorithms, but there is room to explore, Kim says. A wide talent gap exists between the business need for quantum computing and the number of quantum professionals available to meet that need.

Our roadmap is a clear, detailed plan to scale quantum processors, overcome the scaling problem, and build the hardware necessary for quantum advantage. To speed computation, quantum computers tap directly into an unimaginably vast fabric of reality—the strange and counterintuitive world of quantum mechanics. While we are only at the beginning of this journey, quantum computing has the potential to lead to breakthroughs in science, business, and other domains. In the meantime, expect an increasing number of commercial applications to emerge that make use of near-term quantum computers or quantum simulators. It may not matter to businesses that these initial applications won’t represent quantum computing’s full potential — a commercial advantage doesn’t have to be revolutionary to still be lucrative.

The more qubits are quantum-mechanically linked, or entangled (see our explainer), within a quantum computer, the greater its computational power can grow, in an exponential fashion. It has already built numerous quantum computers, but it wants to develop a much more powerful 1,000-qubit machine by 2023. From a commercial side, the company runs a platform called the IBM Q Network that gives participants — including Samsung and JPMorgan Chase — access to quantum computers over the cloud and helps them experiment with potential applications for their businesses. The problem is compounded by the difficulty of building the hardware itself.

Brierley notes that drug discovery and materials-science applications might require quantum computers that can perform a trillion decoherence-free operations by current estimates — and that’s good news. Although 20 million qubits looks out of reach, it’s a lot less than the one billion qubits of previous estimates4. And researcher Michael Beverland at Microsoft Quantum, who was first author of the 2022 preprint2, thinks that some of the obstacles facing quantum chemistry calculations can be overcome through hardware breakthroughs. Although this was an important milestone in computing, it was more of a theoretical leap forward rather than a practical one, since the problem the quantum computer solved had no real-world use at all. But we’re rapidly approaching a time when quantum computers will have a real impact on our lives.

Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within our Office of Indigenous Relations. It explains and predicts the behaviour of atoms and molecules in a way that redefines our understanding of nature. It is the most precise description that we have of the world, and yet, it predicts surprising, often counter-intuitive behaviours. Quantum entanglement ensures that this new kind of internet is secure against hackers.

### Intel and QuTech Demonstrate Advances in Solving Quantum Interconnect Bottlenecks

Within the university are many research groups that study quantum devices and nano-systems. Because of its reputation, the University of Cambridge brings opportunities for network connections within the UK’s quantum hub. However, its main focuses are on quantum computing, quantum cryptography, and quantum information theory. To research these subjects in their master’s and Ph.D. programs, CQIST brings in experts from both the school of Arts and Sciences and Engineering, giving all students an interdisciplinary focus on quantum computing technology. In general, n qubits are represented by a superposition state vector in 2n dimensional Hilbert space. In the quantum realm, particles can be in two places at the same time and researchers want to harness this property to develop computers that can do multiple calculations all at the same time.

## Quantum Computing Achieving Quantum Practicality

PsiQuantum has partnered with the semiconductor manufacturer GlobalFoundries to achieve its goal. The machines will be room-sized, comparable to supercomputers or data centers. Qubits are made using physical systems, such as the spin of an electron or the orientation of a photon. These systems can be in many different arrangements all at once, a property known as quantum superposition.

Intel’s Horse Ridge II cryogenic control chip marks another milestone in the company’s progress towards overcoming scalability, one of quantum computing’s biggest hurdles. Intel Quantum SDK is a full quantum computing stack in simulation that offers a customizable development environment for a broad range of developers. Some think that quantum computing represents the next big paradigm shift for computing — akin to the emergence of the internet or the PC. Though it is uncertain when quantum computing may play an active role in national security, it is beyond doubt that no country will want to fall behind the capabilities of its rivals.

Researchers at Princeton are working to chart the future of quantum computing through foundational research in their labs and through collaborations with industry partners. We have decades of experience building ordinary, transistor-based computers with conventional architectures;

building quantum machines means reinventing the whole idea of a computer from the bottom up. First, there are the practical difficulties of making qubits, controlling them very precisely,

and having enough of them to do really useful things. Next, there’s a major difficulty with errors inherent in a quantum system—”noise” as this is technically

called—which seriously compromises any calculations a quantum computer might make. There are ways around this (“quantum error correction”), but they introduce a great deal more complexity.

### What is quantum computing?

Quantum computing’s threat to encryption extends to blockchain tech and cryptocurrencies — including Bitcoin and Ethereum — which rely upon quantum-susceptible encryption protocols to complete transactions. For example, D-Wave says that Volkswagen used its quantum annealer to make its paint shops more efficient by figuring out how to reduce color switching on its production line by more than a factor of 5. Meanwhile, Canadian grocer Save-On-Foods claims that D-Wave’s system helped it reduce the time taken to complete a recurring business analytics task from 25 hours per week to just 2 minutes. This quickening pace is being described by some as the start of a quantum version of Moore’s Law — one that may eventually reflect a double exponential increase in computing power. As I mentioned earlier, in practice, it’s probably best to run your quantum computer dozens of times or hundreds of times and pick the best result out of the many results you get. Now, in theory, a quantum computer is able to find one of the best solutions every time it runs.

### Electron-photon small-talk could have big impact on quantum computing

While today’s quantum processors are modest in size, their complexity grows

continuously. We believe this is the right time to build and engage a community

of new quantum learners, spark further interest in those who are curious,

and foster a quantum intuition in the greater community. By making quantum concepts more widely understood — even on a general

level — we can more deeply explore all the possibilities quantum

computing offers, and more rapidly bring its exciting power to a world

whose perspective is limited by classical physics. Financial applications, such as risk management, as well as materials science and logistics optimization also have a high chance of benefiting from quantum computation in the near term, says Biercuk. Still, no one is taking their eyes off the longer-term, more speculative applications — including quantum versions of machine learning.

## Quantum-centric supercomputing: The next wave of computing

However, it’s still much better than running the same problem on a regular computer and having to repeat the same type of computation one million million million million million times. When there are 3 people we need to divide into two cars, the number of operations we need to perform on a quantum computer is 1. This is because a quantum computer computes the score of all configurations at the same time. This article will not require you to have prior knowledge of either quantum physics or computer science to be able to understand it. Researchers are uncovering ways to harness and control these behaviours, advancing the quantum research field and finding new quantum applications.

Since 2016, IBM has worked with standards bodies to define new quantum-safe cryptography standards to prepare for this new era. And now, we’re bringing this expertise to the industry, with the IBM Quantum Safe offering to prepare our clients for the transition to post-quantum cryptography. IBM and Vodafone are partnering to prepare Vodafone and the telecommunications industry in their transition to quantum-safe cryptography. In today’s computers, software plays the role of coordinating and translating bits into calculations and results. Martonosi and her team are developing programs called compilers that read and translate high-level programming languages down to the level of the computer’s qubits. Quantum computing relies on the weird rules of atomic-scale physics to perform calculations out of reach of conventional computers like those that power today’s phones, laptops and supercomputers.
