Bluntly, if they don’t explain the actual underlying mathematical model, then you could spend years watching and rewatching such videos, and you’d never really get it. It’s like hanging out with a group of basketball players and listening to them talk about basketball. But unless you actually spend a lot of time playing, you’re never going to learn to play basketball. To understand quantum computing, you absolutely must become fluent in the mathematical model.

“The blurred line between industry and national security in China gives them an advantage,” says David Spirk, former chief data officer at the Department of Defense. Molecules—the building blocks of the universe—are multiple atoms bound together by electrons that exist as part of each. The way these electrons essentially occupy two states at once is what quantum particles replicate, presenting applications for natural and material sciences by predicting how drugs interact with the human body, or substances perform under corrosion. Traditional manufacturing takes calculated guesses to make breakthroughs through trial and error; by mirroring the natural world, quantum should allow advances to be purposefully designed. If anything, it’s surprising that traditional computing has taken us so far. From the trail-blazing Apple II of the late 1970s to today’s smartphones and supercomputers, all processors break down tasks into binary.

In 2007, the Polish city of Poznań erected a monument to three Polish mathematicians—Jerzy Rózycki, Henryk Zygalski, and Marian Rejewski—who in the 1930s began decrypting German Enigma cypher machines. Enigma-type encryption is similar to modern message encoding in that it relies on a vast number of potential codes to make it effectively unbreakable. In 1939 the Polish mathematicians shared their codebreaking with the British and the French, but the contribution of the Polish mathematicians was not widely known until decades later.

In an experiment by Rainer Blatt’s group at the University of Innsbruck, Austria, this has been successfully performed for up to fourteen ions. The next step is to scale the technology up to a bigger number of trapped ions. An ion trap is a system consisting of electric and magnetic fields, which can capture ions and keep them at locations.

## The future is happening now

First of all, if we have a quantum computer, it will be useful for scientists for conducting virtual experiments. Quantum computing started with Feynman’s observation that quantum systems are hard to model on a conventional computer. (This is known as “quantum simulation.”) For example, we could model the behavior of atoms and particles at unusual conditions (for example, very high energies that can be only created in the Large Hadron Collider) without actually creating those unusual conditions. Or we could model chemical reactions—because interactions among atoms in a chemical reaction is a quantum process. However, only if the older systems remain old and are not replaced by new encryption methods.

Historically, it has taken almost two decades to deploy our modern public key cryptography infrastructure. Therefore, regardless of whether we can estimate the exact time of the arrival of the quantum computing era, we must begin now to prepare our information security systems to be able to resist quantum computing. Quantum computers have the potential to revolutionize the field of computing, but they also come with a number of disadvantages. Some of the main challenges and limitations include noise and decoherence, scalability, error correction, lack of robust quantum algorithms, high cost, and power consumption.

### AI-Accelerated Technology Investment Guidelines for HPC

The course begins with an exploration of classes of computational problems that classical computers are not well-suited to solve. We then progress to an intuitive introduction to key QIS concepts that underlie quantum computing. Next, we introduce individual quantum operations, but with a symbolic representation and mathematical representation. A limited set of linear algebra operations will be taught so that students can calculate operation results. Finally, we string these individual operations together to create the first algorithm that illustrates the performance advantage resulting from these unique operations. An important criticism of these active error correction schemes,

however, is that they are devised for a very unrealistic noise model

which treats the computer as quantum and the environment as classical

(Alicki, Lidar, and Zinardi 2006).

Google is spending billions of dollars to build its quantum computer by 2029. The company opened a campus in California called Google AI to help it meet this goal. Once developed, Google could launch a Quantum computing service via the cloud. Quantum computers could be used to improve the secure sharing of information. Another area where quantum computing is expected to help is the environment and keeping water clean with chemical sensors. Theoretically, linked qubits can “exploit the interference between their wave-like quantum states to perform calculations that might otherwise take millions of years.”

The company wants to make large-scale quantum computers a reality within just 10 years. The efficacy of quantum computers in predicting the behavior, properties, evolution, and configuration of chemical and biological elements such as molecules and proteins, has been established. The immense power of QC emerges from three fundamental properties of qubits, viz. If or when powerful quantum computing arrives, it poses a large security threat.

### Learn quantum computing

In a third paper, Nichol, Kandel, and Qiao demonstrated another technique of transferring information between qubits, using an exotic state of matter called time crystals. A time crystal is a strange state of matter in which interactions between the particles that make up the crystal can stabilize oscillations of the system in time indefinitely. Imagine a clock that keeps ticking forever; the pendulum of the clock oscillates in time, much like the oscillating time crystal. The researchers were able to measure the power spectrum of noise of the silicon-based, electron spin-qubit device across an unprecedented 12 frequency bands. Noise has never before been measured over these types of frequencies in spin-qubit systems. “This research and our ongoing work to better understand the impact of quantum computing on the securities industry will help FINRA to continue to carry out its mission of investor protection and market integrity as the technology evolves,” he added.

## Argonne to receive new funding to develop quantum networks

The researchers believe that, with the new approach, close to 98 percent of all errors should be detectable with optimized protocols. This could reduce the computational costs of implementing error correction by an order of magnitude or more. Photons are another approach to building quantum computers, i.e., particles of light, which are rather isolated from the environment and therefore less prone to decoherence. This property allows the realization of long quantum states over long distances. Moreover, photons have multiple degrees of freedom, such that the highly scalable encoding of quantum information is feasible (Flamini et al. 2018). Due to their robustness and mobility, photons are best suited for transmitting quantum information in a very fast way.

### The Promised Bits

The idea is that the 100,000 qubits will work alongside the best “classical” supercomputers to achieve new breakthroughs in drug discovery, fertilizer production, battery performance, and a host of other applications. “I call this quantum-centric supercomputing,” IBM’s VP of quantum, Jay Gambetta, told MIT Technology Review in an in-person interview in London last week. In 2021, researchers at the University of Innsbruck in Austria and a spin-off company called Alpine Quantum Technologies unveiled a 29-qubit trapped-ion computer that could fit into a pair of server cabinets. Thomas Monz, CEO of AQT and a researcher at the university, says that there’s not enough detail on the new computers to meaningfully comment on them. The Forte Enterprise will be available from next year and feature 35 “algorithmic qubits” (AQ)—a metric invented by the company to denote the number of qubits in a processor that can be put to useful work, rather than the sheer number of physical qubits.
