# Quantum Computing Market Research, 2023

Popular accounts often imply that quantum computers, because superposition and entanglement allow them to carry out multiple computations at the same time, are simply faster versions of conventional computers. Compared to conventional computers, quantum computers are “unnatural” devices that might be best suited to a relatively narrow range of applications, notably simulating systems dominated by quantum effects. It’s no surprise that the top quantum computing graduate programs are hosted by some of the most prestigious schools. MIT is no exception, as its Lincoln Laboratory studies integrated nano-systems and quantum information. MIT’s masters in quantum computing focus on trapped-ion qubits as well as designing integrated quantum circuits.

This area of research is called computer architecture, and involves everything from how a quantum computer would interface with existing technologies to what types of software would be compatible with quantum systems. Creating well-functioning qubits is only one aspect of quantum computing. An equally important goal is the creation of a quantum information network — a quantum internet — that will be more secure than today’s internet. Nathalie de Leon, assistant professor of electrical engineering, is testing the viability of synthetic diamonds as devices that store and transmit information from one place to the next. Although a diamond may look clear and flawless, a close examination reveals something very different.

The potential misuse of quantum power is driving the search for new quantum cryptography methods. Over the last three decades, quantum researchers have come up with a handful of ways to make qubits. The heart of a qubit is typically a very small particle — such as an atom, ion or electron — that due to its tiny size exhibits quantum properties. The fundamental component of this new technology is the qubit, a quantum version of the classical bit that everyday computers use to represent information. A classical bit has a value of either 0 or 1, and joining these bits into strings enables computers to represent information such as letters and numbers.

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

Right now, we do not encounter the applications of quantum technology in our everyday lives. This means that when we talk about them, we have to talk about quantum phenomena. They challenge us, because we have no experience with, for example, superposition in our visible world, which is governed by conventional physics, where objects such as a chair can only be in one place in the room. I will answer this based on where the technology is today and what we think a quantum computer will be good at—and with this in mind—my guess would be that quantum computers will not be something we will have at home. It will not be a computer we can use to go on Facebook or watch YouTube videos.

available via IBM Cloud®. And despite all the hype, it’s a slow-moving one as well, Hensinger adds. “There’s not going to be this one point when suddenly we have a rainbow coming out of our lab and all problems can be solved,” he says.

IBM published research last year on a method that used quantum algorithms to outcompete conventional Monte Carlo simulations for assessing financial risk. In practice, the properties of entangled qubits are so delicate that it’s difficult to keep them around long enough to be put to much use. Quantum computer makers also contend with lots of engineering challenges — like correcting for high error rates and keeping computer systems incredibly cold — that can significantly cut into performance. Quantum computers conduct calculations by manipulating qubits in a way that plays around with these superimposed probabilities before making a measurement to gain a final answer.

The researchers can then use additional laser signals to set the trapped atom’s energy levels to represent quantum 0 or 1 states. In quantum computing, a qubit (/ˈkjuːbɪt/) or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two states can be taken to be the vertical polarization and the horizontal polarization.

## Quantum computing kit

Using today’s supercomputers to identify the best catalytic combinations to make ammonia would take centuries to solve. Ammonia is in high demand and is estimated to be a $77B global market by 2025, according to CB Insights’ Industry Analyst Consensus. Blockchain tech is being used more and more for applications within asset trading, supply chains, identity management, and much more. Though QKD currently faces practical challenges like the distance over which it is effective (most of today’s QKD networks are pretty small), many are expecting it to soon become a big industry. Toshiba, for instance, said in October that it expects to generate $3B in revenue from QKD applications by the end of the decade. If you’re a developer and would like actually to try using a quantum computer, it’s probably the easiest way to do so.

Since quantum systems are altered when measured, it’s possible to check if an eavesdropper has intercepted a QKD transmission. Done right, this means that even quantum computer-equipped hackers would have a hard time stealing information. By entangling qubits, researchers can build quantum circuits that can do complex calculations. Jason Petta, the Eugene Higgins Professor of Physics, is working on this challenge for silicon-based spin qubits.

The more

information you need to store, the more binary ones and zeros—and

transistors—you need to do it. Since most conventional computers can

only do one thing at a time, the more complex the problem you want

them to solve, the more steps they’ll need to take and the longer

they’ll need to do it. Some computing problems are so complex that

they need more computing power and time than any modern machine could

reasonably supply; computer scientists call those intractable

problems. The Pittsburgh Quantum Institute (PQI) at Carnegie Mellon University hosts over 100 members and workers to create a multidisciplinary quantum computing graduate program that involves engineering, business, philosophy of science, and other fields.

### Report on Military Applications for Quantum Computing

Rigetti, trading at about a 10th of its initial price, is losing its founding CEO on Thursday. “I don’t think there will be a quantum winter, but some people will get frostbite,” Global Quantum Intelligence analyst Doug Finke said at Q2B. The Institut Polytechnique de Paris is one of France’s most prestigious universities, as it hosts the Center for Theoretical Physics (CPHT). Their quantum physics degree programs offer students a wide range of physics topics, from condensed matter to particle physics. The coining of the term qubit is attributed to Benjamin Schumacher.[1] In the acknowledgments of his 1995 paper, Schumacher states that the term qubit was created in jest during a conversation with William Wootters. PhD student Sahra Kulmiya, who carried out the Sussex experiment, says that the team are ready for the challenge to take the technology to the next level.

## Q&A: Why is there so much hype about the quantum computer?

Quantum computing has the capability to sift through huge numbers of possibilities and extract potential solutions to complex problems and challenges. Where classical computers store information as bits with either 0s or 1s, quantum computers use qubits. Qubits carry information in a quantum state that engages 0 and 1 in a multidimensional way. Quantum computing employs the properties of quantum physics like superposition and entanglement to perform computation. Traditional transistors use binary encoding of data represented electrically as “on” or “off” states. Quantum bits or “qubits” can simultaneously operate in multiple states enabling unprecedented levels of parallelism and computing efficiency.

### Superconducting qubits have passed a key quantum test

That would conceivably happen either through better engineering, discovering optimal circuit layout, and finding the optimal combination of components. That is, rather than having to perform tasks sequentially, like a traditional computer, quantum computers can run vast numbers of parallel computations. Quantum computing solves mathematical problems and runs quantum models using the tenets of quantum theory. Some of the quantum systems it is used to model include photosynthesis, superconductivity and complex molecular formations.
